Abstract
A rotary table for an impact crusher has upper and lower table plates grooved to receive restraining lugs on impeller shoes which are clamped between the plates. The grooves also receive the restraining lugs of segmental wear plates which are held in place, vertically, by having end portions fitting in notches formed conjointly by shoulders on the impeller shoes and the inner faces of the table plates. The latter and the shoes have lip portions to shield the outer edges of the table plates from wear.
