Mill (grinding) IPFS
SAG is an acronym for SemiAutogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. SAG mills use a ball charge of 8 to 21%.

2019726&ensp·&enspIn all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
How ball mill works? energosteel
In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption. Drum mills have one grinding chamber (short and long ball mills) and two or more grinding chambers (long and pipe ball mills). Singlechamber continuous mills are the main equipment at mining and processing plants.
