Apr 16, 2018 In the past few decades, a plethora of research work has been published that dealt with ball mill scale-up. The first systematic scale-up procedure was proposed by Bond. By means of a set of grinding experiments conducted in a laboratory mill a parameter known as “Bond''s work index” is determined.
