Introduction

    Raymond mill is used for grinding the barite, limestone, kaolin, cement, slag, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and nonexclusive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-325 (600 the largest) meshes. It is possible to produce 30-80 mesh coarse powder through special device in the machine.

Operation Principle

    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 airflow system is closely sealed up and circulated under condition of negative and positive pressure.
