McLanahan | Sampling Jaw Crushers
Motor power is applied to the crusher drive shaft, which in turn transfers rotation to the eccentric shaft. Rotation of the shaft causes two types of motion in the moving jaw. The first is a cyclic, pivoting open-and-close motion caused by the top of the moving jaw leveraging against a toggle plate at the bottom of the moving jaw.

The pitman is generally given a nearly vertical motion by the eccentric shaft, and since one of the toggles is mounted in rigid state at one end of the crusher frame (Fig. 4.2 A), the reciprocating motion of the pitman causes the other toggle to move the jaw back and forth. Crushing is accomplished only when the swinging jaw moves towards the ...
