Comminution

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size by crushing grinding cutting vibrating or other process In geology it occurs naturally during faulting in the upper part of the Earth s crust In industry it is an important unit operation in mineral processing ceramics electronics and other fields accomplished with...

Cement kiln

Wet grinding of hard minerals is usually much more efficient than dry grinding When slurry is dried in the kiln it forms a granular crumble that is ideal for subsequent heating in the kiln In the dry process it is very difficult to keep the fine powder rawmix in the kiln because the fast-flowing combustion gases tend to blow it back out again...
