Retsch XRD-Mill McCrone Retsch Mill NEW
"The XRD-Mill McCrone was specially developed for the preparation of samples for subsequent X-ray diffraction (XRD). The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as R&D.
Because of its unique grinding motion, the XRD-Mill McCrone is particularly effective for this analytical method: The 48 cylindrical grinding elements grind the samples gently via friction. The result is 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, a premise for meaningful X-ray diffraction.
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 grinding time for optimum micronization is between 3 and 30 minutes. A typical sample volume is between 2 and 4 ml." (RETSCH)

"The XRD-Mill McCrone carries out size reduction mainly by friction. 48 cylindrical grinding elements are placed into the grinding jar in eight rows of six elements each.
During operation, the jar’s circular motion causes the elements to grind the sample from < 0.5 mm to the low μm-range (typically < 10 μm).
Thanks to the very gentle size reduction process, the crystal lattice of the sample is preserved. This makes the XRD-Mill McCrone the instrument of choice for the sample preparation for subsequent X-ray diffraction analysis." (RETSCH)
