Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; 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:
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
Oct 15, 2000· Stainless steel can be gummy enough that coolant may be needed as a lubricant when a ball-nose or other round-profile tool is used. That was the case with this Stavax 420 stainless steel mold core. When dry milling wasn't producing an acceptable surface finish, the operator switched to using liquid coolant and the finish improved.
