In this article, youll learn what is Rolling mill and how it works and 6 types of rolling mills with explained with images and also you can download the PDF file of this post.Rolling Mills and TypesContents show1. Rolling Mills and Types2. Types of Rolling Mills2.1. 1. Two High Rolling Mills2.2. 2. Three High Rolling Mills2.3. 3. Four High Rolling Mills2.4. 4. Cluster Rolling Mill2.5. 5. Planetary Rolling Mill2.6. 6. Tandem or Continuous Mill3. ConclusionRolling mill is the extensively used process and the most expensive one in terms of equipment costs. It accounts for almost 90% of the metal produced by forming.Image credit: IndiamartIn the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the following steps, that is a number of passes through the rolls may be required to get the required configuration.During rolling initial passes results in a reduction of cross-sectional area, while intermediate passes try to bring the shape closer to the final shape and the final or finishing passes bring the material to the required shape and size. Plates, bars, rounds, structural shapes, sheets and strips can be obtained by rolling.Here are the some of similar article you can checkout:Heat treatment: Types, Working and Process of Heat TreatmentMetal Casting Process: Types of Moulding, Sands and Its classification.Types of Rolling MillsFollowing are the 6 different types of rolling mills used in many industries:Two high rolling millsThree high rolling millsFour high rolling millsCluster rolling millsPlanetary rolling millsTendem or Continuous mills1. Two High Rolling MillsIt contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable. The rolls rotate in opposite directions and are driven by electrical motors.The direction of rotation of rolls cannot be changed, therefore the work has to be fed into rolls from one direction only. If rolling requires more than one pass in the same set of rolls, the material will have to be brought back to the same side after the first pass.2. Three High Rolling MillsIt consists of three rolls positioned directly over one another as shown in the figure below. The direction of rotation of the first and second rolls are opposite as in the case of two high mills. The direction of rotation (path) of second and third rolls is always opposite to each other.Always all three rolls rotate in their bearings in the same direction. The advantages of this will mill is that work material can be fed in one direction between the first and second roll and the return pass can be provided in between the second and third rolls. This results in the transport of material from one side of rolls to the other.Read also: List of Mechanical Properties That Every Mechanical Engineer Should Know3. Four High Rolling MillsThe mill has four horizontal rolls, two smaller diameters and two much larger. The larger rolls are called backup rolls. The smaller rolls are the working rolls, but if they would be thicker in the centre and thinner at either end.Backup rolls hold the working rolls and restrict deflection when the material is being rolled. The usual products of these mills are hot and cold plates and sheets.4. Cluster Rolling MillIt consists of two small diameter working rolls and four or more backing rolls. The larger number of backup rolls provided becomes necessary as the backup rolls cannot exceed the diameter of working rolls by more than 2-3 times.5. Planetary Rolling MillIn the planetary mill type of rolling machine, a large backup roller is surrounded by a number of planetary working rollers as shown in the figure.Each planetary roll gives a continuous reduction. It is employed to reduce large thicknesses in a single pass of a steel strip. Its rolling capacity is higher than cluster machine but less than a tandem rolling machine.6. Tandem or Continuous MillIn this tandem mill types of rolling mill, It includes of a number of non-reversing two-high rolling mills provide one after other. So that the material can be passed through them all in order.This is only suitable for mass production work, as lower volumes require a quicker change of set up and they will consume a lot of labour and work.ConclusionSo now, we hope that we have clear all your doubts about Types of Rolling Mill.

The direction of rotation (path) of second and third rolls is always opposite to each other.Always all three rolls rotate in their bearings in the same direction. The advantages of this will mill is that work material can be fed in one direction between the first and second roll and the return pass can be provided in between the second and third rolls. This results in the transport of material from one side of rolls to the other.Read also: List of Mechanical Properties That Every Mechanical Engineer Should Know3. Four High Rolling MillsThe mill has four horizontal rolls, two smaller diameters and two much larger. The larger rolls are called backup rolls. The smaller rolls are the working rolls, but if they would be thicker in the centre and thinner at either end.Backup rolls hold the working rolls and restrict deflection when the material is being rolled. The usual products of these mills are hot and cold plates and sheets.4. Cluster Rolling MillIt consists of two small diameter working rolls and four or more backing rolls. The larger number of backup rolls provided becomes necessary as the backup rolls cannot exceed the diameter of working rolls by more than 2-3 times.5. Planetary Rolling MillIn the planetary mill type of rolling machine, a large backup roller is surrounded by a number of planetary working rollers as shown in the figure.Each planetary roll gives a continuous reduction. It is employed to reduce large thicknesses in a single pass of a steel strip. Its rolling capacity is higher than cluster machine but less than a tandem rolling machine.6. Tandem or Continuous MillIn this tandem mill types of rolling mill, It includes of a number of non-reversing two-high rolling mills provide one after other. So that the material can be passed through them all in order.This is only suitable for mass production work, as lower volumes require a quicker change of set up and they will consume a lot of labour and work.ConclusionSo now, we hope that we have clear all your doubts about Types of Rolling Mill.

the working principle of pharmaceutical roller compactor

the working principle of pharmaceutical roller compactor

SaintyCo Roll Compactors are cGMP and CE compliant machines that guarantee uniform particle distribution and increased bulk density. With our best market prices, SaintyCo Roll Compactors are available for both R&D and large scale dry granulation.

Clearly, you can see that a thorough understanding of this equipment is vital in ensuring quality material processing process. It is only through this that you can achieve a mixture that looks like this:

Basically, the idea behind dry granulation is that a fine powder that is subjected to a predetermined amount of force that transforms it into a compact sheet or solid. The key factors that determine the efficiency of the compaction process include:

Our machines come with a suitable feed system that allows the powder to flow seamlessly into the compaction chamber. Quite a number of rollercompactor manufacturers use horizontal screw within the feeding section.

At every stage, we strive to ensure efficiency and consistency of the pharmaceutical rollercompactor. For instance, the modern rollercompactors come with fully automated systems, with advanced safety measures.

Generally, the working principle of pharmaceutical rollercompactor is straightforward. But, understanding this process alone is not enough; you need to know the various components and the specific objectives of material processing.

the flaking roller mill for grains | | miller magazine

the flaking roller mill for grains | | miller magazine

Bhler has developed a new flaking roller mill especially for the flaking of various grains such as wheat, rye, spelt, barley and above all oats. As an integrated component of the entire grain processing process, the MDFA flaking roller mill sets new standards with regard to sanitation, food safety, product quality and convenience of use.

The worldwide consumption of grain flakes is rising. More and more consumers are realizing the healthy effect of flakes produced from different kinds of grain. The new MDFA flaking roller mill has been specially developed by Bhler for the careful and high-quality manufacturing of flakes made from oats, rye, wheat, spelt and barley. The new flaking roller mill delivers one to four tons of grain flakes per hour, which are of consistently high quality. Of special importance when designing the new machine was the highest possible level of sanitation, low maintenance, low operating costs and a simplified operation

HIGHER PERFORMANCE AND EFFICIENCY With the development of the new flaking roller mill, particular attention was paid to a robust design. This ensures safe continuous operation even under demanding production conditions. The automatic control of the roll temperature and the peripheral drilled rolls ensure an even roll temperature, and the high-quality rolls with a diameter of 600 mm guarantee optimum surface pressure. Both make a significant contribution to consistent and high product quality. The centrally positioned lubricating spot and the option of changing the rolls from front to rear shorten maintenance times.

THE HIGHEST LEVEL OF SANITATION The new MDFA flaking roller mill from Bhler has a direct drive without belts. The speed ratio of the flaking rolls can be set precisely via the EasyFlake control system. This drive principle as well as the automatic roll adjustment with spindle, instead of hydraulics, improves food safety. The risk of contamination from oil is largely prevented.

The design of the flaking roller mill is extremely maintenance-friendly. It guarantees optimal accessibility, which simplifies and speeds up cleaning. The roller wedge is easy to disassemble for cleaning. Finally, the integrated aspiration air feed ensures improved sanitation, as it effectively prevents the build-up of condensation.

THE HIGHEST LEVEL OF OPERATING CONVENIENCE The new Bhler flaking roller mill is fitted with the user-friendly EasyFlake machine control with touchscreen panel and 3D visualization. A variety of control functions enable the precise setting of production parameters. The adjustment of the speed of the feeding rolls therefore enables the throughput to be determined. It is also easy to control the roll gap, the roll temperature and the speed ratio of the flake rolls.

Besides the setting of parameters, the EasyFlake interface allows the operation of the flaking roller mill to be monitored at all times. The course of the motor current, the roll gap adjustment, the product temperature and the roll temperature are visible at a glance. The machine controls can be learnt in a very short time. This reduces the time spent on training and increases operating safety at the same time.

IN USE AT SWISSMILL The new MDFA flaking roller mill MDFA has been in operation since the end of 2015 at Swissmill, the largest Swiss manufacturer of oat flakes. They are very satisfied with the new member of staff at Swissmill. We have counted on the expertise and reliability of Bhler equipment for decades, explains head miller Erwin Waldvogel. The new flaking roller mill has convinced us thanks to its reliability and performance. The user-friendliness and time saved on cleaning and maintenance are also remarkable.

OAT FLAKES HEALTHY AND FILLING There is currently a trend towards the consumption of ready-made products made from oat flakes. It is of growing importance that they are not just quick to consume but should also be healthy and easy to digest. These requirements do great justice to oat flakes. It is therefore not surprising that the consumption of ready-made products with oat flakes has increased by 40% in the last ten years. Oat flakes have a high proportion of carbohydrates (70 %) and protein (15 %) as well as unsaturated fats and the soluble fiber beta-glucan. Beta-glucan can lower the cholesterol level and has positive effects on the blood sugar level, which reduces the feeling of hunger. Oat flakes are also free of gluten and contain avenanthramides, which have anti-inflammatory and cancer-inhibiting effects.

crushing, grinding and reduction in flour milling | | miller magazine

crushing, grinding and reduction in flour milling | | miller magazine

It is necessary to create a good control system at the factory to ensure the stability at the product quality. It must be studied meticulously in all stages of production so that the quality of product is good.

More functional and useful features have been added compared to the former ones with the development of electronics and automation in roller mills. Torque motors are used which we have made the R&D work for the years especially in the area of product supply. The product level is determined via sensor or loadcell integrated into the roller mill bottle and the feeding speed can be set according to the incidence rate. This provides a continuous product flow. Also the possible damage to the machine is minimized if there is any impaction through the sensors which can be put in different places, and the failure can be identified and rectified before the growth of failure. Lubrication systems are not on bearings one by one in the new generation of CERES II roller mills, they have been taken at a central point with easy access. Thus the lubrication is provided easily and in a short time. We can provide to lubricate in a stable form by controlling the centralized lubrication systems with the PLC system.

The front of the roller mills is made openable to make the roll changing operation more quickly and easily in roller mills and two rolls can be easily taken out along with the bearings. Thus, the changing of rolls can be made in a short time and production will have to stop for long periods.

THE EFFECT OF ROLLER MILL ROLLS TO GRINDING There are two types of roller mill rolls as Crushing roller mill rolls and reduction roller mill rolls; 1. Crushing roller mill rolls make an angle on rollers in order to fulfill the wheat cutting-opening, excavating- eroding and crushing and spliting missions, to do so, it has extending threads. Their numbers, angles, and heights in centimeters vary depending on how these threads will destroy and cut the product. Unless appropriate selection of roller threads, there will be problem related to efficiency and quality.

2. Reduction roller mill rolls are straight roller mill rolls. The task of reduction roller is gradually to convert semolina obtained in the crushing system into the flour and to make flake by crushing bran and germ particles. They make the compress, crushing and shredding tasks. Expansion occurs at the edges because of heat released due to compression and crushing in these rolls; A little camber is given to the middle part in order to ensure crushing in parallel and equally while running the rolls. This camber varies depending on the density and structure of the product to passage. If appropriate camber is not selected, a complete crushing can not be provided and thus quality defects with yield losses are seen.

ENERGY CONSUMPTION IN ROLLER MILLS Thanks to the advancement and the good use of technology today, the effort to make optimum production has increased with the minimum energy in the mill. Because the competition is increasing day by day. Therefore, machine manufacturers put in effort to make machines that can operate at maximum capacity by spending less energy. Also the selection of machine and the preparation of diagram according to the feature, capacity of raw materials to be processed and of product to be produced in making the factory projects directly affects the energy consumption. As a result of the development of machines, energy consumption has reduced rather than the former.

GRINDING GAP AND PARTICLE SIZE Grinding gap and particle size are reduced towards the end from roller mills which the grinding begins. The reason for this is that each process has disintegration and contraction while making gradually cutting, sorting and scraping actions during the separation of endosperm and bran. Therefore the grinding gap will be less in the next crushing process. This range varies depending on the chracteristics of the desired product, the performed diagram, tonnage and the humidity of the milled product.

TEMPERATURE CONTROL IN ROLLER MILL AND ROLL BEARINGS Temperature control is very important in especially reduction (liso) in other words straight roller mills. While making crushing and blasting operation in these roller mills, it may occur more heat. The crushing and blasting operation performed here should be applied so as not to impair the gluten and strach features of the flour. The roller mill rolls temperature should not be more than 40 to 45 degrees. If this remperature is more, there would be deterioration in the bread value of flour, also it begins to appear the deformations on the roller mill rolls and this temperature spreads to the bearings. The oil used in the bearings become thinner and exudes outward, in this case the life of the bearings is reduced.

STABILITY OF PRODUCT QUALITY It is necessary to create a good control system at the factory for ensuring the stability in the product quality. It must be studied carefully in all phases of production so that product quality is good. Things to pay attention are as follows: The supply of the right raw materials according to the product to be produced, the classification and storage of these raw materials, The making of the right wheat blending according to the product to be produced, Routine checks on time cleaning machines for cleaning of wheat in a good way, The wheat humidity is important for a standard milling. To be done right the quenching operation required to the wheat, After quenching according to the physical properties of wheat, the rest time is very important for coming to ideal humidity of the wheat. To rest at the right time. To maintain the tonnage constantly at the grinding part, Routin controls are made so that roller mill settings are stable.

FEEDING IN ROLLER MILLS The roller mill supply settings must be done in good way to obtain the maximum efficiency in the roller mills. Because if the product to rolls comes in the form of curtain and continuously among the roller mill rolls, grinding and milling process will be stabil; thereby the product coming to the sieves will be continuous and homogeneous. The feeding process is very important for the stability of product quality. Sensor and load cell system faciliates fairly in adjusting the product coming to the roller mills and the product given to the roller mill rolls. If the product to roller mill is thicker, the closeness of the roller mill rolls to each other is not importance, a shortage is seen in performing the crushing. So grain curtain setting and speed setting should be adjusted very well.

GRINDING CAPACITY Grinding capacity is calculated according to the factorys capacity. Crushing roller mill rolls should be up to approximately 40 percent of the total roller mill length, Reduction (liso) roller mill rolls are up to 60 percent of the total roller mill lenght. The average lenght of the roller mill is based on the account of12mm / 100kg /24 hours. This account is valid for standard flour mills. It varies according to the ratio of the products in the passages.

ROLLER MILL SETTINGS Roller mill settings can be adjusted according to three basic principles. The first is a setting done by hand. When the product is squeezed equally by keeping from both ends of the roller mill rolls, the decision is taken by touching The second is a setting done by eyes. Flaking and fragmentation of the milled product at both ends are looked with eye. The third is based on heat; the temperature in the roller mill rolls is synchronized with the heat meters from the both ends of the roller mill rolls and manually if there is no heat meter. It is effective to find the healthy setting to use these three method together while the roller mills are set. Also the product received from two sides of the roller mill rolls in the crushing roller mills can be adjusted, and can be adjusted according to the rate of product under the sieve by passing through laboratory sieve. For example about 30-35 percent of the particles must pass below 1000 microns sieve in B1 roller mills.

ROLLER MILL CARE AND MAINTENANCE PERIOD Maintenance and repair is a system that we still are forced to fix nowadays. As Aybakar, we committed to provide the necessary training on maintenance and repair to our customers. Our customers technical teams are trained at our factory and in customers factories prior to delivery of the machine.

The necessary maintenance intervals to be performed are as follows: Weekly maintenance Control of air supplies Control of roller mill rolls belt Control of the belt roller mills Cleaning of the roller engines Combining and opening the roller mill rolls

LUBRICATION Lubrication process may vary depending on operating speed and ambient temperature. Aybakars proposal is that lubrication is made from the central system per 1000 hours. By a single point lubrication with 8 bearing of 4 roller in our single storey CERES II roller mills, central system has been designed and approximately 640-800 grams of oil should be pressed. Double storey CERES II roller mills has been designed by lubricating of 8 roller from 16 single point and approximately 2560-3200 grams of oil should be pressed.

I have used every processor on the market and the Fibertech processor is at the top. Thank you for a quality product.

We really like the way the new Horning heads perform in all crop conditions. Wear points are easily serviced, and breakdowns have been few. Service is minimal and all bearings are greaseable. We are very pleased with the head so far.

rolling mill production line: what is the principle of the electric induction furnace?

rolling mill production line: what is the principle of the electric induction furnace?

Electricinduction furnace is an induction heating equipment for bar, round steel, square steel, billet, steel pipe, steel plate, and other metals. The heating temperature is generally no more than 1250 degrees, which is suitable for pre forging heating in the forging industry and metal quenching and tempering heating in the heat treatment industry.

The relationship between the heating coil and the heated material (metal) of theelectricinduction furnace is the same as that of the coil on the primary and secondary sides of the transformer. The magnetic force line generated by the heating coil through the intermediate frequency current is concentrated on the heated object and induced by the electromagnetic, which generates vortex current, and the heated object will be heated.

According to the type and shape of metal, the proper frequency, power, heating time, holding time, coil shape of AC current can be selected to make the metal heating meet the heating process requirements.

The uniformity of radial temperature of non-ferrous metals such as steel bar, aluminum bar, and copper bar in electricinduction furnace depends on the correct selection of power frequency and heating time matching the diameter of the workpiece; The axial temperature is uniform and gradient temperature difference depends on the structure and heating mode of the sensor. The inductor structure of theelectric induction furnace adopts a spiral heating coil, each group of multi-layer coils can control power independentlyto realizegradient heating. Generally speaking, an induction furnace is used to make induction penetration of metal materials for extrusion or forging.

The intermediate frequency induction heating furnace consists of a feeding mechanism, mobile trolley, feeding mechanism, induction heating furnace, furnace cover mechanism, discharging roller and ingot carriage, operation control system, main circuit control system, and furnace transformer.

The heating speed of theelectricinduction furnace is fast with littleoxide scale. The medium frequency heating furnace uses the principle of electromagnetic induction, and the heat is generated by eddy current in the workpiece itself. It is especially suitable for precision forging.

The inductors oftheelectricinduction furnaces are interchangeable. There are many kinds of heating equipment in the production process, so it is necessary to set up a variety of induction heaters with a common frame. At this time, the sensor exchange can be completed in a very short time through the unique total up and down water quick-change connector of the electric furnace and the new channel exchange mechanism developed by the electricinductionfurnace.

There are many kinds of feeding and discharging structures in the medium frequency induction furnaces. According to customers' different process requirements, the electricinductionfurnace is equipped with different feeding and discharging machines to form the optimized combination of equipment. The specific forms include continuous type, intermittent type, etc. The discharging forms include tilting type, direct tilting type, etc.

The whole medium frequency induction heating furnace system of theelectricinductionfurnace can be equipped with an automatic feeding machine, discharging machine, discharging separator, and closed water circulation system according to the user's requirements.

The whole medium frequency induction heating furnace system of theelectricinductionfurnace has multiple protections, including water temperature and water pressure alarm of cooling water circuit, and upper and lower limit alarm of temperature.

Stability of the whole medium frequency induction heating furnace system of the electric induction furnace. The continuous feeding of large bars can reduce the impact on the medium-frequency power supply. The closed-loop control of temperature is composed of the power supply to ensure that the head and tail of the return heating temperature are consistent, and the temperature difference between the core and the meter is small.

First of all, many manufacturers sell steel bar medium frequency induction heating furnace equipment on the market. If there are different manufacturers, the price may be different. Sometimes the price of an induction heating furnace is very different, and the price is different.

If the model of the induction furnace is different, the price is different. There are many models and styles of steel barelectricinduction furnaces. Different models of steel bar heating furnaces have different prices.

Different brands of steel bar medium frequency induction heating furnaces have different prices. Not only in the electric induction furnace industry, but the product brand is also different, the price is different. In any industry, such as cosmetics, mobile phones, computers, and so on, the price of the brand directly affects the price of the product. The same is true for steel bar induction furnaces. The price difference between a big brand and a small brand is very big. However, it is still recommended to buy equipment of powerful brandswitha guarantee in terms of quality and after-sales.

If theelectric induction furnace manufacturing process is different, the price is different. At present, there are many manufacturers of steel bar induction heating furnaces in the market. Different induction heating furnace equipment manufacturers have different technical strengths, different production processes, different production costs, and different steel bar heating furnaces. Welding, machining, assembling, and painting of steel bar electric induction furnace are needed. The price of each process is different due to different technology and method.

The material and configuration of medium frequency induction furnaces are different, and the price is different. The cost of material is an important reason that affects the price of steel bar electric induction furnace. In addition, the configuration of the steel bar induction heating furnace is the same. If a set of steel bar heating furnaces is equipped with many advanced configurations and plays a greater role in the machine, the price will be much higher.

To sum up, the medium frequency induction heating furnace is an electric induction furnace that uses the principle of electromagnetic induction to heat metal, which is widely used in high-temperature heating and low-temperature heating, forging industry, casting industry, and metal quenching and tempering heating in high-temperature heating, and steel pipe anti-corrosion spraying preheating in low-temperature heating. The medium frequency induction heating furnace has become indispensable heating equipment.

cement grinding machine selection: vertical roller mill vs roller press

cement grinding machine selection: vertical roller mill vs roller press

Grinding machines are indispensable equipment in cement plants. In the process of cement production, the cement plant needs to complete the grinding of pulverized coal, raw meal powder, and cement products. The purpose of grinding is to increase the specific surface area of the material and reduce the particle size of the powder, so as to achieve the activity required by the next process.

Tube mill has been used as the main grinding equipment in the cement industry for a long time, and it is still widely used because of its simple structure, easy operation, and low price. However, the energy utilization rate of tube mills is only 2% ~ 20%, which is very low. With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press.

Both the vertical roller mill and roller press apply the working principle of material bed milling. During the grinding process, only a small part of material particles directly contact with the grinding parts of the mill; but under the action of grinding parts, material particles form a material bed, and through the stress transmission and interaction between the particles, they are cracked, broken, and crushed.

For vertical roller mill, the grinding parts are rollers and grinding disc. The pressure required for grinding mainly comes from the rollers. At present, the loading force is mainly formed by hydraulic pressure. The material is fed into the grinding disc from the center or side of the upper housing, and the material layer is formed in the process of moving on the grinding disc. When the material passes between the roller and the grinding disc, the grinding is completed under the extrusion and shear force between them.

For roller press, the grinding parts are two rollers of the same size. The materials fall vertically from the top to the two rollers to form the material bed. Under the extrusion force of the two rollers, materials are ground to fine particles. There are two transmission modes of roller press, namely double drive, and single drive. The double drive roller press is the more popular type. The transmission device of a single drive roller press has only one set to drive one roller, and the other roller is driven by connecting with the former one with a gear train.

In a vertical roller mill, the material on the grinding disc is restricted by the air duct ring, but the side of the material between roller and disc is not restricted. In roller press, in addition to the restriction between the two rollers, side baffles will also be set on the sides of both ends of the roller, which will limit the side of the material bed of the roller press.

Because the grinding area of the roller press is restricted from all sides, the increase of applied energy will also increase the fine powder and specific surface area of material. But for vertical roller mills, the growth rate of that of material will gradually decrease. From this point of view, roller press is superior to vertical mill.

In a vertical mill, there generally are two or more grinding rollers. The contact area between the grinding roller and the grinding disc is large, and the energy utilization rate is higher than that of the roller press. Moreover, the materials are generally milled on the grinding disc by several grinding rolls repeatedly. From this point of view, the vertical mill is better than the roller press.

When grinding cement products, a grinding system composed of a roller press or an external circulation vertical mill + a powder concentrator + a tube mill is generally selected. Taking grinding P o42.5 cement as an example, the pre grinding closed-loop system composed of roller press or external circulation vertical mill and powder concentrator has a circulation load rate of 200% 300%, and the specific surface area of the selected materials is 180-280m2 / kg. The following table lists the main machine preparation and the product particle size of several cement grinding systems.

The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers. When the material is ground to a certain fineness, most of the fine powders from the vertical mill are irregular and prismatic, and the fine powders from the roller press are mainly irregular flake and strip particles. From the particle shape, the fine powder from vertical mill is closer to that from tube mill, and the fine powder from vertical mill is more suitable for making cement products than that from roller press.

roller mill: components, designs, uses, advantages and disavan

Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials. One of the rollers is run by a motor and the others are rotated by friction as the material is drawn through the gap between the rollers.

Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap.
