Estimate ball mill wear

Secondary Grinding Ball Mills experience 1-2 years of liner life, depending on tonnage/ball size. Normally Lifter to Plate ratio is 1:2.Tertiary Grinding Ball Mills experience up to 4 years of liner life. Since, all the mills are unique in their operation and the practical sense in which they run, we do wear measurement during every shutdown

    Dec 08, 2009 Re: how to estimate the wear rate for Ball mill. Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated

    Predictive Model for Ball Mill Wear: Canadian

    Jul 18, 2013 Abstract. Ball mills, characteristic of the mineral processing industry, are used to reduce ore from one size distribution to another. Wear is associated with comminution mechanisms found in the ball charge which in turn affects grinding performance. In this work, ball mill wear, as a function of mill operating variables, is determined using a

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones

    We have analytically derived a mathematical model of energy-saving ore grinding by a ball mill with a three-phase motion of grinding bodies, invariant to a change in the length of rods during wear. The model can estimate the energy efficiency of grinding larger pieces of ore based on the resulting volume of crushed large-lump material
