As a high quality raw material of making coal water slurry and coal based material, the requirement of ultra-coal has a great demand as well as the making craft becomes more important. The ultrafine grinding technology is a newly grinding technology in recent 20 years, which is used in ultrafine processing and improving of materials, which the grinding product is called ultrafine powder widely used in chemical, micro-electronic, healing drugs, material, etc. Because of the difference of industry, application and devices, the ultrafine granularity has different limits. But the common device used in coal selection device is ultra-mill and fine mill, etc.
After the material’s ultra comminuting, the surface become larger and the monomer volume become smaller with some extinct secularity such as better dispersity, absorbability, surface activity, low melting point, high ferromagnetism, etc. In the ultra-coal equipment, to ensure the full dissociation of coal and mineral, the granularity often becomes very fine, specifically determined by the secondary mineral. C&M Mining Machinery has many patents on mill machine. After the improvement of Raymond mill, high pressure roller mill, ultra pressure trapezium mill, etc appears rapidly.
Coal mill produced by C&M Mining Machinery can satisfy the scope of several meshes to several thousand meshes granularity, with a widely use such as all kinds of metal and non-metal ore mill industry, and coal and cement processing. Besides, when facing the coal processing industry, C&M Mining Machinery mill adds the special explosion-protection equipment and the high performance anti-explosion motor to make amore safety and efficiency in the coal grinding.
