The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double

In case of dynamic eccentricity, the center of rotor is not at the center of rotation, so the position of minimum air-gap rotates with the rotor. In practice, an air-gap eccentricity of up to 10% is permissible. In order to simulate eccentricity fault, a heavy weight was attached to one side of a disk coupled to the shaft.

The older long-shaft gyratory crusher which has the gear above the eccentric (Fig. 23) has another difference in that the eccentric bearing is supported by a bottom plate A. The majority of the current primary gyratory crushers are the hydraulically supported short-shaft type. Instead of being supported
