Abstract
A plate for reducing wear by a material flow, according to the present invention, includes a body having at least one surface exposed to a material flow. At least one bore is formed in the body through the surface of the body exposed to the material flow. Also included is at least one rod which has a distal end and a proximal end. The rod is immovably secured in the bore. The distal end of the rod is positioned a distance beyond the surface of the body exposed to the material flow.
Claims5
An impeller for a centrifugal rock crusher, said impeller comprising:
- a body having a first surface for receiving and hurling aggregate toward anvils and a second surface for mounting said body on a rotatable impeller assembly, and wherein said body has a plurality of bores formed therein through said first surface;
- and
- a plurality of rods, each rod having a distal end and a proximal end, said proximal ends of said rods being inserted in said bores, and said proximal ends being immovably secured in said bores, and said distal ends of said rods being positioned a distance beyond said first surface of said body, and wherein said rods are interference press fit into said bores, such that said rods are secured in said bores by pressure.
An impeller for a centrifugal impact crusher, said impeller comprising:
- an impeller shoe body having a first surface for receiving and hurling aggregate toward anvils, said first surface being exposed to aggregate flow during operation of said impact crusher, and means for mounting said impeller shoe body on a rotatable impeller assembly, and wherein said impeller shoe body has a plurality of bores formed therein through said first surface;
- and
- a plurality of rods, each rod having a proximal end and a distal end, and wherein said proximal ends of said rods are interference press fit in said bores, such that said rods are immovably secured in said bores, with said rods being in compression within said bores, and wherein said distal ends of said rods are positioned a distance beyond said first surface of said impeller shoe body.
