ball mill efficiency calculations libya
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Apr 19, 2013· About 60 years ago, Fred C. Bond, George Krouse, and a few others involved in comminution research conducted some preliminary studies on low filling level of grinding media in laboratory ball mills. Initial indications were that there was a very good possibility for increased efficiency if ball mills were run with drastically reduced filling ...

Both ball mills and HPGRs are typically used in closed circuit with classifiers. There is a general consensus within the industry that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit ball mills.
ball mill circuit "classification system efficiency" (CSEff). It is the percentage of "coarse" material in the ball mill, relative to the target grind size, typically the circuit target P80. The "coarse" material is targeted for further grind-ing, while the "fines" have reached target product size or finer.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables …
