Cement Ball Mill Structure When Ball Mill is working raw material enters the mill cylinder through the hollow shaft of the feed The inside of the cylinder is filled with grinding media of various diameters (steel balls steel segments etc ) when the cylinder rotates around the horizontal axis at a certain speed Under the action of centrifugal force and friction force the medium and the
Ball mills are very similar in design and operating concept to rock tumblers which used milling media to polish rocks in a rotating cylinder Ball mill machines usually include a cylinder a motor and crushing media The cylinder is where the crushing happens The material intended for crushing is fed into the cylinder along with crushing media
This project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano powder The cylindrical jar is used as a mill that would rotate the material that about to be ground a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar
