Raymond Mill Working Principle
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 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.
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.
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.
Raymond mill debugging
1, empty load test machine running at no load test machine before grinding roller device should hold the roll firmly with rope nets to avoid contact with the impact of the roller and grinding ring , and then empty the host machine running the test of not less than one hour ; Host should operate smoothly , cabinets oil should not exceed 80 ℃, temperature does not exceed 40 ℃. Analysis of the host machine and the direction of rotation shown in Figure 4 .
2 , the blower should load the boot , to be operating normally after the load , and then observe its smooth operation , no abnormal noise and vibration , bearing the maximum temperature should not exceed 70 ℃, the temperature rise should not exceed 35 ℃.
3 , the load test machine running time of less than 8 hours after the machine is working properly Raymond no abnormal noise , the pipe joints leak wind phenomenon , the test machine again after each fastener tightening , can be put into normal use.
Raymond mill winnowing process
Materials after grinding, before the sand washing plant manufacturers, the fan will be blown into the chassis, blowing powder, after the separation in the grinding chamber at the top of the analyzer, fine through the coarse material into the grinding chamber heavy grinding, fineness is specifications with the wind into the cyclone collector, after collection by the powder discharge mouth, is the finished product. Merry by returning the duct at the top of the big cyclone collector into the fan, the wind road is circular, and negative pressure in a state of flow, circulation wind by the fan air volume increase part of the road with the host in the middle of the exhaust pipe, into the small cyclone collector, purification processing.
