Dimensional data of a typical double-toggle jaw crusher are used in the derived mathematical expressions to demonstrate their application. Moreover, starting with the equation for the angular velocity ratio of the moveable jaw, with respect to the input crank, an expression for the ideal mechanical advantage of the crusher is derived.

The primary rock breaker that is most commonly used in small plants is a jaw crusher of the Blake type, a typical section of which is shown in Fig. 4.

Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.

The most common type of jaw crusher today is the Blake crusher, patented by Eli Whitney Blake in 1858 (Weiss 1985).
