slurry segregation, the representation parameters of gradation, i.e., average grain diameter and particle size distribution index, were established based on the Fuller formula. Eleven types of gradation based on Weymouth gradation theory were used for segregation test to study the range of particle size distribution index. Solid materials from a certain mine in Yunnan Province were used......
