Case Study - Grinding Mill Bearing Failure - SlideShare

Jul 31, 2013 · The mill rotor bearings, which are mounted in a steel housing, are two (2) cylindrical roller bearings, NU 316 ECM/C3, and one (1) grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two (2) years. Before this time, the mill had no recorded bearing failures (as confirmed by the CMMS).

The operating principle of the ball mill -

This zone is inactive. In cascade mode grinding occurs as a result of crushing and abrasive actions by grinding balls. This mode used in the ball mill with a central discharge. In mixed mode motion of grinding balls participate balls positioned between the outer layers and inactive “core”. The circulation of grinding balls occurs around an inactive “core”.
