Tumbler Ball Mills. In the tumbler mill shown in Fig. 19, the motion of the balls or rods depends on the rotation speed of the chamber walls. Balls may roll, or "cascade," down the surface of the charge in a series of parallel layers or they may project, or "cataract," into space, falling on the balls and particles at the toe of the charge below.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder.

Introduction: Grinding or milling is a process to break the solid material into smaller pieces or even into powder. It is widely used in industrial to obtain desired size of the product. The size of the product depends solely on the time of grinding and the speed of the grinder. In our experiment, a device known as ball mill will be used.

The mill speed is one of the vital parameters in ball mills, which is normally specified as a fraction of critical speed. It determines whether the load behavior is predo-minantly the cascading regime, the cataracting regime or the centrifuging regime. In general, the industrial ball mills rotational speed operates at 70%~80% of critical

The radius and angle position of the mill charge centre of mass is commonly used for the ball mill dynamic model during start-up. This model considers that the mill load maintains its resting shape and that the mill is lifted to a certain angle depending on the mill speed and existing operating conditions during its rotation [ 3 ].

of the parabolic trajectory of a ball and hence the strike zone on the toe of the mill (Sepulveda 2012). In fact, the best choice of lifter release angle can be determined using single ball trajectories. The best angle corresponds to the trajectory that can be maintained even as the lifter wears out (Royston 2007).
