The AR technique graphically presented the results which indicated the best operating conditions to minimise pebble formation. The effects of mill filling on a SAG mill indicate that a higher filling produces lower pebbles.

A small bin was modeled for the cone crusher chamber when the material accumulates and perfectmixed after the crusher. The product particle size distribution of the cone crusher is shown in Fig. eccentric speed settings in Fig. 2 are 280, 360 and 440 rpm. It can be seen from the plot that the CSS and eccentric speed of a cone crusher can affect the final PSD significantly.
