Ball Mill - an overview | ScienceDirect Topics
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Wound Rotor Induction Motor with Liquid Rheostat Arcing ...
We operate ball mills with dual-coupled 3500hp 4160v wound rotor induction motors. We have recently experienced frequent arcing of the slip rings which seems to start on the center ring. The arcing damages the ring badly which requires us to shutdown the mill to sand it smooth again.

Wye-Delta Starters vs Softstarters | Mike Holt's Forum
The ball mill when loaded had a very large initial intertia and it needed a high initial starting torqure which was provided by a Liquid Rheostat. Depending on the rate at which the resistance in the Rheostat would change would affect the starting time of this motor and load.
Ball mill - Wikipedia
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

How I built a quick and easy home-made ball mill
They work pretty well in this application. There are a few potential problems. The container lids are not liquid-tight. So use as a rock tumbler would require adding a cork or rubber gasket. Also, a little bit of the plastic does get ground off the inside surface and contaminates the batch being ground.
