Retsch has developed the Mixer Mill MM 500, which it says is the first ball mill with a frequency of 35 Hz which produces enough energy for wet grinding of samples down to the nanometer range.
The company says that the mills is suitable for long-term grindings of several hours with high energy input to obtain particles sizes <1 µm for mechanical alloying or chemical reactions. Due to only warming effects, no cooling breaks are required and operation and handling are reportedly more comfortable than with planetary ball mills.
The benchtop unit is also suitable for dry, wet and cryogenic grinding of sample volumes up to 2 x 45 ml in one working run. It can handle grinding jar volumes of 50 ml, 80 ml, 125 ml in four different materials.
