Tumbling mills are most commonly rotated by a pinion meshing with a girth ring bolted to one end of the machine (Figure ). The pinion shaft is either coupled directly or via a clutch to the output shaft of a slowspeed synchronous motor, or to the output shaft of a motordriven helical or double helical gear reducer. In some mills ...

The capacity of ball mills depends largely on the reduction ratio as well as on the hardness of the material. Output of the mills cannot be calculated theoretically. The output figures for closedcircuit grinding mills operating with bucket elevators and centrifugal separators are approximately the same as those for airswept mills.

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*.

The torque on the pinion is simply the tangential force (force on the rack) multiplied by the pinion radius. Tp = torque on pinion (Nm, ftlb) rp = pinion radius (m, ft) Remember to divide the pinion diameter by 2 to get the radius, and by 1000 to convert from mm to m (or by 12 to convert from inches to feet). dp = pinion diameter (mm, in)

Usually, the pinion fails prior to the gear, by adding a positive profile shift, the bottom the pinion becomes wider (while the tip becomes narrower) thus making it stronger.
