Optimization of Solids Concentration in Iron Ore Ball

Jun 18, 2019· Consider the mass of material in a ball mill to be divided into n narrow size intervals with maximum size x1 and minimum size xn+1.The ith size interval, bound by xi above and xi+1 below, contains a mass fraction of material mi(t) at time t. A di erential mass balance for the ith size interval yields the kinetic model [9]: d[H mi(t)] dt = Si(t

AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 K√F dB = ball size (cm)
