<p>IMPROVEMENTS IN CENTRIFUGAL IMPACT ROCK CRUSHERS Centrifugal impact crusher machines have a rotating impeller table on which are mounted table liners and shoes for directing rock, or other material to be crushed, dispersed by a centrally mounted feed cone positioned on the rotating table outwardly against stationary anvils. The herein disclosed machine is comprised of impeller shoes which are removably attached to table mounted brackets by means of pins for facilitating quick easy removal and which have tapered working faces for promoting even wear and longer life. The impeller table liners are portioned respectively into first segments, which are positioned beneath and forwardly adjacent to their associated shoes and held down by the weight thereof, and second segments having lips which are arranged for fitting under the table feed cone, thus permitting these former segments to be replaced without need for replacement of the latter segments and both segments to be removed quickly. The second table liner segments include inclined ramp portions located adjacent to the leading edge of the first segments for directing the rock upwardly from the table face into the faces of the shoes thereby lessening wear of the uncovered portions of the first segments and increasing the efficiency of the shoes.</p> |
