The Planetary Ball Mill PM 100 is an advanced benchtop system used for grinding up to 220 mL of sample material per batch. The system has a single grinding station and an easy-to-use counterweight, which compensates for masses up to 8 kg.
The Planetary Ball Mills have high centrifugal forces and generate very high pulverization energy, thus reducing the time taken for grinding.
The system can be found in all industries where quality control processes require improved speed, reproducibility, purity, and fineness.
The mill can be deployed in research activities, such as in mechanochemistry (co-crystal screening, mechanical alloying, mechano-synthesis, and mechanocatalysis) as well as everyday tasks such as mixing and homogenizing hard, fibrous, brittle, or soft materials.
