The mixer mill MM 400 is a compact versatile bench-top unit, which has been developed specially for dry, wet and cryogenic grinding of small amounts of sample. It can mix and homogenize powders and suspensions in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for

Size of the milling balls should not be more than 3-4 orders of magnitude larger than your final grain size you want to achieve. Once you reach this grain size and you want finer powder you have to shift to smaller milling balls. Starting with very small milling balls right from the beginning is not recommended as they haven't

How to optimize a 6 pound ball mill to safely and effectively ball mill homemade black powder. At some point in this pyro-art adventure, we start to hear or get the feeling, that we need a ball mill to grind chemicals very fine or to make high- quality black powder. This project will not attempt to be a comprehensive review of

powder filling ratio and ball filling ratio were investigated. Alumina balls were used as grinding media. Experiments were carried out using the 24 full factorial design. The main and interaction effects were evaluated using the Yates method. Test results were evaluated on the basis of product size and surface area.

The main advantage of a jet mill over other kinds of mills is that you can grind a friable or crystalline material to 1 – 10 microns average particle size. How does jet milling compare with other methods of grinding such as a ball mill or a hammer mill? Any powder that is crystalline or friable can be ground in a jet mill.
