Raymond mill

 

Shanghai Shenbang is a professional manufacturer of the Raymond mill ,which are mainly used in processing over 280 kinds of mining and chemical powder manufacturing with the Mohs hardness of less than 7 degree such as marble, liZenithne, calcite ,etc. And it has realized the any adjustment at the fineness range of lower 400monyh.And the Raymond mill are mainly including the grinding ,analysising, dust-catcher system. And the it can realize the once-time shaping from the particle size to the powder manufacturing with the advantages of evenly fineness , high screening efficiency ,long service life of the anti-abrasion parts , convenient maintenance ,low dust powder ,small covering area ,high whole style ,low investment cost and high returning rate .
This kind of Raymond mill adopts the advanced structure and are developed on the basis of large-size Raymond mill with the advantages of high-efficiency ,low energy-consumption, small cover area, and low investment cost . And the grinding roller will closely pressure on the grinding ring by the effect of the eccentric force .So when the grinding roller and ring have reached some wearing thick degree , it still can not influence the production and fineness of the final products .And the changing period of the grinding roller and ring is very long ,so that it has eliminated the defects that the short changing period of the eccentric crusher .

Application of the Raymond mill

And now the Raymond mill has found extensive application in the field of Metallurgy, building materials, chemical, mining .Besides ,it is suitable for processing the powder under the condition of Mohs hardness lower 7degree and the moisture lower 6% and other nonflameable explosive mining materials ,such as Gypsum, talc, calcite, liZenithne, marble, feldspar, barite, dolomite, granite, kaolin, PENG soil, medical stone, bauxite, iron oxide red, iron ore ,etc.And the final products fineness can reach the range of 613μm-440μm.We can satisfy various requirements by the common effects of analysiser and the wind machine .

Working principle of the Raymond mill

The Raymond mill can crush the large-size materials to the required feeding size and then will deliver the materials to the storehouse by the dustpan lift ,which will be evenly delivered them to the crushing cavity of the main machine body by the electromagnetism vibrating feeder. And the materials which have entered the grinding cavity will receive the grinding between the grinding roller and ring ,thus producing the powder ,which will be brought to the analyzer to grade by the wind machine.And the required fine powder will enter thr large cyclone collector by the air stream to receive the seperation and collection .And at last ,the final products will be discharged out by the tripper .And during the working process,the shovel system have played a key important role ,which is positioned on the lower end of the grinding roller .And the shovel and roller will shovel up the materials to the space between the grinding rollers and form the pad layer which will receive the extruding force produced by the rotating of the rollers .And then the materials will be crushed ,thus achieving the aim of the powder making.
