Large Ball Mill Scale-Up Factors to be Studied Relative to

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.

What is Slurry Volume? - Definition from Petropedia

Slurry 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.

Effects of slurry pool volume on milling efficiency

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. •
