ABSTRACT:
The disclosure relates to an improved rotating impeller table for a secondary impact crusher comprising a side discharge port containing housing incorporating dove tailed abrasion resistant wear elements disposed on the external cylindrical wall thereof. The dovetailed wear elements overlap and are supported by removable lower edge wear liners which also protect the outer edge area of the lower part of the housing. A removable top liner retains the dove tailed elements in position and protects the upper part of the housing from abrasion. A removable and repositionable wear ring fits within an annular opening in the top of the housing and may be repositioned at least three times to essentially triple its wear life. Upper and lower centrufugally locking flat and ramped liners are disposed within the housing on its upper and lower ends. Parallel planar vertical walls, deflection plates and pins adjacent the side discharge ports on the housing are uniquely structured and positioned to give extended wear and optimum results.
