Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel.

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.

The calculation formula is below: B — the grinding balls diameter mm; A — the correction factor for grinding balls A 2017; for cilpence A 1815; F — the feedstock grain size in 80 of the material μm;
The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous SAG Mill via an utilized method. Miduk copper concentrator is located in Kerman Province Iran and its size reduction stage includes one gyratory crusher which feeds one SAG mill 9.75 dia.m3.88 lengthm following two parallel ball mills 5dia.m7lenghtm.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters 10 feet diameter inside liners the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos Allis-Chalmers
The majority of grinding balls are forged carbon or alloy steels. Generally they are spherical but other shapes have been used. The choice of the top or recharge ball size can be made using empirical equations developed by Bond 1958 or Azzaroni 1984 or by using special batch-grinding tests interpreted in the content of population balance models Lo and Herbst 1986. The effect of ...
