The ball mill contains materials meant for crushing and grinding, such as balls of ceramic, small rocks, or balls made from stainless steel. the internal device of the ball mill grinds material into powder-like substances, and can rotate continuously for optimal grinding and refinery.
The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific impact energy of the balls calculated from discrete element method simulation. this relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy.
Features that cannot be accessed this way, cannot be cnc machined. there is an exception to this rule: undercuts. we will see how you can use undercuts in your designs in latter section. a good design practice is to align all features of your model (holes, cavities, vertical walls etc) to one of the 6 main principal.
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.
