Ball Mills - an overview ScienceDirect Topics
Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64.

An analysis of mill grinding noise - ScienceDirect
The role of the ore in absorbing noise energy is suggested as a possible control variable for the grinding process and as an indicator of product size distribution. The relationship between ore types and mill noise is also examined and, under conditions of wet grinding, it is demonstrated that mill noise analysis can indicate ore type and may have a possible use as a grindability-type parameter.

2009-7-1 To this end, a disturbance observer based multi-variable control (DOMC) scheme is developed to control a two-input-two-output ball mill grinding circuit. The systems considered here are with lumped disturbances which include external disturbances, such as the variations of ore hardness and feed particle size, and internal disturbances, such as model mismatches and coupling effects.

Ball Milling - an overview ScienceDirect Topics
Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force. In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and compression force

Ball Rod Mill Density - How Water Impacts Grinding
2015-8-6 So as you add water, it will be coming out of the mill at the same volume, earring the ore with it. If the rate of flow is too great the ore will not get the opportunity to be ground before all the fine material has been washed away. Soon there will only be the large and intermediate size of feed left in the mill.
