Mill (grinding) - Wikipedia

with W as grinding work in kJ/kg, c as grinding coefficient, d A as grain size of the source material and d E as grain size of the ground material.. A reliable value for the grain sizes d A and d E is d 80.This value signifies that 80% (mass) of the solid matter has a smaller grain size. The Bond's grinding coefficient for different materials can be found in various literature.
