HOLDER OF WEARING TIP FOR IMPACT CRUSHER WITH VERTICAL SHAFT, SET CONTAINING HOLDER WEARING TIP, AND METHOD OF REDUCING WEAR RATE OF WEARING TIP HOLDER Russian patent published in 2016 - IPC B02C13/18 B02C13/28 

FIELD: disintegrators and devices for crushing.

SUBSTANCE: group of inventions relating to holder of wearing tip, kit containing such holder and method of reducing wearing tip holder wear rate can be used in impact crushers. Holder comprises mounting plate for holder attachment to wall of rotor. At that, mounting plate has mounting surface with possibility of access to wall of rotor and wearing surface with possibility of access to inner part of rotor. Wearing surface is provided with at least one hole to hold on wearing surface (54) at least one wear-proof insert and material subject to crushing. Set comprises holder and at least one wear-resistant insert, which is installed in at least one hole, retaining material. Insert is made from material with higher wear resistance than wearing surface mounting plate. Method consists in fact that gripped at least one wear-resistant insert and material to be crushed in at least one retaining material hole arranged on wearing surface of mounting plate.

EFFECT: group of inventions increases service life of crusher between stops for maintenance.
