Abstract.

This paper considers problems on ensuring durability of rubber linings in the ball drum mills. The article describes basic character and types of the rubber lining wear that arises during operation of the mill, and focuses on the most pressing types, which significantly affect the lining durability such as hydro-abrasive fatigue wear forming a wavy surface of material.

Methods for and results of determining a degree of a material wear by energy fracture criterion are presented. Fracture energy per volume unit of material caused by abrasion and fatigue wear has been calculated. It is proposed to use the findings for calculating durability of rubber linings.
