Comminution - an overview | ScienceDirect Topics

Solving Eq (51b) for n=3/2 gives the same form as Eq (54) with the constant 2 K ahead of the bracket In effect the 2 K is replaced by (10×Wi), which is convenient because Wi becomes equal to W in the case of grinding from a theoretical infinite feed size to 80% passing 100 µm The Bond model remains the most widely used, at least for the “conventional” comminution equipment in use ,
