Nov 24, 2010· A ball mill is also commonly employed for fine grinding. In a ball mill, grinding energy is transferred to materials through media such as balls, rods, pebbles, by moving the mill body . For both types of mills the mechanisms by which particle size is reduced follow the same principles.

This was then followed by separation of the product from the grinding media on a wire mesh. The mill product was then taken to a jones rifle splitter and homogenously separated into measured 100 g samples for sieve analysis. Using the 850 + 300 μm size class material, this procedure was repeated for all the grinding times considered.
XRD–Mill McCrone
The mill can accept up to approximately 4mL of material, although optimum grinding efficiency is usually achieved with a 2mL sample. The advantage of our mill is that the analyst can examine the sample after a 10minute grind and if it is not fine enough, put it back on and grind for an additional 510 minutes depending on size to be achieved.
