| Description | Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of the Planetary Ball Mills result in very high pulverization energy and therefore short grinding times.
The PM 100 CM is a convenient benchtop model with 1 grinding station. It operates in centrifugal mode mode, which leads to a more gentle size reduction process with less abrasion.
Features - Powerful and quick grinding down to nano range
- Perfect stability on lab bench thanks to FFCS technology
- Innovative counter weight and imbalance sensor for unsupervised operation
- Gentle grinding in centrifugal mode
- Comfortable parameter setting via display and ergonomic 1-button operation
- Automatic grinding chamber ventilation
- 10 SOPs can be stored
- Programmable starting time
- Power failure backup ensures storage of remaining grinding time
- Reproducible results due to energy and speed control
- Suitable for long-term trials and continuous use
- 2 different grinding modes (dry and wet)
- Optional pressure and temperature measuring system PM GrindControl
- Measurement of energy input
- Wide range of materials for contamination free grinding
- Safety Slider for safe operation

- High final fineness
- Exchangeable grinding and sieve inserts
- Grinding chamber, feed hopper and material inlet and outlet of stainless steel
- Optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
- Optional distance rotor to reduce frictional heat
- Removable hopper for easy cleaning
- Motor brake
- Defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm
... Read More | 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 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 pre-requisite for meaningful X-ray diffraction results.
Features: - Crystal lattice preserved during grinding operation
- Very narrow and reproducible particle size distribution
- Minimal cross contamination
- Compact, bench-top sized model
- Suitable for dry and wet grinding
