BALL MILL DRIVE MOTOR CHOICES Artec Machine The time has come to re-think our approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services.
2018/05/02· An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically 120 percent of the normal drive …
Home / SER Drive SER Drive The Slip Energy Recovery Drive (S.E.R. Drive) is a technology well proven in the industry for large power motoring systems that allows precise motor speed control at the same time that recover the slip energy in the wound rotor induction motors (WRIM).
Motor The GMD is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to
2018/04/08· A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution.
