Roller mill raymond introduction:
ShanghaiZenith has 20-year experience of Raymond roller mill manufacturing and development. Recent year we keep improving Raymond mill technology on performance and quality. Final size could be adjusted between 100-325 mesh. Raymond mill can process barite, calcite, potash feldspar, talc, marble, limestone, ceramics, glass and other non flammable materials whose Moh's hardness is less than 7, moisture is less than 6%, Raymond roller mill is used in mining industry, chemical engineering, construction material and metallurgy industry over 280 kinds material process.
Range of Application
Mining industry, chemical engineering, construction material and metallurgy industry over 280 kinds material process. Such as Limestone, calcite, fly ash, calcium carbide, kaolin, calcium carbonate, coal gangue, gypsum, grain slag, ore slag, coal dust, bentonite, barite, marble, talc, refractory material, etc.
Raymond roller mill Working Principle
Raymond roller mill whole structure is constituted by main machine, analytical engine, plumbing installation and air blower, crusher, elevator, electromagnetism vibrating feeder and electric motor. After being crushed to requested size, material will be taken to storage hopper by elevator, then vibrating feeder will convey material evenly and continuously to main machine grinding chamber, under the force of centrifugal, grinding roller swing outward and press on grinding ring, shovel blade scoops material up to gap between roll and ring, grinding roller rolls to grind material. After being grinded, fine powder will be taken to classifier to be classified, coarse material will fall down to be reground, standard fine powder will go to finished product cyclone collector and discharged by discharge powder tube. There is moisture in material, the heat caused by grinding process makes moisture evaporated, all the connectors of pipe are not close-connected, outside air will be inhaled, cyclic pressure will be increased, grinding mill could work under condition of negative pressure state, incremental air will be discharged to dust collector through ductwork, and it will be discharge into atmosphere after purification.
Raymond roller mill advantages:
1. Independent Production System
Independent production system can process material from bulk material to powder
2. High Quality Wear-resisting Material
Major parts of Raymond mill adopts quality steel, wear-resistant parts adopts high quality wear-resisting material, good wear-resisting property of complete machine, stable operation.
3. Uniform Fineness, Sieving Rate 99%
Even final product size, sieving rate could reach 99%, incomparable performance
4. Main Machine Transmission
Sealed gear case and belt wheel, smooth transmission, reliable performance
