Ultra-fine grinding down to the nanoscale—in no time at all
Thanks to revolutionary technology, the P-7 Premium planetary millrepresents a quantum leap in ultra-fine grinding: With 95 times Earth’s gravitational acceleration and relative bowl speeds of up to 2,200 rpm, the energy input is approximately 150% higher than that of conventional planetary mills. This enables the loss-free grinding of hard, medium-hard, and brittle materials down to final finenesses of 50 nm—with average grinding times of just 3 minutes to achieve analytical fineness.
Versatile Applications in Research and Development
The system is suitable for a wide range of demanding tasks: from conventional ultrafine grinding in geology, ceramics, and metallurgy, through mechanical alloying and colloid grinding, to applications in nanotechnology. Grinding can be performed dry, in suspension, or under an inert gas atmosphere. In addition, the mill enables the mixing and homogenization of emulsions as well as mechanical activation in materials research.
SelfLOCK Technology for Maximum Efficiency
The innovative SelfLOCK clamping system revolutionizes handling: The grinding beakers lock securely into place without additional clamping—eliminating the risk of operating errors. The grinding chamber opens and closes automatically, positioning the beaker holders conveniently for easy access. Beaker changes take just seconds. With two grinding stations and beakers with volumes of 20 mL, 45 mL, or 80 mL, up to 2 × 30 mL of usable volume can be processed simultaneously.
Intelligent Process Control and Validation
The ergonomic touchscreen provides intuitive navigation through the menu structure in 10 languages. Automatic RFID recognition of the grinding cups prevents invalid grinding settings and optimizes the rotational speed. An automatic parameter check before each grinding run guarantees precise reproducibility. The system locks during invalid operating conditions and automatically shuts down in case of imbalance, ensuring maximum process safety.
The MillControl software allows the mill to be automatically controlled and validated—target and actual rotational speeds and power consumption are continuously monitored and documented. The optional EasyGTM system expands the mill into an analytical measurement system: Special grinding jars equipped with transmitters measure gas pressure and temperature in real time during the grinding process.
A Variety of Materials for Contamination-Free Results
Six different grinding bowl materials—agate, sintered corundum, zirconia, hardened stainless steel, tungsten carbide, and silicon nitride—enable the targeted prevention of unwanted abrasion. Gas-flushing lids are available for grinding under an inert gas atmosphere and for mechanical alloying. For suspension grinding, a discharge device facilitates the rapid separation of grinding beads and the suspension.
The speed of the main disc is adjustable from 150 to 1,100 rpm, allowing for precise adaptation to different materials and desired final finenesses. This compact benchtop unit (40 x 58 x 36 cm, 44 kg) with 1,200 watts of power combines top performance with ease of use.
