    Ball Mill Wear Test 911 Metallurgist

    Jul 01, 2017 The abrasive wear of balls that results from the milling of ore is the major wear loss in most minerals processing plants. During the wet milling of ores, abrasive wear is combined with corrosion. Abrasion and corrosion are synergistic a corroded surface is more easily abraded than an abraded surface and an abraded surface is more easily corroded than a corroded passivated surface.

    Dec 08, 2009 Re how to estimate the wear rate for Ball mill. Hey 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.
