Two steps of ultra-fine grinding were performed in order to achieve the desired size (<10 micron). The first grinding step includes grinding coarse feed less than 6630 microns. The se- cond grinding step as regrinding process was carried out on the fraction less than 45 micron.

The ultra-fine grinding process is characterized by a high solids concentration and the presence of excessive fines, which are two of the primary factors leading to the formation of agglomerations or flocculations and hence the development of a yield stress of slurry.

The faster and fine grinding of the product is facilitated by the sharp blades that ensure uniform grinding without leaving behind any …
