Dispersion is the major factor to influence the behavior of calcined kaolin in the vibrating mill. The dispersion degree of powder affects not only the fluidity of the powder, but also the efficiency of the grinding. Organic and inorganic aids are used to promote the dispersion degree of powder in the vibrating mill. All of the aids can improve the dispersion degree.
