Feed Size VS Ball Size - Grinding & Classification ...

A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi-self locking taper. One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill.

Since sampling of the particle sizes during runs led to significant disturbance of the mill load through loss of fines, mill loads were only sampled at the end of each run. The runs differed in duration, i.e. runs could last 5, 10, 15, 20, 25, 30, 35, 40, 45 or 50 minutes. In all, 63 runs were recorded for the Merensky ore, while 39 runs were ...

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, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
