AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator Training

millopsmunity.uaf.edu/amit-135/amit-135-lesson-6/What is the difference between a crusher and a grinding media?To produce fines (or filler) from mineral fractions by increasing the specific surface. Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers. Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) Less sensitive to feed composition (critical size material)
