Planetary mills pulverise and mix soft, medium-hard to extremely hard, brittle and fibrous materials quickly without loss. Examples of applications include minerals, ores, chemicals, ceramics, soils, household and industrial waste and sample preparation for spectral analysis. These mills are suitable for long term trials and continuous use and are used for dry and wet grinding in all industry sectors, where a high degree of reproducibility, fineness, purity and speed is required. The excellent performance is achieved by the high centrifugal forces and very high pulverisation energy generated by the planetary mill design. The control system allows the operator to control speed, grinding time, direction reversal and interval times. The mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. Safety features include automatic safety self-test and a noise protected and ventilated chamber. A backup memory in the event of power failure ensures storage of remaining grinding time. Grinding sets are available in six different materials that allow sample preparation without contamination.

• Simultaneous processing of 1, 2 or 4 samples
• Extremely high fineness down to the submicron range
• Single button operation with graphics display and programmable start time
• Reproducible results due to digital parameter setting, 10 combinations of grinding parameters can be stored
• Automatic ventilation of grinding chamber for cooling grinding jars

Three benchtop models are available with either a single grinding station (PM 100, PM 100 CM) with jar capacity up to 500 ml, or with two smaller capacity grinding stations up to a total of 250 ml (2×125 ml -  PM 200). The PM 100 CM has a speed ratio of 1:-1, size reduction is effected by pressure and friction, rather than by impact, which means it is gentler on the material. The PM 400 is a robust compact floor model on castors with 4 grinding stations for grinding jars with a nominal volume of 12 to 500 ml. This allows for high sample throughput with excellent reproducibility, fineness and purity.
