SAMPLE PREPARATION FOR ANALYSIS
High performance in minimum space
The Planetary Mono Mill PULVERISETTE 6 classic line is a high-performance Planetary Ball Mill with a single grinding bowl mount and practical, easily adjustable imbalance compensation. Your advantage: Particularly easy use and high-energy effect of up to 650 rpm. This ensures a constantly high grinding performance with extremely low space requirements for loss-free grinding results for the comminution of hard, medium-hard, brittle and moist materials, dry in suspension or in inert gas.
At same time, the PULVERISETTE 6 classic line is ideally suited for mechanical alloying or for mixing and perfect homogenising of emulsions and pastes.

Comminution according to the Planetary Principle
The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. To achieve this, the grinding bowl, containing the material to be ground and grinding balls, rotates around its own axis on a main disk whilst rotating rapidly in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding bowl. The grinding balls then cross the bowl at high speed and further grind the sample material by impact against the opposite bowl wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process.
Due to the enormous rotational speed of the main disk – up to 650 rpm – achieves the PULVERISETTE 6 classic line a centrifugal acceleration of up to 29 g.
Reproducible grinding results and absolutely safe grinding bowl clamping
Especially convenient for exact, reproducibility and grinding of smallest sample amounts is the electronic timer: adjustable to the second and a programmable reversing feature. The Safe-Lock System, which is delivered with a torque wrench, enables simple and safe clamping of the grinding bowls – absolutely risk-free.
GTM – Gas Pressure and Temperature Measuring System
The Planetary Mono Mill PULVERISETTE 6 classic line can be combined with the GTM-System for measuring of the gas pressure and temperature during grinding. This turns your mill into an analytical measuring system.
Configure your Planetary Mono Mill PULVERISETTE 6 classic line exactly to your specific application
The Planetary Mono Mill PULVERISETTE 6 classic line with 1 working station operates with 1 respectively 2 grinding bowls of sizes 80, 250, 500 ml, which turn with a transmission ratio 1 : -1,82 relative to the main disk. To achieve best grinding results and for direct prevention of contamination of the samples due to undesired abrasion, grinding bowls and grinding balls are available in 6 different materials.
For grinding in inert gas, for mechanical activation and alloying are gassing lids recommended.
