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.

The Jaw Crusher BB 500 is used for rapid, effective, crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Its variety of materials offered, including heavy-metal free steel, and its efficiency and safety makes the BB 500 ideal for sample preparation in laboratories and industrial plants.
For small amounts of sample the BB 500 is used batch-wise; for larger amounts it can be operated continuously. Control of the gap width and zero-point adjustment allow for reproducible results.
The BB 500 with its steep crushing chamber and powerful drive provides for very effective crushing kinematics.
The Mortar Grinder RM 200 can mix and homogenize powders, suspension and pastes, even for samples with high viscosity. The RM 200 is suitable for the proper and reproducible sample preparation to analytical fineness.
The sample grinder substitutes cumbersome hand mortars by a high performance drive with electronic control. The grinding set can be cooled and heated and is very easy to clean. Grinding sets of various material qualities are available which can be exchanged easily for optimum adaptation to various grinding tasks.
The knife mill GRINDOMIX GM 300 is the ideal instrument for grinding and homogenizing foods and feeds. It allows to process sample volumes up to 0.7 liters quickly and reproducibly.
With four sharp, robust blades and a powerful 1000 W motor, it is ideal for homogenizing substances with a high water, oil or fat content as well as for grinding dry, soft and medium-hard products. A wide selection of lids and containers allows for adaptation of the mill to individual application requirements. The GRINDOMIX GM 300 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.
The Ultra Centrifugal Mill ZM 200 is a high speed rotor mill with unmatched performance. It is used for the rapid size reduction of soft to medium-hard and fibrous materials.
Because of the efficient size reduction technique the ZM 200 ensures the gentle preparation of analytical samples in a very short time. The comprehensive range of accessories including a large variety of ring sieves and rotors as well as collection systems makes the Ultra Centrifugal Mill a versatile instrument that can be easily adapted to varying applications. The optional Vibratory Feeder is load-controlled via an interface and ensures a uniform grind at maximum output rate. When using a cyclone, the sample material is additionally cooled by the air stream and more rapidly discharged from the grinding chamber via the cassette pan with outlet. This effect can be increased by connecting a vacuum cleaner.
With thousands of installations, the ZM 200 has become a standard for food and feeds, for the chemical industry as well as for agricultural testing.
