  • A Review of Advanced Ball Mill Modelling

    A more in-depth look at ball mill operation clearly suggests the richness of the information hidden behind the value of specific energy in an operation which should be regarded as merely an average number. The emphasis on this number suggests in principle that it would not mat-ter how the material receives energy just the amount.

  • THE OPTIMAL BALL DIAMETER IN A MILL

    The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding. In both cases the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992 Katubilwa and Moys 2009 Erdem and Ergun 2009).

  • Quantifying the energy efficiency of fine grinding

    May 14 2020 · Two of the most popular methods for estimating grinding energy requirements are the Bond operating work index (OWi) and the Morrell specific comminution energy method. Both relate the comminution energy to the reduction in the 80 th percent passing size of the feed and product streams (F 80 and P 80). An important condition that needs to be met
