The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

laboratory ball mill. if the mill diameter is greater than 3.81m. The cylindrical . Feed Characteristics . The laboratory ball mill was designed for grinding limestone, meaning that the work index required for the specific power calculation was assumed to be the work index of limestone, which is 11.6 KWh/t, with a specific gravity of 2.6 g/cm. 3
However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill
