TECHNICAL NOTES 8 GRINDING R. P. King

Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill.

how to estimate the wear rate for Ball mill - Page 1 of 10

Dec 08, 2009 · Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

What is the Reason of No Fine Grinding of Ball Mill ...

The phenomenon of fine grinding in ball mill is closely related to grinding concentration, and the grinding concentration is directly related to the amount of ore. Too large or too small concentration will have a bad effect on the normal work of the ball mill. When the concentration is too large, the flow speed of pulp slows down, and the impact of grinding medium (steel ball) becomes weak.
