    Thus it may be necessary to adjust the dosage of the gypsum. Optimizing the dosage and degree of dehydration of the gypsum will mitigate the effects of the particle size distribution on water demand. In order to obtain the greatest benefit from a high efficiency separator the operation parameters of the mill circuit should first be optimized.
