Modification of eccentric sleeve of PXZ1422 gyratory crusher

Using modified nylon new material instead of Babbitt alloy to pour eccentric sleeve, applied in pxz1422 gyratory crusher, can be more suitable for non-impact load in crushing, reduce cost, increase service life by 4 times, and create good economic and social benefits.

Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.
