3 Roller Mills is to grind non-flammable and non-explosive materials in the fields of building materials, mining, metallurgies and chemical industry with hardness less than 9.3 in Moh’s scale and humidity less than 6 percent. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite, garnet, bauxite, zircon, marble, calcite, iron ore, rock phosphate, coal, slag and so on(400 kinds of material). The granularity of the final products can be changed from 30 to 425 meshes
Application:widely used in small and medium mining, chemicals, building materials, metallurgy, refractories, pharmaceuticals, cement and other industries.
Raw Material: such as gypsum, talc, calcite, limePowder, marble, barite, dolomite, granite, kaolin, bauxite, fly ash , oxidation iron oxide red, iron Powder, etc.
Features of 3 Roller Mills：
- Higher output. Its output increases by 10%-20% comparing with 3 Roller Mills under the same power condition.
- Larger range of final fineness. Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
- Good dust control. High Pressure Suspension Mill meets the requirement of national dust-dump standard.
- Easy to operate. The whole system is combined by some independent systems, and the cohesion between the systems is good.
- Excellent sealing. The multi-class seals are adopted to keep the grinding equipment tight closed.
Applications of 3 Roller Mills：
3 Roller Mills is effective closed-circuit high fineness powder manufacturing equipment, which is applicated in small and medium mining, silicate and chemical, building-material, metallurgy, refractory material, pharmaceuticals and lime industry. It is a new style powder grinding machine, which is more advanced than ball grinder and much appreciated in many fields due to its domestic leading level in each technical specification.
