Industrial versus Laboratory Clinker Processing .

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 ...

Effect of grinding aids in cement grinding

The effect of grinding aid in clinker grinding Figure 3 shows the size distribution analysis for various grinding additives at 0.1% dosage. Although the particle size analysis has resulted in the increasing of coarser particles with the increasing concentration of TEA, it shows that the powder is free flowing with higher concentration of TEA. The increasing of coarser size is because of the ...
