Principle overview：
The grinding roller is tightly rolled on the grinding ring under the centrifugal force, material be shoved up to the between of grinding roller and grinding ring , the material crushed into powder in the grinding pressure , and then the powder material is blown to the classifier under the action of the fan, the material reached fineness requirement through the classifier, the material can not reach the requirements need to return to the cavity to continue grinding, the material passed the classifier into cyclone separator to separate and collect them.
Selection instructions：
1. The three-dimensional structure of Raymond mill has small footprint, complete set performance is strong, from the block to the finished powder independently into a production system.
2. The fineness of the finished powder is even, and the screening rate is 99%, Other milling equipment is difficult to have.
3. Main motor driving device of milling machine adopts closed gear box and belt wheel, smooth transmission , reliable operation
4. The important parts of Raymond mill takes high quality steel,wear parts takes high performance wear-resistant materials,which have high wear resistance and reliable operation;
5. The electrical system takes centralized control, milling workshop can realize unmanned operation, and the maintenance is convenient.
Model Description：
Mainly used for barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, Mohs hardness no more than 9.3, non inflammable and explosive mineral, chemical, building and other industries with humidity below 6%, more than 280 kinds of superfine powder can be processed.
