PRINCIPLE: A ball mill 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.

#### The operating principle of the ball mill Primo Pizza

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

#### Pump and Cyclone Design/Optimization to Maximize

One of these, “Circuit Classification System Efficiency” (CSE), is the fraction of “coarse” material inside the ball mill upon which grinding energy is deliberately expended, versus the remaining fraction of “fines” or finished size material inside the mill, upon which grinding energy is wasted (on over-grinding).

#### Copper Processing: The Quest for Efficiency at Scale

2020-4-8  Then, in the finer size ranges, where something like a HIGmill or a SMD are used, it’s all about energy efficiency. It’s much more efficient to grind to very fine or ultra-fine levels using these technologies that have very small media than in a ball mill where a lot of the energy is wasted in lifting the media, as opposed to grinding.
