Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closedcircuit tube mill operating at 90 ton/hr to those determined using a 50liter laboratory mill.
