• Industrial versus Laboratory Clinker Processing Using

    Dec 15 2015 · The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. 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 closed-circuit tube mill operating at
