grinding performance in vertical roller mill

Copper ore grinding in a mobile vertical roller mill pilot

10/03/2015· Within the scope of the study ore grinding performance of the vertical roller mill was investigated with mobile pilot plant. In this context, chalcopyrite ore of a plant having rod and ball milling circuit was ground under different operating modes e.g., air swept and overflow, and process conditions, then samples were collected around the system. The collected samples were characterized in terms of size distributions which were then used in comparing the performances

Vertical Roller Mill Structure And Working Principle

The materials are pulverized by the roller when by pass of the groove on the grinding table. The crushed materials are brought up by vane high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator on the top of the mill,the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder
