HOW BALL MILL WORKS

10 10 2016  The ball mill is a hollow drum closed with loading and unloading end caps filled with grinding media and rotated around its axis.The drum of the ball mill Pic 1 is a hollow cylinder of steel lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
