Effect of particle size gradation on cwm preparation

In this paper, based on void packing model, the gradation of particle size range for 18mesh∼35mesh, 35mesh∼60mesh, 60mesh∼140mesh, 140mesh∼200mesh, 200mesh∼325mesh, above 325mes were investigated. The results show that lowest viscosity depends on the weight percent of particle and particle size. The priority packed position of particle size is R2 and R6.
