Operation Guide for Vertical Roller Mill in Cement Plant ...

The depth of these scratches will depend on the size of grit of the wheel and the amount of vertical pressure applied during grinding. (A finer grit results in smaller and shallower scratches.) Because the strength of the silicon is inversely proportional to the depth of the scratches, it is important to minimize the roughness of the wafer surface.

POLYCOM high-pressure grinding roll

Finish-grinding The use of the high-pressure grinding roll for finish-grinding permits maximum energy sav-ings. In comparison with conventional ball mill grinding systems, up to 50 % of energy can be saved. Feed material with up to 6 % moisture content is dried in the separator. Material with higher moisture contents is dried in a separate

YGM High Pressure Grinding Mill-Vanguard Machinery

Inside the host of the high-pressure grinder, a 1000-1500 kg high pressure spring is fastened on the roller hanger. After starting work, the grinding roller revolves around the spindle, and under the action of high-pressure spring and centrifugal force, rollers close to the grinding ring.
