when ball milling, always use about balls by volume. make sure the drum isnt going too fast--say revolutions per second, max. It helps to glue a couple of wooden paddles inside the drum to aid mixing. If the drum goes too fast, it will no longer tumble and drop the balls, but just throw things outward due to centrifugal force.ball mill is a kind of grinding mill used in the mineral processing, which is to further grinding the material fitness to the appropriate particle size that meets the industrial requirement after the crushing process. At present, the ball mill machine is widely used in mine, cement, silicate products, building materials and other fields. structure of ball millfeb 18, 2020 ball-nose end mills. ball-nose end mills have a dome-shaped tip. these excel at high-detail contours like relief artwork or mold and die making, but have what is known as scalloping. since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth
