Raymond mill





Raymond mill

  • capacity (t/h) : 0.3-9.5
  • Max feed size(mm) : 15-30
  • Cement, coal, desulphurization power plants, metallurgy, chemical industry, non-metallic minerals, building materials, ceramics, etc.
Raymond mill is commonly milling equipment mainly used in chemicals, building materials and other hundreds of kinds of materials of high fine milling processing, such as barite, calcite, potash feldspar, limestone, talc, white stone, gypsum and other inflammable and explosive materials  hardness  not greater than 9.3 moh's hardness, humidity in less than 6%. Discharge size can be adjustable from 40 to 400 meshes.

Raymond mill for different materials, different fineness, different output requirements, divided into high-pressure micro-grinding mill,high pressure suspension roller mill, etc. more than 10 models.
 
Raymond mill
Working principle
The work principle of Raymond Mill is that the rollers are rolled tightly in the grinding ring under the centrifugal force, material lifted by the shovel is ground into powder between the ring and roller, and then the fan blown up the powder through the analysis machine  to the cyclone collector, powder achieve fineness requirements through the analysis machine, can not reach the requirements return to grinding cavity and continue grinding. The exhaust air is separated by industrial filter cloth to form a powder.

Benefits

1. Higher output. Our Raymond mill’s output increases 10%-20% compared with machine under the same power.
2. Larger range of discharge size. Its between 40-400mesh (0.2mm –0.044mm). Some can reach to 1000 mesh (0.013mm).
3. Good dust control. Our machine meets the requirement of national dust-dump standard.
4. Easy to operate. The whole system is combined by some independent systems, and the cohesion between the systems is good.
5. Excellent sealing. The lapping device adopts the multi-stage seal of superimposed type, which has good sealing performance.
