Learn MoreMakokha et al. [20] reported that an increase in the ball mill volume loading tends to increase the slurry turnover time. It reduced the slurry pool volume subsequently lowering the mill discharge

Learn MoreSlurry Density is the ratio of sum of the weight of water and additives to the volume of cement slurry. It is usually expressed in kilogram per cubic meter (kg/m3) or pounds per gallon (lb/gal). In a typical oil or gas well, cement slurry density can range from 1380 to 2280 kg/m3 or 11.5 to 19.0 lb/gal.

Learn MoreThe 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. •

Learn More% total filling and the % solids by weight of the discharge slurry. The ball filling relates to the volume (including voids) that the balls occupy when the mill is completely ground out, ie there is no ore in the mill. This volume is expressed as a % of the total mill volume. Note that these figures should be
