Abstract
A jaw crusher used to crush hard materials includes a frame and a fixed and movable jaw positioned in spaced opposed relationship to receive hard materials to be crushed between the jaws. A lever is pivotally connected to the frame for pivotal movement about an axis and includes first and second extensions. The first extension includes a part that is in communication with the movable jaw and a part that is in communication with the axis and the second extension includes a part in communication with a reciprocating drive and a part in communication with the pivot axis. The distance between the parts of the second extension is greater than the distance between the parts of the first extension causing leveraged force to be applied on the movable jaw on application of force on the second extension by the reciprocating drive.
