ultrafine powder grinding & classifying technology - expert in high-value treatment of calcium carbonate

The processing of ground calcium carbonate is simply the process of using crushing and grinding equipment to process calcium carbonate minerals into various powders that can meet the requirements of industrial applications. Because different industrial applications have different requirements on the particle size, shape, whiteness and particle size distribution of ground calcium carbonate powder, the processing technology of ground calcium carbonate should also comprehensively consider the process route and equipment selection according to the product positioning. Generally speaking, the design of grinding equipment is based on different principles: impact, extrusion, friction, shear and combination of various forces, etc. Different designs will have different grinding effects and product fineness.

The common processing equipment of ground calcium carbonate produced by large-scale dry process includes Raymond mill, Vertical mill, Ring roller mill and Ball mill. Due to the different crushing principle and discharging method of the equipment, the processed powder has great differences in grain type, particle size distribution and unit energy consumption, so the positioning of the product also has obvious differences.

The ball mill can cooperate with the air classifier to form a closed-circuit circulation system, after the grading of the coarse powder can be returned to the ball mill for re-grinding, and the Raymond mill, vertical mill, vibration mill due to the capacity of the mill is very limited, return difficult, unable to form a closed-circuit circulation system, to return to the treatment of problems.

The ball mill is also a low speed operating equipment, impact and friction energy consumption to minimize. Therefore, it is not only an ideal choice for grinding high hardness, abrasive mineral raw materials, but also the most economical choice for grinding white filler minerals such as low hardness calcium carbonate.

It can be seen from the particle size distribution map that the particle size distribution of the grinding products of the ball mill is the widest. Through the air classifier, the products with different fineness requirements can be separated. At the same time, the output of the ball mill is large, with scale effect, so it has a strong market adaptability and competitiveness.

The production line adopts the international popular continuous production process: ball mill and air classifier system. The technological process mainly includes crushing (generally using two-stage crushing), grinding, classifying, packaging, magnetic separation, transportation, lifting, etc. After the ball mill can be parallel or series multiple classifier at the same time to produce more than one size of the product.

Working principle: The raw material is fed into the hollow cylinder through the hollow shaft neck for grinding. The cylinder is equipped with grinding media of various diameters (steel ball, steel bar or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, the medium and raw materials in the cylinder under the action of centrifugal force and friction force, as the cylinder reaches a certain height, when its own gravity is greater than the centrifugal force, it will escape from the cylinder body wall and drop or roll down, smashing the ore due to the impact force. At the same time, the sliding motion of the grinding medium also produces grinding effect on the raw material during the rotation of the mill. The ground material is discharged through a hollow journal.

Raymond mill is the earliest and most widely used grinding equipment in China, with low fineness, suitable for the production of 400 mesh of coarse ordinary powder. A small amount of 500 ~ 1250 mesh products can be obtained through secondary classification. Suitable for large scale production of coarse powder and small scale production of fine powder.

Working principle: Raymond mill rollers works under the action of centrifugal force tightly on the ring rolling, the shovel knife scooping up material to the grinding roller and grinding ring in the middle, the material under the action of ground pressure, broken into powder, and then under the action of fan blow into powder material up through analysis of machine, to fulfill the requirements of fineness of materials through the analysis of machine, cant meet the requirements of the return to continue to grinding, grinding chamber through the analysis of the material into the cyclone separation of machine to collect. Use industrial press cloth to separate the air exhaust into powder.

Vertical mill is a typical material layer extrusion crushing equipment, the most fine can reach 1250 mesh, through the second, third classification of the most fine can reach to 3000 mesh, generally suitable for mohs hardness of less than 7 materials.

Working principle: The motor through reducer driven in mill, material from the feed opening fell into a grinding disc, move to the edge of mill under the action of centrifugal force and grinding roller of roller compaction, shredded material from mill edge overflow, at the same time from the nozzle ring (ring) wind speed up stream to efficient separator, which is one with vertical mill meal after separator is returned to the mill wheel, grinding again; The fine powder is ground with the air flow and collected in the dust collecting device of the system, which is the product. Coarse granular materials not taken up by the hot gas flow and accidental entry of metal parts sink from the wind ring, after scraping out by the scraper, through the external circulation of the bucket machine feeding into the grinding again grinding.

As the roller is small and many, the fit clearance with the grinding ring is also small, the most fine grinding can be up to 2500 mesh. Low energy consumption and low fine powder content. Generally suitable for mohs hardness below 5, narrow particle size (low oil absorption value), moderate fineness of materials. But forhard materials, if they are light color (white), the degree of dialogue has a great influence.

Working principle: It adopts the principle of impact, extrusion and grinding to crush the material. There is a large active gap between the grinding ring and pin shaft installed on the grinding ring bracket. When the grinding ring bracket rotates with the spindle, the grinding ring is swung to the grinding ring by centrifugal force, and the inner wall of the grinding ring is pressed and rotates around the pin axis. When the material passes through the gap between the grinding ring and the grinding ring, it is impacted, squeezed and ground by the grinding ring. Under the action of gravity, the crushed material falls into the swing plate and is then thrown into the air flow into the grading chamber for classification. The qualified fine powder is collected through the grading wheel into the rear passage collection system, and the coarse material is thrown into the shunt ring for internal avoidance, and then falls back into the crushing chamber for crushing. The grinding ring is single layer or upper and lower double layer distribution. When the double-layer grinding ring crusher works, the material is crushed again when passing through the gap between the second grinding ring and the grinding ring.

minerals engineering conferences - ultrafine grinding 06

minerals engineering conferences - ultrafine grinding 06

What is ultrafine grinding and what role can ultrafine grinding play in the minerals industry now or in the future? This theme attracted representatives from equipment manufacturers, suppliers of grinding media, mining companies, consultants and academics to a conference in the seaside resort of Falmouth in Cornwall, UK (12-13th June 2006). The conference was attended by 64 delegates from 24 countries spread across all five continents.

While the concept of grinding minerals hardly requires an introduction, it emerged that the definition of ultrafine particles depends on the application: it can relate both to particles in the low m size range and to particles which have been considerably reduced in size. Traditional barriers to ultrafine grinding are the relatively high energy requirement and a perceived reduction in efficiency during further processing. However, technological advances in ultrafine grinding may be welcomed by the mining sector, where the necessity to process increasingly complex ores is presently coupled to buoyant commodity prices.

While conventional milling techniques may produce an ultrafine grind, the required energy rises sharply as the product size, often characterized in terms of the 80 % passing size, d80, decreases. Ultrafine grinding techniques are those techniques which are more energy-efficient than conventional milling techniques in the sub 100 m range. Other advantages over conventional techniques are the option to avoid contamination of the product with ferrous chips, for example from steel balls used as grinding media, lower wear for ultrafine applications, the ability to contain dust and manage heat generation. On the downside, D. Yan states that ultrafine grinding techniques are less predictable than conventional ball mills in terms of energy requirement and grinding performance while throughput may be limited.

During ultrafine grinding, particle breakage occurs by familiar mechanisms: impact or attrition by shear or a combination of these. Classic examples of impact techniques are jetmills where particles are either accelerated against a surface or against other particles moving in the opposite direction. While impact techniques are not suitable for breaking relatively tough materials such as quartz, modified jetmills may be useful for some tough applications. J. Roth (PMT-Jetmill) presented the spiral jetmill as an alternative to classic jetmill designs. The feed is injected into the milling chamber through tangential nozzles while the product is recovered through the classifier rotor located in the middle of the milling chamber. Intense shear between the particles in the milling chamber can produce delamination, preserving or even increasing the aspect ratio of particles. This is beneficial, for example, when talc is ground to enable separation of quartz prior to its application as a reinforcing filler in plastics. In another example, B.G. Kim added that it is attractive to preserve the flaky shape of graphite particles during ultrafine grinding in view of their high conductance.

A. Mc Veigh (Hicom International) discussed application of the Hicom mill for enhancing the recovery of kaolin from china clay waste minerals (silica and mica). Kaolin is commonly used a filler in paper, with platy kaolin enabling the production of lighter and smoother paper. In the Hicom mill, grinding is induced by the inability of the feed to follow the nutating motion of the milling chamber. Product particles escape through openings in the grinding chamber. The Hicom mill can be operated with or without the addition of grinding media. Using relatively fine grinding media, the Hicom mill achieved better delamination than a sand mill currently used by a china clay producer.

Evidence of high-intensity grinding in a Hicom mill was also observed by M. Thornhill, who ground potassium feldspar concentrates with a view to increasing the availability of potassium and assessing their potential as a fertilizer. Trials suggested that ultrafine grinding irreversibly increased the leachability of potassium, although a lower limit to the particle size was observed: very fine particles tended to agglomerate, reducing the specific surface area and the associated leachability of potassium. Comparison with ultrafine grinding of a potassium-rich nepheline syenite concentrate suggest that the effect of mechanical activation achieved by ultrafine grinding is mineral-specific. Although mechanical activation is a difficult concept, E. van der Ven pointed out that ultrafine metal powders can be hazardous on account of their extreme reactivity.

A. Mizitov (Oy Microworld) described the grinding action in a uniRim mill as the equivalent of a pestle-and-mortar. Grinding in the uniRim occurs between the cooled mantle of the grinding vessel and grinding blocks attached to a central rotor. Grinding also occurs well away from the rotor in a planetary mill, which consists of independently-rotating canisters located at the end of arms extending from a central rotor. The combination of centrifugal acceleration of particles towards the rim of the canisters and the even higher angular velocity of the canisters creates a high-intensity grinding environment. E. Kuznetzov (Cyclotec) provided a video to suggest that previous issues such as heat and dust generation, mechanical integrity and discontinuous discharge had been resolved. Scale-up to 100 t/hr is expected to be feasible.

M.K. Abd El-Rahman (CMRDI) studied ultrafine grinding of a variety of minerals in a planetary mill as a function of the rotation speed of the canisters and the presence and size of grinding media in the canister. The advantage of higher rotation speed levelled off at higher speeds, possibly due to cake formation on the canister mantle, while degradation of grinding media increased. Relatively fine grinding media initially led to reduced particle size reduction but, for prolonged grinding, enabled attainment of a smaller product size. This is thought to be due to the smaller interstitial space between media particles, which are generally much larger than the size of product particles. Perhaps surprisingly, a relatively low grinding media-to-feed ratio appeared to increase the initial rate of particle size reduction. For further improvement of grinding performance, the use of chemical additives acting as dispersants was deemed promising.

While stirred media mills stem from a fairly basic design, they have been subject to extensive further development and refinement. For example, the MaxxMill developed by Maschinenfabrik Gustav Eirich consists of a vertical rotating vessel which contains one or more eccentrically-positioned rotors and flow deflectors. Because the MaxxMill operates in dry mode, the smallest particles can be sucked out and classified in an auxilliary cyclone. Particles above a maximum tolerated size are returned to the mill, enabling control of the product size. S. Gerl (Gustav Eirich) presented options to integrate the MaxxMill into processes.

Maelgwyn Minerals Services' M. Battersby introduced the Deswik Turbomicronizer (TM) Mill, a high-speed stirred media mill with a series of impellers along the central shaft. Having evolved from a horizontal design, the vertical Deswik TM Mill is less sensitive to failures of bearing seals and blocking of screens. Feed material is introduced as a slurry at the bottom of the mill, moving upwards in a helix-type flow pattern along a hard-wearing polyurethane resin mill lining. Grinding media are recycled internally to the base of the mill.

Given the technological advances, the focus is turning on the reliability and availability of ultrafine grinding technology in a mining environment. Stirred media mills are starting to feature in large-scale commercial mining applications. Following K. Barns' introduction of the five key process technologies marketed by Xstrata Technology, the application of IsaMill for ultrafine grinding was discussed by D. Curry. Lead/zinc ore at the Mc Arthur River mine in Northern Territories, Australia, requires grinding the ore to below 7 ?m in order to achieve sufficient liberation of galena and sphalerite. Compared to conventional grinding, ultrafine grinding was reported to increase the zinc recovery by 10 %. The IsaMill, which has been developed in partnership with Netzsch Feinmahltechnik, is a high-intensity (up to 300 kW/m3) horizontal disk mill with 8 grinding chambers in series. While media are present to enhance the grinding process, media is retained in the mill without the use of screens. The product is reported to have a narrow particle size distribution, which is considered to be a key factor in maintaining efficient downstream flotation. Using d80 as a parameter, IsaMill may be scaled up, as witnessed by a 3 MW unit being commissioned for AngloPlatinum at Potgietersrust, South Africa.

Anglo Platinum already operates a 2.6 MW unit at Rustenburg, South Africa, for tailings re-treatment, aiming to recover Platinum Group Metals (PGM). C. Rule (Anglo Platinum) explained that ultimate recovery of PGMs locked up in silicates depends on enhanced liberation brought about by ultrafine grinding. A notable improvement in PGM recovery is observed when grinding more tailings below 75 ?m. Anglo Platimum's experience with IsaMill suggests that the wear of mill lining and media consumption were lower than predicted for this application and that the product size distribution and energy consumption were within specification.

The generally advanced nature of stirred media mills was confirmed by the laboratory-scale investigation of two ultrafine grinding techniques by J. Parry. Aiming to liberate fine galena in coarse sphalerite present in ore from Red Dog mine, both the IsaMill and the Stirred Media Detritor (from Metso Minerals) achieved comparable results, as measured with the Mineral Liberation Analyser (from JKTech).

Besides developments in the design and scale-up of stirred media mills, a significant technological breakthrough was achieved with the introduction of a new class of grinding media. Previously, typical grinding media, such as the ore itself, slag, silica sand or river pebbles, suffered from lack of quality, notably inconsistent size and competence. According to P. Hassall (St Gobain-Zirpro), the advent of manufactured media lead to substantial improvement of the media quality through a uniform chemical composition and a high hardness, sphericity, roundness, density, and competency. As a result, the grinding efficiency increases and the energy consumption is lowered. The modern media are typically manufactured ceramic materials such as aluminium oxide, yttrium-, cerium- and magnesium-zirconia oxides and various silicates. B. Clermont (Magotteaux International) described that Keramax MT1 media, containing a mixture of oxides, lowered the energy consumption because there was less sliding friction between hard, spherical media particles. G.A. Graves (Zircoa) emphasised that the smooth surface of media particles, a narrow media size distribution, a high hardness and fracture toughness are vital to achieve energy consumption reduction. Image analysis may be used to monitor the shape and size of media particles. It should be noted that determination of the optimum size of media particles for a given application requires careful consideration. While an application may require media with various media particle sizes, there may be a case for staged milling and ultrafine grinding with optimized media sizes.

While ultrafine grinding can improve recovery and reduce downstream reagent requirements, the effect of extra particle size reduction should be balanced by the cost of additional grinding energy. For example, the Deswik TM Mill reduced a feed with d90 of 89 m to 20 m with 10 kWh/t or 12 m with 16 kWh/t. Ultimately, the economics will decide whether the application of ultrafine grinding will continue to grow.

fly ash processing plant - cement equipment manufacturing - agico

fly ash processing plant - cement equipment manufacturing - agico

Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged from coal-fired power plants. Its annual output is large, which has great harm to the environment and human health. And its particle distribution is very uneven, so it usually needs to be ground to improve its performance to be put into secondary use. As a kind of industrial waste, fly ash is rich in resources, low in price, and contains a lot of active ingredients. After classifying and grinding, it can replace clay to become the raw material for producing cement clinker, and can also be used as an admixture of concrete to save a lot of cement and fine aggregate. The fly ash processing plant constructed by AGICO Cement is highly automated and mechanized, with low investment, high profit, simple structure and easy operation, which helps each region realize reasonable waste recycling and utilization to green up users supply chains.

The first step of the fly ash processing system is taking ash from the silo and sending it into the elevator in front of the grinding mill after feeding by the feeder and electronic weighing. Then the fly ash will be fed into powder concentrator for the first classifying. During the classifying, qualified fine ash enters the fine ash silo through conveying chute, while the coarse ash is sent to the cementball mill for fine grinding. After grinding, the pulverized fly ash needs to be classified again in the powder concentrator. The fine ash that meets the requirements is sent to the fine ash silo through the conveying equipment, and the coarse ash is sent back to the ball mill for secondary grinding. The whole system is equipped with a dust collector. There is no need to worry about dust pollution.

This fly ash classifying system is developed by our researchers according to years of practical operation experience. It is a closed-circuit circulation classifying system with high efficiency and adjustable turbo-type powder concentrator as the main equipment.

After grinding, the fly ash can be used as a partial substitute for concrete raw materials. Different incorporation of fly ash will affect the hardening level, strength, dry shrinkage and other characteristics of concrete, with an ideal content of 40%. Using fly ash as raw material to make cement has been quite common in cement plants, and the technology is relatively mature. The ideal content can reach 75%.

Fly ash, aggregate, cement and other raw materials can be made into different types of concrete blocks through batching, mixing, molding, curing and other processes, such as fly ash concrete hollow block, fly ash brick and so on.

High purity alum can be extracted from fly ash to synthesize bauxite. Making fly ash as raw material, SiC powder, a non-oxide ceramic material, which is widely used in the market, can be synthesized by carbothermal reduction synthesis method. The fly ash can be made into polymer filling material after some refinement processing.

Fly ash is rich in microelements, such as silicon, boron, sulfur, zinc, copper, calcium, magnesium, iron, etc. It has loose texture and can improve the soil structure. If we mix some additives with fly ash according to a scientific formula, we can make compound fertilizer.

AGICO Group is an integrative enterprise group. It is a Chinese company that specialized in manufacturing and exporting cement plants and cement equipment, providing the turnkey project from project design, equipment installation and equipment commissioning to equipment maintenance.

comparative comminution efficiencies of rotary, stirred and vibrating ball-mills for the production of ultrafine biomass powders - sciencedirect

Greater process efficiency when the milling device is suited to the biomass.Milling that combines impact and attrition is more flexible and effective.Milling that generates attrition efficiently yields fine biomass particles.Agglomeration of fine particles significantly influences milling efficiency.

Plant biomass as a substitute for fossil oil is one of the most promising pathways to reducing the environmental impact of human activities. Ultrafine comminution of plant materials can produce ultrafine powders suitable for direct use in advanced-technology applications as an engine, becoming a sustainable powdered biofuel. However, comminution is an extremely energy-intensive process, making it vital for industry to select the most efficient milling device for the biomass. Here, we comprehensively compared the efficiencies of three batch ball mills employable for ultra-fine comminution of plant materials. First, we led a ball motion study to estimate the predominant mechanical stresses generated by each device. Two biomasses with contrasted physical properties were milled using three devices to achieve a target particle size of 20m. Milling times and process energy consumption were recorded, and the particle size distributions and specific surface areas of the ground powders were measured. The balls mills were then compared based on several indicators of energy efficiency, productivity and processing speed. The results show that the energy input is better utilized in mills that work by attrition or by combined impact and attrition.
