The invention relates to mining industry, in particular to the equipment for grinding minerals, and can be used in rotary and ball mills to protect working surfaces against wear. A lining of end cap of a drum mill comprises lining plates of the same type, a substrate for lining plates of the same type and fasteners of a detachable joint of lining plates of the same type with an end cap. The substrate is made of wear-resistant bimetallic sheet with shape corresponding to the shape of the working surface of the end cap and is turned by its wear-resistant surface toward the lining plates of the same type, the connection of the substrate with the working surface of cap is rigid and with the lining plates of the same type it is detachable, while the detachable connection of the lining plate with cap and end cap has common fastening elements. The invention can slow the rate of wear of lining plates and end cap, increase their service life and overhaul periods, as well as improve the lining of the end cap of drum mill by changing the features of the structural elements of the lining, ensure the fit density of the lining plates to the substrate, exclude entering abrasive material under them. |
