Mixer Mill (Net weight – 60 kg NANO)

The Mixer Mill (Net weight – 60 kg NANO) is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 35 Hz, it generates enough energy to produce particles in the nanometer range.
The Mixer Mill (Net weight – 60 kg NANO) is a unique mixer mill in the market to provide a real alternative to grinding in a planetary ball mill – with more comfortable handling and less warming effects.

FUNCTIONAL PRINCIPLE

The grinding jars of the Mixer Mill (Net weight – 60 kg NANO) perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also, the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample. The degree of mixing can be increased even further by using several smaller balls.
