A Planetary Mill with infinitely variable grinding conditions and therefore the ideal mill for mechanical activation and alloying. The main applications are in the field of materials research and, of course, wherever a powerful, innovative planetary mill is required.
Typical fields of application
The vario-planetary mill is capable of emulating ball mills of conventional design, precisely simulating the types of stress entailed and thus reproducing or optimising grinding processes.
Method of operation
But with the vario-planetary mill the rotational speeds of grinding bowls and supporting disc can be adjusted completely independently of each other in contrast to standard planetary mills. By changing the transmission ratio it is therefore possible for the first time to carry out mechanical activation as well as mechanical alloying.
Features of performance
- free selctable, controlled rotation speed for grinding bowls and supporting disc
- Programming of the grinding parameters by PC software as desired
- RS232 interface for programming and to transfer grinding parameters to the PC
- Real-time display of the speeds to monitor the grinding process
- Reversing option to improve the grinding results
- Emulation of various ball mills
- Variably adjustable pressure on sample (friction and/or impact)
- Simultaneous grinding in up to 4 small or 2 large grinding bowls
- Quick, secure fastening of the grinding bowls "safe lock"
Equipment
The Vario-Planetary Mill pulverisette 4 is equipped with 2 bowl fasteners and a "safe lock" clamping system. This mill is delivered without grinding bowls and balls, which are available in 9 different materials and must be ordered as accessories.
