Jaw Crusher - an overview ScienceDirect Topics

The capacity of a jaw crusher is given by the amount of crushed material passing the discharge opening per unit time. This is dependent on the area of the discharge opening, the properties of the rock, moisture, crusher throw, speed, nip angle, method of feeding and the amount of size reduction. In order to calculate the capacity of crushers, Taggart [8] considered the size reduction, R 80, as ...

What is a Jaw Crusher? – MEKA Crushing Equipment

A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate sector, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials. The lifecycle of double-toggle jaw crushers is longer since they do ...

01/01/2016  Since the comparative reduction capacity of the jaw crusher is given, the crusher dimensions may now be determined. For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7,
