Abstract
A distributor plate assembly for a vertical shaft impact (VSI) crusher is optimized for abrasion wear resistance. The distributor plate includes a plurality of plate segments, each segment being formed from a main body of ductile iron alloy having cemented carbide granules embedded within the iron alloy.
Claims16
A distributor plate assembly releasably mountable to protect a disc of a rotor within a vertical shaft impact crusher from material fed into the rotor, the assembly comprising:
- a plurality of segments, each segment including a main body having a contact surface positioned in an upward facing direction arranged to contact material fed into a rotor, the main body being ductile iron alloy incorporating nodular graphite and cemented carbide granules embedded within the iron alloy, wherein the main body includes outer edges that form a perimeter region, the main body being modular, wherein the plurality of segments is arranged in a circumferential direction around a central axis;
- and
- a first insert mounted in the main body of at least one of the plurality of segments such that an upper surface of the first insert forms a part of and is coplanar with the contact surface of the main body, the first insert including at least two radially outward facing edges, the at least two radially outward facing edges of the first insert forming a part of and extending only to the perimeter region of the main body, wherein each of the at least two radially outward facing edges of the first insert is co-aligned with a respective outer edge of the perimeter region of the main body, and wherein the at least two radially outward facing edges of the first insert do not extend past the outer edges of the perimeter of the main body, the first insert being abrasion wear resistant relative to the main body.
