The amps in a mill are a derivative of the kg/kwh, which is the ultimate most important indicator for steel balls consumption. when one make the integration of amps vs. time one obtains the kwh, so those parameters are proportional, but also the kwh gives an indication of the mill efficiency. the balls coating is an interesting concept too.

Estimating ball consumption - molycop. sep 17, 2018 for an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kwh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.Grinding ball consumption in cement mills typical specific energy consumption is 30 kwh/t in grinding of cement. barmac-type crushers found application as a pre-grinder in cement grinding circuits operating with ball mills to reduce the specific energy consumption of ball mill-grinding stage [ 2 ].author: m rden gen cited by:1publish year:2016.

A ball mill is a drum-grinding unit where balls from solid materials steel, iron, hard alloys, ceramics, etc are used. most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. then the grinding media are again below.
