Grinding raw material and clinker causes considerable wear to the grinding mill. Starting the mill direct-on-line stresses the mill and the gearbox, increasing the risk of gearbox failure and shortens the lifetime of mechanical equipment. VSDs help optimize the mill speed to match the material flow, thus minimizing the wear of the grinding mill.
Milling Machines A milling machine is a power driven machine that cuts by means of a multitooth rotating cutter. The mill is constructed in such a manner that the fixed workpiece is fed into the rotating cutter. Varieties of cutters and holding devices allow a wide rage of cutting possibilities.
