2013-4-1 · Multi-Component AG/SAG mill model structure. According to the preliminary modelling findings, the breakage rates for each component vary according to their proportion in the mill fresh feed. The reason behind this variation is that different feed blends result in different compositions in the mill charge, which act as grinding media.

Dynamic Modeling and Simulation of SAG Mill Circuits

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.
