The trend to larger grinding mills with the attendant increase in motor drive horsepower has affected the options for drive equipment. Also the development of large adjustable speed drives has created new possibilities for mill drives. Grinding mill torque characteristics, drive requirements, and torsional excitations of the various types of available drives will be briefly reviewed.
Jan 01, 2018· The collisions between particles (both balls and grinding material) and the mill shell generate forces which are directly related, not only with vibration, but also with the mill load torque. As a consequence, it is reasonable to assume that the dampening effect accompanying the variation on the mill filling level give rise to a modification in ...
