08-12-2009· 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.
It is concluded that untrained personnel can use a simple small-scale procedure to evaluate relative but not absolute grinding media wear rates. rate of mill wear to obtain close estimate
For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.
Media wear rates are not repeatable neither only by self-grinding in water nor only by grinding with mineral slurry. • New proposed wear-test method combines advantages of the above two commonly used methods. • Repeatable results on wear rates can be obtained by the combined grinding method.

A common used equation to compute the wear rate is (Archard,1953). V i =k i F s. where F is the normal load, s the sliding distance, V i the wear volume and k i the specific wear rate coefficient. Index i identifies the surface considered. The k-value is given in m 3 /Nm or m 2 /N, sometimes in mm 3 /Nm.

28-11-2020· The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications. In this paper the BMA test methodology was applied to investigate the wear rates
The concern regarding grinding media consumption rates is as old by Moly-Cop Peru to further improve the capability of the empirical model originally developed by Benavente to estimate grinding media wear rates. The results of the research enabled us to build a more robust and confident model for estimating the grinding media wear rate.

The cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. In spite of this importance, however, the amount of information in available on this subject is amazingly small and, unfortunately, is insufficient to form the basis of

media at Mount Isa. The materials to be tested were obtained in the form of large diameter balls and were run, along with the regular ball charge, in a large ball mill operating-under normal grinding conditions. At selected. intervals, the test balls were removed from the mill, weighed and identified, and their relative wear rates determined.
