High-strength raymond mill is used for grinding the barite, limestone, kaolin, ceramics and slags, etc, with the hardness below scale 9.3 of Mohs and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industry, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-425 (1000 the finest) meshes. It is possible to produce 30-80 mesh coarse powder through special device in the machine.
Hongxing Raymond mill is widely used in high fine powder processing of non-flammable or non-explosive materials whose Moh’s hardness is no more than 9.3 and humidity is below 6% as barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials in more than 280 industries like mining, chemical industry and building. It can adjust its finished products’ grain size between the ranges from 80 to 325 arbitrarily; some materials’ granularity can reach 600 meshes at most.
According to the ultrafine equipment processing technology that our company grasps for years, the problems above have got a comprehensive technical renovation. When using traditional Raymond mills, we find that during processing calcite mineral, 325 mesh mineral powders contains lots of 10um ultrafine powder. If they are separated and expanded production, benefits will get increased remarkably. Therefore, we have a lot of innovation for the structure of Raymond mills.
Raymond mill is chiefly composed of mainframe, analyzer, blower, finished cyclone separator, plumbing installation and motor etc. And the mainframe consists of rack, air inlet volute, blade, roll grinding, grinding Central, Shell and motor. The auxiliary equipments involve jaw crusher, bucket elevator, electromagnetic vibrating feeder and control cabinet. Customers are able to choose flexibly according to the real situation.
The accessory equipments: jaw crusher, bucket elevator, electromagnetic vibrating feeder and control cabinet etc, it is available for the customers to make an elastic choice in accordance with the real situation.
In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force. And its rolling pressure ration is 1.2 times higher than that of the raymond grinder under the same power condition and the production output is raised to substantial degree.
When a certain degree of wear of roller and ring is affected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.
1.Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
2.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.
3.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
4.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.
5.Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach.
