roller mill motor drive schemes

 · The main advantage of an electrical drive is that the motion control can be easily optimized. Put simply, the system which controls the motion of electrical machines are known as electrical drives.A typical drive system is assembled with an electric motor (there may be several) and a sophisticated control system that controls the rotation of the motor shaft.

 · A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
