  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind and 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

  • A discussion on the measurement of grinding media wear

    A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi autogenous grinding, and therefore nearly 90% of mining operations are users of balls as grinding media [5]. Along the main goals of mineral processing, one must also list the reduction of the
