r Journal of Physical Chemistry

Most ultrafine grinding processes are characterized by a high solid content and the presence of excessive fines. These are two primary factors leading to the formation of agglomerations or flocculations developing yield stress of slurry. The use of an optimal dispersant can change the surface nature of particles in the ground slurry creating inter-repulsive forces among particles [19-26]. This ...
