METHOD FOR VERIFYING THE FILLING LEVEL OF COAL IN A BALL MILL

摘要

The method for verifying the filling level in a ball mill fed by material which is to be ground and provided with a rotationally mounted drum on two distant bearings consists in measuring the weight of the drum with the aid of bondage-gage weighing sensors (11-16) disposed underneath the bearings supporting the drum of the mill and in comparing the measured weight with a set value that is pre-established with a view to regulating the supply of material which is to be ground to said mill. According to the inventive method, the weight measured by a first weight value (FV) representing the vertical component of the effort created by the rotational driving torque of the drum is corrected before the comparison step.
