For the grinding of solids the use of a cyclone can be beneficial, depending on the material properties. The rotation of the mill’s rotor or a connected vacuum cleaner produces a rotating air flow inside the cyclone, thus optimizing the air throughput. As a result, sample and grinding tools are cooled and material discharge is improved. These effects are particularly beneficial when grinding temperature-sensitive materials. Further advantages are the complete recovery of the sample material as well as the possibility to process larger sample volumes. The laboratory equipment specialist Retsch from Haan near Düsseldorf offers various mills which can be equipped with a cyclone.
