Design 6.1. Operating and principle in detail The mechanism of jaw crusher is to crush using impact on the upper parts of the jaw, with a little shear towards the bottom. Jaw crushers consist of two jaws. One fixed and the other reciprocating. The opening between them is largest at the top (gape) and decreases towards the bottom (set).Web

The mechanism and motion characteristics of these crushers also differ. The single toggle jaw crusher produces a downward and forward motion, which results in higher throughput. On the other hand, the double toggle jaw crusher creates a nutcracker-like action with its unique circular motion, providing more control over the final product size.Web
