  • Grinding Mills Ore Capacity

    The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

  • Ball Mill: Operating principles, components, Uses

    A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.

  • Fine Grinding Hammer Mill

    Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill's grinding chamber.

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
