Steel slag vertical roller mill-important equipment in the steel slag grinding plant As is known to all, in the industrial industry, steel slag is a solid waste that is poorly utilized by steel companies. Except for extracting some of the metal iron, most of them are not effectively utilized. Most steel plant have not fully utilized steel slag after fully selecting iron. They contain higher divalent metal ions than cement clinker and have a large space for utilization. A large amount of residual micron-sized metal iron particles can cause magnetic agglomeration and magnetic adhesion in the steel slag grinding plant, making ultrafine grinding impossible. Therefore, in order to carry out ultrafine grinding of the steel slag, the exposed metal iron particles must be removed in time during the grinding process. GRMS steel slag vertical roller mill is a new type of ultra-fine vertical mill designed and developed by Xinxiang Great Wall after decades. It uses a large amount of external circulation and effectively removes iron in the outer circulation. It can choose about 1.5% iron in the tailings. At the same time, the steel slag powder produced is high in fineness, and the specific surface area of the finished product can reach 450~500 m2/kg or more, and the activity is good, and it is suitable as cement active mixed material and concrete admixture. Regardless of the fineness of the finished product, power consumption or investment cost, the steel slag vertical mill of Xinxiang Great Wall can meet the requirements of users.

The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process. In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.
The VRM cement mill has a more complex structure than other types of cement mills, so we need to ensure the following aspects are normal during the operation, or the machine may not be able to function well.
Too thick material layer will reduce the grinding efficiency of the vertical roller mill. When the pressure difference of the mill reaches the limit, the material layer will collapse and affect the operation of the main motor and the discharge system.
There are many factors that may make mill body vibrate, including the grinding pressure, material layer thickness, air volume and temperature, accumulator pressure, wear condition of the roller and the grinding plate, etc.
The grinding pressure of the mill should be adjusted according to the fed quantity, the particle size, and the grindability of the material. It must be well controlled to maintain the thickness of the material layer, reduce the vibration of the mill body, and ensure that the stable operation of the mill.
Increasing the grinding pressure will improve the grinding capacity of the mill, but the grinding capacity will stop increasing when the grinding pressure reaches a certain critical point. If the set pressure of the hydraulic cylinder is too high, it will only increase the driving force and accelerate the wear of parts, but not improve the grinding capacity.
On the other hand, too high grinding pressure will cause the thickness of the material layer to decrease, which further leads to the increase of the vibrating speed of the mill and accelerates the wear speed of the parts.
The gas temperature at the discharging port can be increased by increasing the opening of the hot air door and reducing the opening of the circulating air door. However, when the gas temperature exceeds 130 , the equipment will also be damaged. For example, the dividing wheel at the lower part of the cyclone will expand and get stuck, and the lubricating grease of the grinding roller will dry and crack, which is also unfavorable to the tail dust collection bag.
In vertical roller mills, the air volume in the mill is determined by the material feed rate. The air volume can be controlled by adjusting the power of the circulating fan of the mill or the opening of the exhaust fan at the kiln tail.
If the air volume is too large, the pressure difference in the mill and the current of the main motor will decrease, the thickness of the material layer will become thin, and the vibration degree of the mill body will become strong.
If the air volume of the system is too small, the thickness of the material layer, the pressure difference in the mill, and the current of the main motor will increase, and so will the vibration speed of the mill.
When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln.
Slag powder is high-performing admixture for concrete in that it increases the concretes ability to resist compression, tension, shear, and bending stresses. A major trend that characterizes the building material industry is to replace equal amount of cement with slag powder in making concrete or cement products.

Over the last three decades the vertical roller mill has be widely used in cemment industry. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
Since the 1980's, cement plants are increasingly looking to vertical roller mill technology for their finish grinding needs. Vertical roller mills present a compact and efficient grinding method. Vertical roller mill in cement industry has various forms, there is a cylinder, cone type, ball type, etc., and roller surface is also flat, curved, convex round noodles. Applied to the grinding roller to roller grinding along the track bed in close contact with the material strength of a spring pressure, hydraulic, etc.
Cement manufacturing is a complex process, it is simple to say is that the clinker and gypsum is ground on a rotating table that passes under large rollers. Material is forced off the table by centrifugal force, where it is then swept up into an airstream to a classifier immediately above. Just as with a ball mill, material that is too coarse is returned to the table for additional grinding while material that is fine enough is collected as product. The compact design of a vertical roller mill allows it to dry, grind, and classify, all within one piece of equipment and all in a relatively compact space.
In cement industry, vertical roller mill is the most important equipment. In the 70s, vertical roller mills became increasingly dominant for grinding raw materials mainly for the cement industry due to their high energy efficiency and excellent drying capacity.

Cement mills are the milling machines used in cement plants to grind hard clinker into fine cement powders. Cement ball mill and vertical roller mill are two most widely used cement mills in todays cement grinding plants and are also the main types of cement mill we produce.
As a professional cement equipment manufacturer, AGICO has rich experience in the designing and manufacturing of cement ball mills and vertical roller mills. Our cement mills have extraordinary performance in the cement grinding process of the new dry process cement plants.
The cement ball mill is mainly composed of a horizontal cylindrical shell, feeding & discharging hollow shafts, liner plates, and grinding media. The mill body is a long cylinder, with many grinding balls inside. The cylinder is made of steel plate, and the inner part of the cylinder is fixed with steel lining plate; the grinding balls are steel balls with different diameters, which are installed into the cylinder in a certain proportion. There are also ball mills that use steel segments instead of steel balls as grinding media.
There are two chambers in the cement ball mill. When the ball mill is operating, the clinker is fed into the first chamber in the cylinder body through the hollow shaft at the feeding end of the mill. When the cylinder rotates, the grinding balls, under the action of inertia, centrifugal force, and friction force, clings to the lining plate inside the cylinder and rotates with it. When they are brought to a certain height by the lining plate, they will be thrown down due to gravity, and the clinker in the cylinder will be smashed.
After coarse grinding in the first chamber, the clinker enters the second chamber through the single-layer partition board. The second chamber is inlaid with a flat-lining plate and steel balls, which further grind the material into cement powders. The powders are finally discharged through the discharge grate plate, and the cement grinding operation is completed.
Vertical roller mills (VRM) are a type of mainstream clinker grinding equipment in the cement manufacturing process. Vertical roller mills are still newish cement mills since their history in cement production is no more than 20 years, but they have already become the standard cement equipment in many regions and are getting more and more popular among cement producers.
When the vertical mill works, the motor drives the grinding disc to rotate, and the grinding roller rotates around the grinding roller shaft driven by the disc. The material entering from the feeding port falls in the center of the grinding disc and moves towards its edge under the action of centrifugal force. When the material passes through the grinding track, it is meshed between the roller and the disc and crushed by them. After grinding, the material continues to move towards the edge of the disc until it overflows. An air duct ring is installed around the grinding disc, from which the hot air flows out at high speed from bottom to top, and carries the spilled materials. The material with large particles will fall back to the grinding disc, and the material with small particles will be brought into the powder concentrator for coarse and fine classification. The coarse powder falls back to the grinding disc for regrinding, and the fine powder meeting the requirements is sent out as the finished product, which is collected by the dust collector at the upper outlet along with the airflow.
