We will begin with the mill's bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills, Rod Mills and SAG Mills. Anything gear and pinion really.
Ball Mills Steel Ball Mill & Lined Ball Mill. Since the late 1800s, the ball mill has revolutionized industrial grinding processes, establishing itself as the gold standard in particle size reduction.. The basic construction of a ball mill is a cylindrical container with journals at its axis. Inside this cylinder, grinding media – composed of ceramic, metallic balls, or rods – fills the space.
