How does grinding roller work?

 

The special working and functional principles make every roller mill operate with a great flexibility.

The material to be ground is crushed between the rotating grinding track and the individually guided grinding rollers. Grinding is carried out primarily through the application of compressive force vertically, the secondary effect being the horizontal shear force.

 

Great Wall Steel Casting supplies grinding roller for international well-known vertical mill manufacturer. The good quality and perfect service gained trust from For Foreign Company. Therefore, Xinxiang Great Wall Steel Casting becomes its best supplier.

Grinding rollers of Great Wall Steel Casting were applied to the cement vertical mill with annual output 900,000 tons of Henan Yuhui Huanghe Building Material Co., Ltd.
