Controlled cascading waterfall technology of crushing raw ...
Ratio of ball mills loading The first position of the switch corresponds to the purely "waterfall" mode (95 % of the critical speed), the last to the purely "cascade" (50 % of the critical speed), the remaining positions are intermediate high-speed modes [2]. The operating time at any of the eight steps was recorded by a manual stopwatch.

How Ball Mills Lifter Bar Affects Charge Motion
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 operating principle of the ball mill
In cascade mode grinding occurs as a result of crushing and abrasive actions by grinding balls. This mode used in the ball mill with a central discharge. In mixed mode motion of grinding balls participate balls positioned between the outer layers and inactive "core". The circulation of grinding balls occurs around an inactive "core".

Pharmaceutical Technology: PRACTICAL I : BALL MILLING
A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other.
