Raymond mill introduction
Raymond mill adopts advanced structure of similar products at home and abroad, and to update the industry on the basis of the improved design from Raymond mill, the device is higher than the mill efficiency, low power consumption, small footprint, a small one-time investment. Roller centrifugal force of tightly compacted in the grinding ring, so that when roller, grinding ring wear to a certain thickness does not affect the yield and fineness of the finished product. Roller, grinding ring replacement cycle is long, thus excluding the replacement of wearing parts centrifugal mill short cycle ills. Winnowing the aircraft is in the fan airflow - mill shell - cyclone - the fan circulating the job, so less than the high-speed centrifugal mill dust, clean workshop operations, environmental pollution.
Raymond Mill Working Principle
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.
Raymond mill working principle has some unique features in structure
1. The three-dimensional structure covers small floor area.
2. The fineness of the finished products is uniform; the rate of the permeability through the scree can be up to 99%.
3. The driving device of the Raymond mill is equipped with the sealed gear case and pulley; smooth transmission and reliable operation.
4. The important parts are made of high-quality steel, wear-resistant parts are made of high-performance wear-resistant materials, the wear resistance of the whole machine is high. With these features, Raymond mill can play its advantages to the utmost.
Application of raymond mill
Raymond Mill is suitable for making powder equipment at high closed circuit circle from all kinds of mine, chemical industry, building material, metallurgy. It can mill quartz, feldspar, calcite, talc, barite, fluorite, rare-earth, marble, ceramic, bauxite, manganese ore, iron mine, copper, phosphate ore, etc, whose Moh”s hardness less than 7 degree and the moisture is lower than 6%. The final size can be controlled from 0.044mm to 0.125mm, which equal with that from 100 mesh to 325 mesh though Pendulum crusher.
Factors affecting the production capacity of raymond mill
1, the hardness of the material. Harder materials Raymond mill up more difficult and more serious wear and tear on equipment . Raymond mill is slow , of course, Raymond mill capacity is small .
2, the humidity of materials, ie materials containing moisture in large , easy to adhere to the material content of Raymond mill , it is easy to plug the next conveying process , resulting in Raymond mill capacity is reduced.
3 , Raymond mill fineness of the material , fineness requirements, which called Raymond mill out the finer material , the smaller the Raymond mill capacity.
4 , material composition, Raymond mill before more fine material in the more influence with Raymond mill , because these adhesion of powder is easy to transport . For more fines content should advance once sieve.
5 , the viscosity of the material . That the viscosity of the material , the more likely adhesion .
6 , Raymond mill parts ( hammer , jaw plate ) better wear resistance Raymond mill Raymond mill capacity greater , if not wear, will affect the Raymond mill capacity.
