circulation, including the rejects, act as a dilution for moisture when mixed with the fresh feed. This facilitates material handling in case of raw mix, but also allows control of the moisture content into the mill. Such an arrangement allows for an easy and effective incorporation of large amounts of wet additives in the cement mill circuit
