Raymond mill (Raymond roller mill) is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, and glass. The fineness of the finished products can be adjusted from 100 meshes to 325 meshes according to requirements. It is the mainly and widely used grinding machine.

After many years of practice and improvement, its structure is getting perfect day by day. Due to its low consumption, low investment, environment friendliness, little floor space and much more efficiency than the traditional mill, it is widely used in the fields of metallurgy, building materials, chemical industry and mining for powder processing.
1. The whole plant is a vertical structure of systematic characteristic, so it occupies small area. It is an independent production system from raw materials crushing to grinding and packing.
2. Compared with other milling plants, its passing ratio achieves 99%, which is beyond other mills' reach.
3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4. Main parts of the whole plant are made from cast and steel of high quality. The techniques are so subtly that they ensure the durability of the whole plant.
5.The electric control system is centralizedly controlled, so the automaticity is high with no people needed in the operating room.
1. To operate the equipment, you have to be technically trained to know the principle and rules of operation. Someone should be specially selected and put in charge of the operation.
2. To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed. Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.
3. After a period of usage, the equipment should be checked, worn-and-torn parts such as rollers, rings and shovels be replaced. Be sure to fasten connecting-bolts and nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.
4. Roller should be replaced after 500-hour use. Check and wash bearings in it and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).
