Abstract: The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact crushers caused by earth aggregate flows during operation of impact crushers. The present invention includes a central feed body that has hard material rods fixed therein to reduce wear. The hard material rods extend above a top surface of the central feed body. The exposed top surface of the central feed body is impregnated with a plurality of cemented carbide particles. The cemented carbide particles form an upper composite matrix that helps to reduce wear and the premature wash out of the hard material rods integrally cast within the central feed body.
