Abstract The theory of the calculation of the size distribution of the equilibrium mixture of balls in a ball mill is developed. The differential equation is solved for wear laws of the form wear rate per ball ∝ r2 + Δ where r is ball radius. Δ = 0 gives the Bond wear law and Δ = 1 gives the Davis wear law. Methods of determining Δ are illustrated. Experimental data are presented which

Ball size distribution in tumbling mills is commonly used to optimally control the mill product size distribution leaving the mill. This is owing to the fact that each ball size effectively break a particular size range in the mill.

In this research, ball size distribution which is a function of make-up ball sizes was investigated to optimise the milling stage of a grinding circuit in order to maximise the production of the narrowly-sized mill product for floatation, in this case − 75 + 9 μ m. 2. Review of grinding and ball wear models.

Difference Between a Rod Mill and Ball Mill. Rod Mills has a very define and narrow discharge product size range. Feeding a Rod Mill finer rocks will greatly impact its tonnage while not significantly affect its discharge product sizes. The 3.5” diameter rod of a mill, can only grind so fine.

Ball mill classifier systems have been improved over time and are now capable of achieving much finer products. In the past, a particle size with a D97 of 10 microns was only possible. Now particle sizes down to a D97 of less than 3.5 microns can be achieved, with a D50 in the range of 1.5 microns.

The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.
