In mining industry ball mills normally operate with an approximate ball charge of 30 with a rotational speed close to 11 rpm. The mill is fed at one end of the cylinder and the discharge
Crushed ore is fed to the ball mill through the inlet a scoop small screw conveyor ensures the feed is constant. For both wet and dry ball mills the ball mill is charged to approximately 33 with balls range 30-45. Pulp crushed ore and water fills another 15 of the drums volume so that the total volume of the drum is 50 charged.

The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials with uniform product fineness and saving power.
Oct 12 2017 The ball charge of a SAG mill is about 29 to 30. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material And if extreme fineness and refinery are required then rotation go on continue.
Abstract Ball mills like other comminution devices consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a .
Jan 14 2019 Ball mill introduction. Structurally each ball mill consists of a horizontal cylindrical shell provided with renewable wearing liners and a charge of grinding medium. The drum is supported so as to rotate on its axis on hollow trunnions attached to the end walls attached figure 1 ball mill.
