A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in
