wear nozzle support element for a vertical axis impact crusher and method for reducing rotor wear of a vertical axis impact crusher

摘要

A wear tip holder, for holding a wear tip adjacent to an outflow opening of a vertical rotor wall of a rotor of a VSI crusher, comprises a mounting plate (44) for mounting the wear tip holder (32) to said rotor wall, the mounting plate (44) having a mounting face (56) for facing a segment of the rotor wall to which it is to be mounted; a wear face, opposite to the mounting face (56), for facing the interior of the rotor; and a side wall (58, 58a-c) extending between said mounting face (56) and said wear face, the side wall (58, 58a-c) comprising a material retention surface (62, 62a-c) facing, when in use, said rotor wall segment, thereby allowing material to be trapped under the material retention face (62, 62a-c).
