A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.

2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, 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

Ball Mill SPEED REDUCER DRIVE. This is essentially a direct connected drive permitting the use of higher speed motors. The motor shaft is connected to the high speed shaft of a reducer by a flexible coupling and similarly the low speed shaft and pinion shaft are coupled.

The mill is estimated to be capable of drawing the 5500 kW at the pinion at 75% of critical speed with a 12 to 15% or greater ball charge and a total charge of 28%. The mill should be able to operate at the design conditions (10% ball charge, 28% total charge) in the speed range of 50% to 75% of critical speed over the full wear life of the liners.

These large coal crushing drive systems are usually rotated by motor-driven gearing. A typical application consists of a motor-driven primary single-stage reducer that, through a flexible coupling, drives a large open pinion which in turn, meshes with a large ball mill ring (girth) gear that is attached directly to the ball mill.

MINE. Ball mill special PM motor： In the traditional ball mill, the two most common transmission modes are : The 1st type: open peripheral gear transmission: that is, winding asynchronous motor drive reducer -> reducer (or large winding synchronous motor) drive pinion-> pinion meshing with gear ring mounted on the mill roller drive the mill.
