McLanahan | How To Size A Jaw Crusher

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".

AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training

Rose and Hill (1967) considered crusher capacity by determining the amount of time and distance a particle takes between two jaw plates. Particles in the A-B zone discharges at the next reverse movement of the jaw. The maximum size of a particle dropping out of the crusher d max is determined by the open size setting (L max).

Assessing the energy efficiency of a jaw crusher

As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber.
