Raymond mill is suitable for grinding the nonflammable and non-explosive materials with humidity below 6% and Mohs hardness less than 7 such as barite calcite feldspar limestone marble glass and so on. It is widely used in mining chemical industry and building materials.
Firstly, raw material is crushed by jaw crusher to the size required, then 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 the ring and rollers to accomplish the grinding. After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.
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. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates 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.
