WEAR TIP HOLDER FOR VSI CRUSHER, AND METHOD OF REDUCING WEAR OF VSI CRUSHER ROTOR

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 for mounting the wear tip holder (32) to said rotor wall, the mounting plate having a mounting face for facing the rotor wall to which it is to be mounted; and, opposite the mounting face, a wear face for facing the interior of the rotor; a wear body, connected to said mounting plate, the wear body being provided with an elongate wear tip recess for holding the wear tip; and at least one material retention groove (58) extending along the wear tip recess at a position upstream, as seen in a direction of an intended flow of material to be crushed, of the wear tip recess, the material retention groove (58) having an upstream groove wall and a downstream groove wall, said downstream groove wall forming an acute angle with the wear face for retaining material (70) to be crushed.
