Center drive and side drive are two common drive modes for a ball mill. Center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the large girth gear which is bolted on the flange of the mill body.. Materials are fed into the mill at a fixed flow rate along the shaft-less ...
However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system.
