  • Industrial versus Laboratory Clinker Processing Using

    2015-12-15 · 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

    2015-10-1 · The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact laboratory-grinding mills operated for given time interval do not consider the effect of circulating load thereby leading to increased specific energy consumption (Ec) with excessively wide cement particle size distribution (PSD) curves.
