ball mill and particle size

ball mill and particle size

industrial use horizontal rotating cylinders that contain the grinding media and the particles to be broken. the mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of the when the force of gravity exceeds friction and centrifugal forces.

  • ball mill - wikipedia

    a ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls, flint pebbles, and stainless steelballs. an internal cascading effect reduces the material to a fine powder. industrial ball mills can operate continuously, fed at one end and discharged at the other e…
