Double toggle jaw crushers have one jaw fixed, while the other pivots about a top hinge. This moving jaw is shaped to move firmly and squarely against the material. There is no rubbing or grinding. Only compression, which produces a generally cubical product with minimum fines. The moving jaw is very well balanced, so 95% of the drive motor power is used for crushing. While only 5% of the power is needed to move the jaw itself. As a result of this high mechanical efficiency, double toggle jaw crushers require smaller size motors.
