There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The cataracting motion, on the other hand, causes the particles to break under high-impact forces.

The problem with your charcoal crushing phase of the operation is that the speed of the concrete mixer is appropriate for mixing concrete, and not for operation as a ball mill. Mixing mills operate in the "Cascading Mode", where the materials tumble over themselves. Grinding mills operate in the "Cataracting Mode."

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

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 predominantly the cascading regime, the cataracting regime or the centrifuging regime.

For example, at 60% critical speed, the charge is very clearly divided into cascading and cataracting zones in the case of a large mill, while for the same speed only a cataracting zone exists in a small mill. Moreover, the laboratory-scale mill uses a ball size distribution with a smaller top ball size, which also alters the breakage regime in ...
