The effects of slurry pooling on ball milling have been investigated. Product fineness was found not to be a function of slurry pool volume. High ball filling J and slurry filling 1.0 ≤ U < 1.3 led to high production of fines. From a batch milling perspective, slurry pool is undesirable for effective grinding.

Fig. 2 shows apparent viscosity of slurries at different solid contents prepared by ball-milling (a)–(c) and wet-jet milling (d)–(f), as a function of time. The viscosity of the ball-milled slurries increases rapidly with time. In general, it is known that aggregated and flocculated slurry causes an increase of viscosity. 18 Hence, this rapid increase of viscosity indicates that …

Raw material preparation and mixing. A ball mill wet-grinds the quartz sand with water to a sand slurry. The sand slurry is stored in slurry tanks and pumped into the slurry weighing hopper in the mixer tower. The binders (lime, cement and anhydrite) are stored in silos. It is also possible to mill the anhydrite together with the sand in the ...
