Planetary ball mills meet all requirements for fast and reproducible grinding to analytical fineness. They are used for demanding tasks in the laboratory, from routine sample processing to colloidal grinding and advanced materials development.
With the new PM 300 Retsch has developed a powerful tool which offers high sample throughput combined with ease-of-use. Thanks to extremely high centrifugal forces which result in very high pulverization energy, planetary ball mills process soft, hard, brittle, and fibrous materials in dry or wet mode in a very short time. They cover a wide range of size reduction applications. A crucial advantage of planetary ball mills is their great versatility. This benchtop model with two grinding stations accepts grinding jar volumes up to 500 ml, which results in a maximum batch size of 2 x 220 ml sample material. The mill has a maximum speed of 800 rpm and the energy input of up to 64.4 times the acceleration of gravity. Taking into account that planetary ball mills are not as easy to handle as, for example, mixer mills, the PM 300 has been designed to offer user convenience and safety with several implemented safety features. With the new grinding jar line EasyFit, new options for the GrindControl system, and aeration lids, this mill opens up new possibilities in ball milling.
