grinding media difference

Grinding Medium - an overview ScienceDirect Topics

The primary difference is a lower degree of size reduction with the smaller 3 mm ball size. Expectations point to smaller grinding media size providing the greater size reduction for a given energy input (Tüzün and Loveday [12], Stehr [13]). With a smaller ball size, the larger is the number of balls and the larger the ball surface area for ...
