The new MM 500 Mixer Mill from Retsch is a compact, versatile bench-top unit which has been developed for dry, wet and cryogenic grinding of small sample amounts.

The MM 500 Mixer Mill will mix and homogenize powders in only a few seconds, is simple to use and is the perfect combination of a classic mixer mill and a planetary ball mill. Retsch Mixer Mills are true all-rounders which are used in laboratories all over the world.

For heavy milling over several hours where high energy input is required to obtain particles sizes < 1 µm, (eg. for mechanical alloying or chemical reactions), planetary ball mills have to date been the preferred solution. Despite their benefits for this type of application, they have a major drawback as cooling breaks are required during processing and they are not as easy to handle as mixer mills.

The new MM 500 Mixer Mill features a maximum frequency of 35Hz. It is the first mixer mill on the market which delivers the crushing power required to produce particles in the nanometer range. Accommodating 2 grinding jars sized 50 ml, 80 ml or 125 ml with an ability to run continually for up to 99 hours and to take interim samples in situ without removal of the jars, the MM 500 a real alternative to planetary ball mills where breaks in processing are required to avoid sample heating.
