The Raymond mill is used for grinding more than 280 kinds of materials whose Mohs hardness is less than 9.3 such as the barite, limestone, kaolin and slags, etc in the mining, metallurgical industry, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-325 mesh.
- 1. Driving system of main frame adopts airtight gearing and pulley to guarantee the smooth drive and reliable operation.
- 2. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. The crushing of raw material, grinding and packing is an independent production system.
- 3. The electric control system is controlled centralizedly, so the automaticity is high, the people is not needed in the operating room.
- 4. Main parts of the whole plant are made of cast and steel of high quality. The subtle technics ensures the durability of whole plant.
- 5. Compared with other milling plants, its passing ratio achieves 99%, which is what other mill can not reach.
When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hanging on the star rack. With the centrifugal force generated by rotation, milling roller wings press on milling rings to grind materials between milling roller and ring so that the materials are crushed by the milling machine.
