Raymond Grinding Mill Application:

 

 R-type Raymond mill is used for grinding the barite, limestone, kaolin, ceramics, and slags, etc, with the hardness below scale 9.3 of Mohs and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industry, chemical engineering and building material for high fine powder generating and processing. The particle size of finished product can be adjusted from 80 to 325 meshes at random and the particle size of part materials can reach 2000 meshes at the maximum. 

Structure of Raymond Grinding Mill:

 

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 milling plants, its passing ratio achieves 99%, this is what other mill can not 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 technics 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.

 

Raymond Grinding Mill Working Principles:

Firstly, raw material is crushed by jaw crusher to the size required, 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 are 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.
