Mar 10, 2020 How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates either on its vertical or horizontal axis. As 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
A ball mill is a type of grinder used to grind and blend bulk material into QDs nanosize using different sized balls. The working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.
