Raymond mill widely used in grinding equipment of mine, cement, chemical industry, is one of the important equipment of non metallic mineral deep procession. Since its strong stability, adaptability and high cost performance it has popularized in non metallic mineral processing field. Applied in grinding various non plastic ore, mineral soil, metallic oxide, chemical composition etc. which Mohs hardness not more than grade 7, humidity less than 6% non flammable and combustible material such as speckstone, dinas rock, graphite, fluorite, magnesia stone, bentonite, kaoline, pottery clay etc.
 
Technical parameters: 
 
Performance characteristics:
 
1. Vertical structure, small floor space, strong systemic, is an independent production system from raw material rough producing to conveying, powder processing and final packing.
 
2. Through screening rate reach 99% compare to other grinding equipment.
 
3. Raymond main engine gearing use airtight gear case and pulley, stable conveying, reliable operation. 
4. Raymond mill main parts all made of excellent casting and section bar,   refined craft, careful process, ensured durability of the complete set of equipment.
 
5. The electric system apply centralized control, the grinding plantbasically achieved unattended operation.
 
Raymond mill operating principle:
 
When it operating, feed the material need grinding to the mill, use the grinding device, revolute round the vertical axis, meanwhile self rotate. Since the revolving centrifugal force, the grinding roller swing outwards, adpress to the grinding ring, the schleifer scoop up the material convey to the place between the grinding roller and grinding ring, the roller rolling and grinding the material.
