    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 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 rotati When the mill finally goes into operation the structural bolts on mills are exposed to extreme loads during operation and after a period of time they start to relax and loosen off further this can lead in a surprisingly short time to joint leakage and eventually failure. Our aim is to educate mill owners and give them a way to stop this
