INVESTIGATION OF FEED DYNAMICS IN CLINKER GRINDING

Keywords: Clinker, dynamics, Feed, mill, residence, time. 1.0 INTRODUCTION The main raw material for cement production is clinker. Cement clinker is usually grounded using a ball mill. This is essentially a large rotating drum containing grinding media; normally steel balls. As the drum rotates, the balls cascade and crush the clinker.

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
