Raymond Mill

Brief introduction:
(Raymond machine) is a new kind of milling equipment of highly efficient closed loop instead of ball mill,which is applied to small and medium size mining, chemicals, building materials, metallurgy, refractories, pharmaceuticals, cement and other industries. It is of high efficiency, low power consumption, small footprint, less investment . Roller tightly compacted in the grinding ring under the effect of centrifugal force , so when roller and grinding ring wear to a certain thickness ,high-pressure adjustment spring length, to keep roller mill Central a constant pressure. Thus ensuring a stable yield and fineness. Grinding roll and grinding ring from Tengfei machinery, have a long update cycle,thus avoid to update wear parts at a short time as centrifugal mill .

Structural components:
Raymond mill mainly by the host machine, analysis machine, blower, finished cyclone classifier,plumbing , motors and other components.composition parts of host are rack, inlet volute, blade, roller, grinding ring, cover and motor. Auxiliary parts are jaw crusher, bucket elevator, electromagnetic vibrating feeder, cabinet, users can flexibly select them according to the site.

Technical Advantage:
1. It has low production cost, and high performance.
2. Solid structure, small coverage area, strong set, to make a production system from the block material to the finished products.
3. The fineness of the finished powder is uniform, passing sieve rate is 99%,and other grinding equipment is hardly available.
4. The machine has good stability and high reliability. 
5. Important parts are made of high quality steel, and wear-resistant parts are made of high-performance wear-resistant materials, the wear resistance is high and it operate reliably.
6. The product has good size composition.
7. Electrical system adopts the centralized control, grinding workshop basic unmanned operation can be realized.

For milling of non-flammable material such as barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorspar, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, manganese, titanium, copper, chrome ore, refractory materials, insulation materials, coal char,coal powder, carbon black,argil, bone powder, titanium dioxide, iron oxide, quartz.Which Mohs hardness is below 7 degree and humidity is below 6% .Raymond mill is widely applied to chemical, construction and other industries, on milling of more than 300 kinds of materials for high fine powder processing, product size is adjustable in the range of 80-325 mesh , part of the finished product size is up to 600 mesh.
