A contribution to ‘ball wear and ball size distributions ...

Abstract Recent work by Austin and Klimpel concerning the nature of ball wear in rotary mills is discussed. The remarkable ambiguity that the results of a marked ball test can be accurately described by either the volume or the surface theories of ball wear is explained, and it is concluded that such tests cannot be used for determination of the values of the Austin—Klimpel parameter Δ ...

Evaluation of grinding medium wear in stirred ball

The standard fine grinding machines in the minerals industry are stirred mills whose performance largely depends on the competency of the grinding medium. Medium wear in stirred mills is one of the key parameters for medium selection. A wear evaluation methodology is developed and applied in this paper to measure the wear rate of river sand using a laboratory batch stirred mill.

Optimization of mill performance by using

2015-4-16  As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

Effect of the operating parameter and grinding media

2019-12-15  The experimental results showed that the Abbott-Firestone curve can evaluate the lifter surface topography. The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate.
