Sieve Screens
Woven Wire Mesh Sieves – other frame diameters
The well-proven RETSCH sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the sieve fabric is precisely joined into the frame and tautened. RETSCH test sieve provides a clear and accurate labeling with full traceability.
The sieves can be easily combined with all other sieve brands. Each sieve that leaves our company comes with a test report or, at your request, with a special inspection certificate in conformity with national and international standards. RETSCH calibration certificates confirm a great number of precision measurements, thus ensuring an even higher statistical reliability for your quality control.
RETSCH test sieves are available in many sizes and varieties.SKU: n/a -
XRD McCrone Mills
XRD McCrone Mill
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. Consequently, the signals in the X-ray diffraction pattern are peak-shaped, with small half-widths, allowing for very good phase analysis.
The crystal lattice structure is largely preserved, with almost no defects, a prerequisite for meaningful X-ray diffraction patterns.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.

Zirconium Oxide Balls and Beads
Carbon Steel Balls, Glass Balls, Grinding Media, Stainless Steel Balls, Steel MediaZirconium Oxide Balls and Beads
Zirconium oxide balls and beads are a high-performance grinding media designed for demanding milling, dispersion, mixing, and size-reduction applications. Known for their excellent wear resistance, high density, and strong impact strength, zirconium oxide media provides efficient particle size reduction while helping to minimize contamination during processing. This makes it an excellent choice for applications requiring clean, consistent, and repeatable grinding results.
These balls and beads are commonly used in fine grinding, wet milling, bead milling, dispersion, homogenization, and particle size reduction of powders, slurries, pigments, ceramics, minerals, chemicals, coatings, inks, and specialty materials. Their high hardness and smooth surface finish help reduce media wear, improve milling efficiency, and extend service life compared to many traditional grinding media options.
Glen Mills carries zirconium oxide grinding media in a wide range of sizes to support laboratory, pilot-scale, and production applications. In addition to standard zirconium oxide balls and beads, we also offer additional specialized types suitable for pharmaceutical and high-purity applications where material compatibility, cleanliness, and contamination control are critical. These options are ideal for customers working with sensitive formulations, active ingredients, medical materials, and other applications requiring a higher level of process control.
Whether your application requires aggressive particle size reduction, gentle dispersion, or high-purity milling, zirconium oxide balls and beads provide a durable and reliable media solution for consistent performance across a wide range of industries.

Rotor Mills
ZM 300 Ultra Centrifugal Mill
Rotor mills are used for high-speed size reduction of soft to medium-hard as well as temperature-sensitive or fibrous materials.
The powerful Ultra Centrifugal Mill ZM 300 provides maximum grinding performance combined with ease of use. The variable speed from 6,000 to 23,000 rpm allows for gentle, neutral-to-analysis sample preparation in a very short time.
Thanks to an integrated temperature monitoring system, reproducibility is guaranteed even for long grinding processes or pulverization of large sample volumes.
The wide selection of rotors, ring sieves and cassettes makes the ZM 300 a true allrounder which meets the requirements of a great variety of size reduction tasks.
