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.

Pros. Impact crushers are capable of delivering a much more homogenous, consistent and cubical end product. This makes impact crushers favourable when the final result needs to be a saleable commodity. Moreover, impact crushers can be highly efficient. They also use comparatively low energy compared with other crushers types.
