Overview of raymond mill 

After many years of practice and improvement, its structure is getting perfect day by day.

For low consumption, low investment, environment friendly , small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series 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 44 micron. Through the function of separator and blower, it can meet different customers’ demand.

Working principle of raymond mill 

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.
