2.10.5 Characterisation of Separator Efficiency in a Ball Mill Circuit 18. Separator efficiency is defined as specific power consumption reduction of the mill open-to-closed-circuit with the actual separator, compared with specific power consumption reduction of the mill open-to-closed-circuit with an ideal separator.

Working Principle of Ball mill: As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either ''open circuit'' or ''closed circuit''. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.

Ball mills, however, are virtually always operated in a closed circuit with some form of classifier. Various types of classifying device can be used to close the circuit, such as mechanical classifiers, hydro-cyclones, etc. The AG/SAG mills can be operated in open or closed circuits. However, even in an open circuit, a coarse classifier such as

Grinding systems are either ''open circuit'' or ''closed circuit.'' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.

The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
