stone crusher/ grinding mill/ vertical pulverizer

Being a vertical rolling mill, the column mill adopts a grinding principle of continuous and repeated rolling of material bed under medium speed and medium pressure, which is characterized by simple and reliable structure and extremely low failure rate. The motion of the upper structure of the machine transmits to the main shaft, making the latter resolving, which makes the rollers connected to the shaft resolve in the inner conic lining(the gap between the rollers and the lining plate is adjustable but without contact). The material is fed from the machine upper structure and forms a material bed between the rollers and the lining by its own weight and the upper material pushing function, and is pulverized by repeated rolling of the rollers, and finally is automatically discharged from the lower part of the mill. Because the rollers only make regular revolution and rotation, the force exerting on the material bed mainly comes from the pressure produced from flexible devices, thus the ernergy consumption and abrasion caused by the shocking between the rollers and lining plate are avoided. Therefore, compared to other grinding equipment, its energy-conserving and abrasion-reducing effects are very remarkable. In addition to its applications in fine grinding, currently it is also the best equipment for coarse grinding and ultra-fine grinding.

1) Compared with other pulverizer under the same power conditions, the output of this machine is increased by 20-30%.



2) All the mineral materials with Mohs hardness below 9.3 can be crushed.



3) The finished powder has a wide range of particle size from the maximum particle diameter of 0.613mm (30 mesh) to the finest diameter of 0.013mm (1000 mesh), while the normal particle diameter is around 0.033mm (425 mesh).



4) Its dust-removing effect exactly meets the National Dust Discharge Standard.



5) The classfier is easy for adjustment.



6) The grinding unit adopts a superposition multi-grade sealing with good sealing performance.

High pressure suspension grinder mill is used to grind barite, limestione, ceramics, etc, such non-inflammable and non-explosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjusttable in the range of 60-1250 mesh(It can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.
