A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. ... Vertical roller mill; References This ...

Wet Ball Mill = kg kWh = (A ) ; Dry Ball Mill = kg / kWh = i ; Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media:

More machine operators are familiar with vertical machines, making them easier and less expensive to operate than horizontal models. 6. Material Removal Rate. Because they are more stable and can produce deeper cuts, horizontal milling machines have a much higher material removal rate than vertical mills.

Note that the hardness of these scats is not measured by a Bond BWi because that test crushes everything to minus mm, the maximum size for good ball milling or VERTIMILL efficiency. I do agree that the VERTIMILL power will be lower than a ball mill so there is merit in replacing ball mills with Vertical Stirred mills.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
