LONG ELEMENT-INSERT FOR GRINDING ROLL COMPOSED OF TWO MATERIALS Russian patent published in 2014 - IPC B02C4/30 

FIELD: process engineering.

SUBSTANCE: set of invention relates to grinding of materials. Elongated element-insert 1 for grinding roll 6 for operation with high-intensity wear comprises mid part from first material of first hardness extending along element-insert 1 and body from second material of second hardness. Said body covers directly said mid part. First hardness is higher than the second one. Invention discloses also cartridge 5 for grinding roll 6 with multiple described elements-inserts 1, grinding roll pat with multiple elements-inserts 1 or multiple cartridges 5, grinding roll 6 with multiple parts 8 or cartridges 5, and grinding machine including at least one grinding roll 6. Besides, this invention covers the method for improvement of high-pressure grinding roll wear resistance.

EFFECT: higher wear resistance, more reliable clamping of inserts, decreased degradation of inserts.
