There are generally 12 models for coarse crushing in the PE series. The parameter information of each model is different, and the particle size of the crushed stones is also different. Among them, the recommended model that can crush 40-80mm stones is PE-400×600 and PE-500×750. ... CFTC online service will …

A model has been developed to describe the breakage behavior of particle breakage in a smooth double roll crusher. In addition to this, an empirical relationship has been obtained between Hardgrove Grindability Index (HGI) of material and breakage parameters. The model uses matrix method of breakage process analysis.
