In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material. The experimental parameters that were kept constant in this investigation was the grinding media filling, powder filling and the mill.In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state.

Oct 01, 2020 In this paper, we present a detailed investigation of the dry grinding of silica sand in an oscillatory ball mill. We are interested in the evolution of specific surface area (SSA), particle size distribution, agglomerated SSA and consumed electrical energy as a function of the input grinding.Jul 04, 2017 The breakage distribution function was evaluated from the zero-order fine particle production plots. The results indicated that, similar to the case in dry batch ball milling, the breakage distribution functions are normalizable (that is, independent of the parent size) and independent of holdup in the mill.
