  • Impeller mounting system for centrifugal impact crusher
    Patent number: 6179234
    Abstract: A system for mounting material directing impellers to the table of a centrifugal impact crusher includes an upstanding mounting plate having a slot extending through it which opens out of its top surface. An impeller has a rearwardly facing stob extending from it which slidably fits within the slot. A nub, which does not fit through the slot, is attached to the extremity of the stob and the stob is sized such that the nub and the rear surface of the impeller interact with the mounting plate to prevent the impeller from moving relative to the mounting plate in either circumferential direction. The sides of the slot are angled radially outwardly as they extend downwardly toward the table.
