The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S dBWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P information, along with the ore specific gravity, is used to calculate necessary mill sizes and motor power in industrial applications.
includes a Bond Ball Mill Work Index test on SAG ground ore from the first stage of the test. The ratio of SAG pinion energy to Bond BM Wi is a key parameter in a SAG mill grinding circuit design, because this ratio controls the power split between SAG and ball mills at the target T80 transfer size( ).

Calculate the power draw of the ball mill (at the pinion), Pbm: Pbm = Tb x kwb(kw) 1. These calculations are for overflow ball mills. However, full grate discharge mills* draw approximately 15% more power on average than overflow mills with the same internal length. For dry grinding, grate overflow ball mills, the power draw isapproximately 8 % ...
The drive of the ball mill consists of an induction electric motor, twostage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell, see Figure 1, taken from [1]. Figure 1.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
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. Gear mesh frequency is present at 1x to 3x and similar amplitudes on both sides.
Due to the criticality of the pinions on a ball mill, most companies will have a spare available. And this is where the expertise of CBC Australia is so important to hard rock mining operators around Australia. The CBC engineering team habitually custombuild pinion assemblies for customers in this segment.
Grinding and processing. WEG offers the most reliable and efficient solutions for milling plants for ferrous and nonferrous products with their experience of mill drive systems. In the heart of a processing plant, the ball and SAG mills must be driven by solutions that adapt to the characteristics of the minerals in line with the whole process.

Identifying a Failing Ball Mill Pinion Bearing Unusual Noises. One of the primary indicators of a failing pinion bearing is the emergence of unusual noises during the operation of the ball mill. Listen for grinding, knocking, or rumbling sounds, as these may suggest that the bearing is experiencing excessive friction or misalignment.

The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
