Chat Online2 | model predictive control for sag milling in minerals processing ore from primary crushers is combined with water in the mill where rotation causes the grinding media and the ore to be drawn upwards with the mill liners and tumble, causing fracturing in the first instance, followed by further grinding.Mills can be open or closed circuit.
Chat OnlineThe autogenous/semi-autogenous grinding mills are in most cases used as primary crushers.Ag crushers use the ore exclusively as their grinding media.In case the hardness and the abrasiveness of the ore is not suitable enough to carry out the grinding process, steel balls are added in-order to assist the process; these are called sag crusher.
Chat OnlineGrinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition.The two main objectives for a grinding process are: to liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation.
