ABSTRACT:
The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact-type rock-crushing machines caused by earth aggregate flows during operation of impact crushers. The present invention includes a central feed body and impeller shoe that has hard material insert bars fixed therein to reduce wear. The exposed top surface of the central feed body and front face of the impeller shoe are impregnated with a plurality of cemented carbide insert bars. The cemented carbide insert bars form an upper composite matrix that helps to reduce wear and the premature wash out of the hard material insert bars integrally cast within the central feed body.
