Raymond Mill also known as mill, mountain stone. Mine is a new milling equipment, milling machine is suitable for the mining, building materials, chemical industry, metallurgy industry, can be of limestone, calcite, barite, dolomite, feldspar, marble, talc, gypsum, kaolin, bentonite, phosphate rock, manganese ore, iron ore, glass, ceramics, activated carbon, carbon black, refractories, insulation materials, chemical raw materials such as Mohs hardness less than 7, and humidity below 6% of 300 kinds of non-flammable material for mill processing, product fineness can be adjusted between 30-325 mesh (the smallest 600 mesh). 
 Raymond Mill works: 
 Materials to be processed into the host Raymond mill grinding chamber, due to centrifugal force when rotating the spindle, roller out swinging, pressed on the grinding ring, blade to scoop up material sent between roller and grinding ring, rolling with the roller to achieve the grinding, crushing purposes. Material after grinding, the powder with the blower circulating air through the analysis of machine sorting, fine through coarse material falls back to the grinding chamber for regrinding, qualified with the powder into the air cyclone powder collector through the powder discharge pipe is finished. Cyclone powder collector through the air into the blower after the formation of closed loop, so that the machine will continue to work properly. I wind through the duct into the dust remaining after purification from the plane. 
 Raymond mill main structure: 
 Mainly by the host machine architecture, parser, fans, finished cyclone, cyclone powder and air tubes. Among them, the host from the rack, inlet volute, blade, roller, grinding ring, casing composition 
 Raymond mill structure: 
 1, three-dimensional structure, small footprint, complete and strong, refined powder from the block expect independent self-contained production system. 2, the refined powder fineness uniform rate of 99% through the sieve, which is difficult to have other milling equipment. 3, machine drives using sealed gear box and pulley, drives smooth, reliable operation. 4, the important parts are of high quality steel, wear-resistant parts are high-performance wear-resistant materials, machine wear, reliable operation. 5, the electrical system of centralized control, easy to use. 

 Raymond Mill Production Notes: 
 1, for the Raymond mill flour machine properly, the device should be developed, "the safe operation of equipment maintenance system" can ensure the long-term safe operation of the Raymond mill, and have the necessary maintenance tools and grease and corresponding accessories. 
 2, Raymond roller mill plant using more than 500 hours or so to replace the roller, the roller bearing kit must be cleaned of all, the damaged parts should be replaced, fuel pump and the tool can be used to manually add grease gun . 
 3, Raymond mill in the use of the process, there should be a fixed charge of personnel, the operator must have a certain level of technology. Raymond mill before the installation the operator must carry out the necessary technical training, so that understanding the principles of Raymond mill performance, familiar with operating procedures. 
 4, Raymond mill use for some time, maintenance should be carried out while on the roller blade grinding ring repair replacement of wearing parts such as handle, roller device in use before and after the bolt nut should be carefully examined to see if is loose, whether to add a little grease.
