Raymond Mill is mainly used for non-flammable and non-explosive materials with Mohs’ hardness less than 7 and humidity less than 6% such as barite, calcite, marble, ceramics and glass. 1.The whole plant is a vertical structure, so it occupies small area.

1.The whole plant is a vertical structure, so it occupies small area. From crushing of raw material to grinding and packing, it 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.Transmission device of main frame adopts airtight gearbox and pulley, which drives smoothly and operates reliably.
4.The techniques is so subtly that ensures the durability of whole plant.
5.The electric control system is centralized controlled, so the automaticity is high.
Firstly, raw crusher is crushed by jaw crusher to the size satisfied, and then elevated into a hopper, from where the material is transported by the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for grinding. Materials are sent to the space between roller and ring by shovel for grinding. The milled powder is sent to separator by air.
Fine powders satisfied enters cyclone collector and discharged as final products. The air goes back to blower from upper part of cyclone collector. Coarse powders will be sent back for regrinding. The system is sealed and cycled under positive and negative pressure.
