The bond ball mill grindability test (bond, 1952, 1961) gives the bond ball mill work index. this index expresses the resistance of a material to ball milling; the higher the value of the bond ball mill work index, the more difficult it is to grind the material using a ball mill. this index is widely used in the mineral industry.
The grinding operation in a mineral processing facility typically consumes the majority of the energy used. in addition to energy, these mills consume special steel rods or balls as well as the steel mill linings. combining all of these factors we see why grinding is one of the highest costs involved in mineral processing. keeping these costs.
The sag mill liners wear will increase by 15% due to the impact of medium such as steel ball during the sag mill operation. later, people were inspired by the semi-automatic grinding mill, adjusted the amount of medium in the semi-automatic mill, and evolved our most common ore dressing mill, ball mill and rod mill.
