Micro Powder Mill is also called high pressure micro powder mill, which is a highly efficient powder grinding machine manufactured on the basis of high-pressure grinding mill and improving the classification technology of the fineness of the final products. This machine technically solves the difficult problem of the classification of superfine powders, thus greatly improving the classification efficiency while ensuring the grinding quality and output. The finished products granularity of grinding machine has a wide range, the largest diameter of particles can reach to 30 mesh, the general diameter of particles is up to 0.033 millimeter (425 mesh). The finest small amount of material can reach to 0.013 millimeter (1000 mu).
When entering grinding chamber, the raw materials are shoveled up by the shovels and grinded between the rollers and ring; the materials after grinding are brought into the separator along with the air from the blower, and the qualified fine powder became final products and come into the cyclone powder collector, the other unqualified powder fall down to be re-grinded. The circular air returns back to the blower that the above process will be repeated, and the remaining air enters the bag filter in order to protect the environment.
1. Compared with other mills, its capacity increases by 10%-20% under the same power condition, and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.
2. Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
3. Machine for Limestone Powder mill/High pressure grinder mill meets the requirement of national dust-dump standard.
4. The separator can be adjusted very easily.
5. The multi-class seals are adopted to keep the grinding equipment tightly closed.
