• Raymond Mill

    Raymond Mill is most widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, plaster, glass, etc. Moh's hardness of which is not greater than 9.3 , and humidity below 10% of non-inflammable and non-explosive mineral, chemical, construction and other industries,including more than 280 kinds of materials high, fine milling process. The particle size of products is from 80 to 325 meshes and the fineness of part of the materials can reach 600 meshes.

Working Principle Of Raymond Mill:

After material is fed into the main Raymond Mill grinding room, with the effort of spindle rotation centrifugal force, the grinding roller swings outside and presses on the grinding ring; blade scoops up material between grinding roller and grinding ring to grind and crush with the rotation of grinding roller. After material is grinded, the powder is sorted with the blower circulating air through the analysis of machine, coarse fineness material falls back to the grinding chamber to be re-grinded, and qualified powder feed into the cyclone powder collector and sent out through a powder discharge pipe. Through the cyclone powder collector and then into +the blower, airflow forms closed –circuit to make the machine work continuously; remaining wind through the duct into the duster is purified and sent out.

Characteristics Of Raymond Mill:

1.Host machine take up less land, step finished from raw material to final products.
2.The fineness of final products is well distributed, 90% of through screen ratio.
3.The device of motor conveyor adopts sealed gearwheel case and belt wheel, transmits stably and operates reliably.
4.Adopt imported best steel with key components, high performance wear-resistant material with wear parts,the whole m achine with high wear-resistant.
5.The electrical system introduces foreign central controlling technology, so that it can work without people in the workshop and the maintenance is easy and convenient.
