Advances in Materials Science and Engineering Hindawi

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

In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate. The operator or control system can then focus on adjusting the new ore feed rate, mill density etc to achieve the desired grind, therefore always maximising throughput at the target grind for the ore characteristics and available power.
