Crusher - an overview | ScienceDirect Topics

The jaw crusher reduces the size of large rocks by dropping them into a "V"-shaped mouth at the top of the crusher chamber. This is created between one fixed rigid jaw and a pivoting swing jaw set at acute angles to each other. Compression is created by forcing the rock against the stationary plate in the crushing chamber as shown in Fig. 13.9.
