microns The roller mill’s ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste as shown in Figure 1 The mill’s controlled reduction action requires less energy than other grinding methods improving
The grinding jars of the mixer mill MM 500 vario 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
The mill is filled with a suitable grinding media and the area between each disc is essentially an individual grinding chamber As a result the mill is effectively 8 grinding chambers in series The media is set in motion by the action of the grinding discs which radially accelerate the media towards the shell
