Top Quality Powder Raymond Grinding Machine

1. Introduction of Raymond Grinding Machine

1. Raymond Grinding Machine for low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill, the Raymond Grinding Machine is widely used in the field of metallurgy, building material, chemical industry and mining to process powder.

2. Raymond grinding machine is used in grinding the non-flammable and non-explosive stuff which has the Moh's hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44micron.

3. Through the function of separator and blower, raymond grinding machine can meet different customers' demond.

2. Structure of Raymond Grinding Machine

1.The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system;

2. Compared with other grinding plants, its passing ratio achieves 99%, this is what other mill can not reach;

3. Driving systemof 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 is so subtly that insures the durability of whole plant;

5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

4. Working Principle ofRaymond Grinding Machine

Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.

After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.

5.Maintenance and Repair of Raymond Grinding Machine

1. Prior to installation of the equipment, all the people who will be assigned to operate the equipment 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, to replace worn-and-torn parts such as rollers, rings and shovels. Be sure to fasten connecting-bolts, nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.

4. Roller should be replaced after 500-hours use. To check and wash bearings in it and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).
