Pebble mills are similar to ball mill except that the grinding media is closely sized suitably selected rocks or pebbles. The rotating drum causes friction and attrition between rock pebbles (say, quartz or quartzite pebbles) and ore particles. Pebble mill operates at low cost with respect to grinding media, power consumption and maintenance. It has wide application in gold mines.
