Optimization of Cement Grinding Operation in Ball Mills

Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old.

Overview of our mills · Christian Pfeiffer

The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier. When used as a pre-grinding system in ball mill circuits, production increases of up to and more can be achieved.
