The chalk micro powder mill is independently developed and produced by SBM. It mainly includes 3 types, namely HGM ultrafine grinding mill (150-3000 meshes), CLUM vertical mill (150-3000 meshes), and wet stirring mill (325-6000 meshes). They can grind non-metallic ores, and the fineness can be adjusted freely according to demand.
Because of the difference in working principle, their output and the shape of the finished powder are also different. So if you need an ore micro powder mill, you can contact us directly. Our professional technicians will recommend the most suitable industrial ore grinding mill based on your raw materials, production requirements, and finished powder applications.
In addition, in addition to an ore ultrafine grinding mill, we can also configure a complete production line for you, including stone crushers, elevators, dust collectors, balers, powder surface modifiers, and other equipment.
Chalk is loose earthy calcite or limestone, the main chemical component is CaCO3, and the main mineral component is biological micrite calcite. For those with a purer texture, the calcite content can reach more than 99%. It often contains impurities such as quartz, feldspar, clay minerals, and sea green stone.
According to the color and degree of cementation, chalk can be divided into four types: white chalk (CaCO3 content reaches 99), marl chalk, chalk-like limestone, and glauconite chalk.
The chalk is white in color and highly dispersible. The particles are round in shape, fragile, and have little water absorption. Poor cementation, easy to crush, and strong coating ability.
Chalk is widely used in rubber, paper, paint, plastics, pigments, coatings, ceramics, sugar, casting, as well as grease, sealants, etc.
As a mineral, chalk is generally used to make white paint, chalk, and other products. Before application, it needs to be crushed and ground to obtain chalk powder. Chalk production process equipment includes a vibrating feeder, jaw crusher, micro powder mill, hoist, conveyor, etc.
So how to make chalk powder?
Crushing stage: Large pieces of material are crushed by the crusher to the fineness of the feed material (10mm-25mm) that can enter the ultrafine grinding mill.
Grinding stage: Small pieces of material that meet the conditions for entering the mill are uniformly and quantitatively fed into the grinding chamber of the mill through the conveying and feeding system, and pulverized in the grinding cavity.
Classification stage: the ground material will be classified by the classifier along with the airflow of the system, and the unqualified powder will be classified by the classifier and returned to the main machine grinding cavity for re-grinding.
Powder collection stage: The powder that meets the fineness enters the powder collection system through the pipeline with the airflow, and the gas and powder are separated. The finished powder is sent to the finished product silo by the conveying device and then is packaged by a powder tanker or an automatic baler.
The equipment needed for the chalk processing process includes jaw crushers, bucket elevators, storage bins, vibrating feeders, micro powder mills, powder classifiers, powder collectors, pulse dust collectors, high-pressure fans, electrical control systems, etc. The chalk is crushed by a crusher, pulverized into powder by an ultrafine grinding mill, and then powdered by a powder separator. The fine powder that meets the requirements is the finished product and is discharged through the discharge valve.
Jaw crusher >>
Jaw crushers are widely used as crushing equipment in the chalk grinding production line. It is mainly used for the primary crushing operation of the raw material chalk so that the crushed chalk meets the particle size requirements required by the next construction. The equipment has the characteristics of a small footprint, simple operation, convenient maintenance, large processing capacity, energy-saving, and consumption reduction.
Micro powder mill >>
The application of chalk powder in various fields has different fineness requirements. Common ones are 200 mesh, 325 mesh, 600 mesh, 800 mesh, 1250 mesh, and above. According to different needs, the most suitable grinding mill machine can be configured to achieve the best benefits.
— 150-3000 mesh powder —
The micro powder mill adopts a newly designed grinding roller grinding ring grinding curve, which improves the grinding efficiency. The production capacity is 40% higher than that of jet mills and mixers, and the energy consumption is only 30% of that of jet mills.
HGM micro powder mill is equipped with a multi-head cage type powder separator. The fineness of the product can be adjusted arbitrarily between 150-3000 mesh, and the one-time screening rate can reach d97≤5μm.
The lubrication device is installed outside the main shaft, which is convenient for maintenance and can realize external non-stop lubrication and 24-hour continuous production.
HGM micro powder mill is equipped with a high-efficiency pulse dust collector, so there will be no dust pollution during the operation of the entire crushing system.
SBM specially designed a unique roller shell and liner grinding curve, which can greatly improve the working efficiency of the mill and improve the whiteness and cleanliness of the finished product.
Using a PLC control system and multi-head powder selection technology, it can precisely control the working parameters of the equipment such as grinding pressure and speed. Compared with ordinary mills, the energy consumption of this mill can be reduced by 30%-50%.
The contact point between the roller shell and the grinding disc liner adopts electronic limit technology and mechanical limit protection technology, which can avoid the destructive impact caused by machine vibration and ensure the stability of operation.
Through the reversible structure and hydraulic adjustment system, the operator can easily and quickly move the grinding roller out of the machine body, inspect and replace the roller shell and liner, and perform other maintenance operations to reduce downtime losses.
— 325-6000 mesh powder —
Ultrafine powders, reach 2 microns with a content of 90% for milling one time.
Has a large output, high efficiency, low energy consumption, environmental protection, and other features.
Vertical-shaped star wheel reducer higher transmission efficiency, run more smoothly.
Low consumption of grinding media, non-polluting. The temperature is low for finished products, good liquidity.
Compact structure, suitable height, easy operation and maintenance, stable production, automatic controlling is optional.
Electromagnetic vibration feeder >>
The electromagnetic vibrating feeder is mainly used to evenly feed the chalk into the receiving device. The equipment has the characteristics of small size, lightweight, convenient maintenance, low operating cost, and low wear of the feeding trough. It is a piece of very good feeding equipment.
Bucket elevator >>
Bucket elevator is a kind of vertical lifting equipment, which sends chalk vertically to the equipment needed in the next step. The equipment has the characteristics of reliable operation, large conveying capacity, low maintenance, and few wearing parts.
