Ball Mill

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.Closed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction. a typical closed system grinds the ore between two to three times . hydro-cyclones installed directly after the ball mill ensure only over-sized material is returned to the ball.
