angle of breakage in ball mill

Ball mill Wikipedia

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silies, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.

Mill. This is called as the "break point‖ or "angle of break" because it is measured in degrees up the periphery of the Mill from the horizontal. The most desirable angle of break ranges from 50 to 60 degrees from the horizontal to accomplish the cascading and sliding action for most grinding and dispersing problems.

Pharmaceutical Technology: PRACTICAL I : BALL MILLING

Dec 24, 2013 · 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.
