Understanding the SAG Mill in Copper Ore Mining
The Autogenous Mill, also known as AG Mill, is a type of grinding mill used in the mining industry This machine uses ore and rock itself as grinding media to perform its job Unlike other types of mills that use steel balls or rods for Ball Mill Introduction There are three main stages to mineral processing in the mining industryThese are: Comminution (crushing and grinding); Beneficiation (separation and concentration); Smelting and refining; Ball mills are Ball Mill (Ball Mills Explained) saVRee saVRee2015年7月29日 As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill This water is one of the main controls that you have over your grindEffect of Water Density on Grinding Mill 911Metallurgist2024年4月26日 These mills utilize the ore itself as the grinding media, reducing the need for additional grinding media AG/SAG mills are typically used for coarse grinding, where large pieces of ore are efficiently broken down The grinding process reduces the ore size, which enhances the efficiency of subsequent beneficiation processes by increasing the Iron Ore Processing: From Extraction to Manufacturing
