Advanced comminution modelling: Part 1 – Crushers☆
DEM models including breakage are capable of simulating industrial scale crushers. • Compression and impact crushers can be investigated in detail using these models. • Breakage and flow are analysed in twin roll and cone crushers. • Crushing behaviour in a VSI involves multiple mechanisms of impact breakage.

Jaw Crusher
The jaw crusher is primarily a compression crusher, while the others operate primarily by the application of impact. 4.2. Design of Jaw Crushers. Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel.

Impact crushers must always be fed on all width of the machine (80 to 90%) to ensure an even wear of the hammers. Concentrated feed will generate localised wear at hammer centre, when material stream is not correctly spread across by the crusher feed chute. Typical case of wrong feed method is a direct material flow penetrating
