xviii Vibrating Cup Mill Offers Extremely Fast Grinding
The Fritsch Vibrating Cup Mill PULVERISETTE 9 is indispensable for all areas in which hard, brittle and fibrous materials must be ground extremely quick down to analytical fineness. As the world‘s first mill of its kind, it has a frequency transformer control developed by Fritsch.
Ideal for fast sample preparation, such as in the areas of spectroscopy preparation, ore and geology laboratories, mining and metallurgy, ceramics industry, agriculture and environmental science, infrared and x-ray fluorescence analysis.
No similar mill offers a more convenient operation. The working position is ergonomically optimised, the ease of cleaning is without match, the grinding set is placed on a practical carriage, allowing it to be easily moved to the final position and rapidly fastened in seconds with a quick clamping system – which is back-friendly and saves energy and time.
A special detector automatically detects when users use an agate or zirconium oxide grinding set for metal-free grinding and reduces the rotational speed independently.
A symmetrical eccentric developed by Fritsch ensures fast and safe clamping of the grinding set, which is also automatically monitored. The defined final position and an integrated anti- twist protection provide additional safety.
In the Vibrating Cup Mill, the grinding is performed by horizontal circular oscillations of the grinding set on a vibrating plate. The grinding set consisting of rings and puck comminute the grinding sample with extremely high pressure, impact forces and friction. In this form of grinding, the transmission of forces onto the grinding sample is much more important than the pure motor power. For this reason, Fritsch developed a special motor with frequency transformer control for the PULVERISETTE 9 as the first provider worldwide. This makes it possible to adapt the motor speed to the respective load on the vibrating plate, ensuring optimal comminution.
Alternatively, fixed speeds can also be selected. Naturally, the grinding parameters can also be configured for absolute reproducibility.
