Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 .
This is important as if you have not seen if yourself, you can not trust it is really 10mm. There should be no scats at 10 mm unless you are using much too small a grinding ball or the mill charge is much too low. For example, I was told by a client his ball mill feed was P80 = 9mm but when I went to look at the feed belt, I saw this below.
