A ball mill is a type of grinder used to grind, blend and sometimes for mixing of fmaterials 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.
3C. Moisture Heating and Cooling Many of us have encountered moisture and moisture related problems, whether we are working with raw, coal or finish grinding mills. When we talk about moisture, we also talk about heating (drying) and cooling mill circuits. Mills themselves generate a lot of heat. For ball mills, 90% of the mill motor power gets converted into heat.
