particle size down to approximately 1 millimeter (mm) (0.04 in.) in diameter. Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used.

The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times. The PM 400 is a robust floor model with 4 grinding stations. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.

It was also observed that a binary mixture resulted in more material reporting to the required product fineness compared to having two mills in series with one having 20 mm and other 10 mm ball size. For the finer feed material, it was also observed that a binary mixture again resulted in more material reporting to the required product

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these factors are significant.
