HOLDER FOR WEARABLE PLATE OF IMPACT CRUSHER WITH VERTICAL SHAFT AND METHOD OF REDUCING WEAR OF ROTOR OF SAID CRUSHER Russian patent published in 2016 - IPC B02C13/28 

FIELD: machine building.

SUBSTANCE: group of inventions intended for use in impact crusher with vertical shaft. Holder (32) of wearing plates is located adjacent outlet vertical wall of rotor crusher. Holder comprises a mounting plate for its installation on wall and wearable body. Body has elongated recess for retaining plates. Plate has a mounting surface for access to rotor wall and opposite wearing surface facing inside rotor. Holder comprises at least one retaining material groove (58). Groove extends along groove plate in position upstream recess. Groove has upstream and downstream walls. Located downstream of groove wall forms a sharp angle with wearing surface to hold subject to crushing material (70). To reduce rate of wear of rotor, material to be crushed is caught in groove.

EFFECT: reduced slipping of layer of material from rotor wall reduces a risk of wear and prolongs service life of crusher.
