Retsch XRD-Mill McCrone – preserving the crystal lattice

The Retsch XRD-Mill McCrone has been developed for the preparation of samples for subsequent X-ray diffraction (XRD).  Its unique grinding motion is particularly effective for this analytical method due to the grinding elements causing linear contact blows as well as planar shearing. This results in a short grinding time with almost no sample loss and an exceptionally narrow particle size distribution.  The crystal lattice is almost entirely preserved during grinding operation.

The grinding vessel consists of a 125 ml capacity polypropylene jar fitted with a screw capped gasketless polyethylene closure. The jar is filled with an ordered array of 48 identical cylindrical grinding elements, available in agate, zirconium oxide or corundum.

The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as research and development.
