Abstract
A grinding mill apparatus is disclosed comprising a grinding mill having a feed end head and a discharge end head and a shell disposed between said heads and secured thereto for rotation with the head. A feed end bearing and a discharge end bearing are provided for supporting the feed end head and the discharge end head for rotation about a generally horizontal axis. The bearings include a bearing element which pivots with the heads with the amount of pivot proportional to the increase or decrease of charge level within the mill. A proximity probe is secured to a stationary surface and aligned with a target which is secured to the bearing. The proximity probe detects changes in gap size between the probe and the target and generates a signal indicating an increase in charge level or a decrease in charge level within the mill. The reading from the proximity probe together with a reading of power requirements for the mill indicate whether a charge level within a mill is approaching a maximum operating charge level for the mill.
