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.

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.

Crews have also begun modifying the mill foundations in advance of installing ball and SAG mill components, some of which have already arrived on site.

Mills Grinding. Generally ball mills are more common than Rod mills or Sag Mills, there are other types of mills available such as Vertical mills but the last three mentioned are by far the most common. Ball and mills use steel balls or ceramic balls as their grinding media. Rods mills as the name suggest use rods as their grinding media.

Functions of a Gearbox A gearbox, also known as a gear drive, has three main functions: to increase torque from the driving equipment (motor) to the driven equipment, to reduce the speed generated by the motor, and/or to change the direction of the rotating shafts.The connection of this equipment to the gearbox can be accomplished using couplings, belts, chains, or hollow …
