Mixer Mill MM 400 Function Principle - RETSCH

The grinding jars of the mixer mill MM 400 perform radial oscillations in a horizontal position. More info: https://www.retsch.com/mm400 The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the jars and pulverize it. Also, the movement of the 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. If several small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption. #mixermill #ballmill #samplepreparation #qualitycontrol
