Abstract Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range (i.e ...
Abstract Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range (i.e. − 75 + 9 μm) applicable to a …
The Optimal Ball Diameter In A Mill. which can grind efficiently in a mill c is the exponent which characterizes the ball size distribution. The condition for efficient grinding defined by Eq. 7 will be fulfilled when the grain size distribution and the ball size distribution are the same which means that the parameters of both distributions are equal in Eqs. 7 and 9 m c. 10
