Dec 12 2016 Ball Mill Power Calculation Example A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size
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
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. AGSAG 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.
