This feature provides improved grinding efficiency, whilst the integrated classifier simultaneously provides more control over the particle size distribution than is the case with a regular/standard impact mill. Available in a range of sizes, the mill is designed for throughputs typically between 1kg and 6 tonnes per hour and is capable of reducing particle size to below 10 microns.

grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light emitting diode, phototransistor and video photographs were used to determine the load orientation in terms of toe and shoulder positions. A load beam

which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c.
