XRD-Mill McCrone Laboratory Mill

Description

The XRD-Mill McCrone from Verder Scientific is a specialized grinding mill developed for preparing analytical samples, particularly for X-ray diffraction (XRD) analysis. Its operation is based on a unique frictional grinding principle, utilizing 48 cylindrical grinding elements within a closed vessel. This gentle, grinding-ball motion is highly effective for reducing medium-hard, brittle, or fibrous samples to sub-0.5 millimeter sizes while minimizing damage to the sample's crystal lattice structure—a critical requirement for accurate XRD results. The mill is suitable for both dry and wet grinding applications, serving fields such as geology, chemistry, mineralogy, and materials science. Benefits include short processing times, low sample loss, minimal cross-contamination between runs, and the production of a very narrow, reproducible particle size distribution. With compact bench-top dimensions of 205 by 520 by 155 mm, it is a practical tool for both quality control and research and development laboratories.
