Live Chat2018-3-8Ball Mill Energy-Saving Principle Usually ball mill operates at fixed running speed, and the cylinder speed is determined by belt pulley and gear reduction mechanism or hydraulic coupling. The rotating speed of ball mill directly affects the movement of steel balls and the grinding process of material.
Live ChatCrushed 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.

Live ChatAs the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium. For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ...

Live ChatThis additional reduction of 13.50.75 or 14.67 means that the container should theoretically rotate at 4004.67 rpm or about 85 rpm. I measured a speed of 80 rpm- the slightly lower speed due to frictional losses. So basically your final speed will depend on 1 motor speed, 2 your axle and pulley diameters, and 3 your container diameter.
