Oct 19, 2006· What it is the optimun speed for a ball mill ? posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts.
2 GEARLESS MILL DES The gearless mill drive eliminates ringgear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record
field in the air gap of the motor, eliminating the gear reducer, the ringgear and the mechanical related issues faced by maintenance with ringgeared mills. In fact the rotor of the ring motor is the mill itself and the stator is built around the mill shell. This is also the reason why the ring motor is also known as wraparound motor. 9 12 6 ...
Shell supported ball mills are ideal for the use of ring motor drives: 3 Because of the high rigidity of the mill shell, troublefree transmission of the magnetic forces is assured. 3 Due to the individual selfadjustment of the sliding shoes, the pole pads attached to the mill shell can be centered in the stator of the ring motor.
