The unique grinding action of the mill rapidly reduces troublesome 0.5mm particles to submicrometer sizes required for quantitative and qualitative analytical methods. Forty-eight cylindrical grinding elements produce both line contact blows and planar shearing, in contrast to the random contact blows of a conventional ball mill.
Slurry grinding by either corundum or agate grinding elements, both included with the mill, is the preferred method in most laboratories. Liquids used for slurry grinding include water, deionized water, isopropyl alcohol, or cyclohexane. Isopropyl alcohol and cyclohexane are recommended for clays.
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 10-minute grind and if it is not fine enough, put it back on and grind for an additional 5-10 minutes depending on size to be achieved. Many samples are ready after 10 min. and few need more than 35 min. grinding time.
The standard Mill package includes built-in process timer, 2 sets of agate grinding elements in jars with lids, loading device, extra mounting set, and pouring cap.
