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.
Today ConcCare ® M & GA series of grinding aids are in use in several cement, carbonate, phosphate, bauxite, ceramic, kaolin, silica and barite plants in many countries around the globe, generating excellent results with respect to their technical performance and the economic savings.
Grinding markedly affected the crystalline structure of kaolin regardless of chemical treatments. For samples modified with DMSO or KAc, the intensity of the peaks in the XRD patterns decreased with grinding time and after 30 min a broad peak with a very small intensity remained ().This phenomenon was assigned to the degradation of the crystalline structure of kaolin.
where h is the depth (or height) of penetration during the time t, - is the surface tension of the wetting liquid, - its viscosity, - the wetting angle, r - mean radius of capillaries, C - structural coefficient, …
