Stone Crusher. Jaw Crusher The larger eccentricity of pitman shaft provides a motion that pulls the material to the bottom of the jaw plate. Spherical, self-aligning roller bearings, straight-bore pitman bearings and tapered-bore body bearings provide maximum strength to the pitman shaft and bearings for a long extended maintenance life. More. Jaw crusher eccentric shaft

 · Productivity of the crusher can be improved upon by increasing the eccentricity of the eccentric shaft, use of reversible jaws, bush bearing and easily adjustable toggle plate. Vibrations and fatigue cracks in the crusher frame will be nipped in the bud through structural analysis at design stage. Determination of the optimal angle of

The crushing process takes place between a ixed and a moving jaw. The moving jaw dies CONE AND GYRATORY are mounted on a pitman that has a recipro- CRUSHERS cating motion. The jaw dies must be replaced regularly due to wear. Both cone and gyratory crushers have an oscil-

exact breaking load can be calculated. When the bolts are over­ stressed and break, the toggle remains in the crusher and simply hinges about the central shaft. This action puts the crusher in neutral and crushing ceases. New bolts are inserted and the crusher is back in operation with minimal downtime. Problems Associated with Jaw Crushers

A variable throw eccentric cone crusher. The cone crusher comprises a frame, a crusher head supported on the frame for gyration about a first axis, a bowl supported on the frame in spaced relation to the crusher head, and a mechanism on the frame for varying the eccentricity of the gyration of the crusher head. An eccentric member engages the crusher head and is
