In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 – 30%, similar to that seen in primary grinding. However, for corrosive environments with low abrasion, the high Cr ball can result In Improvements of 50% or more compared to forged steel. This is particularly true for some of the secondary grinding (primary ball …

Sep 19, 2019· Processing. Gold within the ore is very fine-grained, ranging from 150um to less than 10um and commonly less than 40μm. The Cracow processing plant consists of a three-stage crushing circuit, primary andsecondary ballmilling, pre-leach thickening, finegrindingand conventional cyanidation leaching (CIP)

Theball millis a tumblingmillthat uses steel balls as thegrindingmedia. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimizeballcoating, or slurry containing 20–40% water by weight

Grinding balls for miningare generally used to break downsecondarymaterials such as rock, cement and stone during the extraction of ores and metals. AISI steelgrindingballs forball millapplications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95
