Dynamic modeling and simulation of a SAG mill
2018101 · A semiautogenous (SAG) or autogenous mills (AG) circuit commonly comprises a pebble (cone) crusher to deal with the critical size particles. The pebbles crusher is often oversized, and thus not fully utilized.
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 2555 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.
