Roller Mill SRM

Product Description

　　Compared with traditional mills such as ball mills, impact mills, and jet mills, ultra-fine ring roller mills have proven to be the most efficient dry mills. Originally aiming to realize non-metallic mineral grinding with lower energy consumption than ball mills, its application has now been expanded to other industries such as fine chemicals, building materials, and high-tech new materials.

　　Application materials: calcium carbonate (limestone, marble, chalk), dolomite, gypsum, talc, barite, gasoline cola, battery materials, activated carbon, carbon black from pyrolysis waste tires

Product Feature

　　1. It is suitable for fine powder grinding of most materials with Mohs hardness less than 6.

　　2. The product has a wide range of fineness, ranging from 200 mesh to 2500 mesh.

　　3. The top integrated high-precision powder classifier ensures good product fineness. The particle size distribution of the finished product is adjustable.

　　4. In most cases, it has lower energy consumption than other types of mills such as ball mills, impact mills, jet mills, etc.

　　5. The investment cost is lower than that of a ball mill, and the installation space is small.

　　6. Conducive to heavy grinding and low maintenance. Key components such as rollers and rails are made of wear-resistant materials.

　　7. Optimized structural design, convenient replacement of key components, and shortest downtime.

　　8. Intelligent PLC control system, simple operation and stable production.

Principle

　　1. The ultra-fine roller mill system mainly includes raw material warehouse, raw material feeder, roller mill, cyclone collector (optional), bag filter, suction fan, and control cabinet.

　　2. The bottom of the roller mill is a roller mill system, and the top is a turbine grading system. The roller mill system has 3-4 layers of rollers. The turbo classifier has a classifying wheel installed vertically on the top.

　　3. The raw materials enter the mill from the top and are distributed on the surrounding rollers. When the raw material passes through the gap between the roller table and the grinding rail, it is impacted, squeezed and ground into fine powder. When the material passes through 3-4 layers of rollers from top to bottom, it is thrown to the shell wall and carried by the suction airflow to the classifying wheel. Qualified fine particles pass through the gap between the blades of the classifying wheel and fly out from the top of the mill along with the inhaled air flow; excessively large particles are rejected under the centrifugal force of the high-speed rotating classifying wheel, and fall into the first layer of rollers. The feed is mixed and further ground.
