  • 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.

  • US4194710A - Tumbling mill - Google Patents

  • Particulate Science and Technology - tandfonline.com

    In a tumbling mill, comminution starts by abrading the irregular edges of particles. Particles lose their edges and rough surfaces to become more rounded by comminuting irregular edges. The secondary media like steel balls and/or pebble ports may be used to modify size distribution of output particles.
