Abstract: This paper describes the function and operation of lubrication systems for Ball Mill and SAG Mill Drives. Provided within this paper are hydraulic schematics, functional description and a general overview of system layout as well as some of the important features and factors relevant to improving the reliability of this very critical part of the grinding mill drive system.
The 42-foot ring motor is the centerpiece of the gearless drive and wrapped around the tube mill. An increase in tube diameter means that the mass of the ore being ground rises dramatically, and hence also the strain on structural elements and the motor.
SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
