Vibrating Cup Mill Offers Extremely Fast Grinding!

Fritsch’s (Germany) Pulverisette 9 Vibrating Cup Mill is indispensable for all areas in which hard, brittle and fibrous materials must be ground down extremely quickly to attain analytical fineness. This is the world‘s first mill of its kind as it has a frequency transformer control developed by Fritsch. The principle advantage of Pulverisette 9 is perfect, loss-free grinding results in half the time!

Pulverisette 9 is 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 unsurpassed, 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 you 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 carried out by the grinding set’s horizontal circular oscillations on a vibrating plate. The grinding set, which consists of rings and puck, comminute the grinding sample with extremely high pressure, impact forces and friction. With 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 have developed a special motor with unique frequency transformer control for the Pulverisette 9. 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.
