Pulverisettes: Laboratory Vibrating Cup Mill "pulverisette 9" 

For extremely rapid size reduction (rotational speed: up to 1150 rpm) of brittle and very hard samples dry or in suspension to analytical fineness. Typical fields of application: Mining, Metallurgy, Ceramic Industry, Agriculture and Ecology, Infrared and X-ray Fluorescence analysis. Method of operation: The "pulverisette 9" operates on the principle of a vibrating cup mill. The rotating flyweight makes the grinding set; clamped on a spring-loaded system, vibrate horizontally. As a result of the centrifugal force created, the tumbling movement accelerates the grinding elements (puck and rings), which make up the grinding set. The sample is ground by the impact and friction effect. The "pulverisette 9" is the only vibrating cup mill in the world with frequency transformer control. With this, the vibrating frequency of the load (grinding set and sample) can be adjusted so that grinding takes place in the shortest possible time.

Features of performance:

- Extremely rapid size reduction (1 to 3 min), high rotation up to 1150 rpm
- Speed varied by means of frequency converter and microprocessor
- High grinding energy for high load frequency
- wide choice of grinding materials and capacities
- Guided use of the grinding set with defined end position
- Anti-twist protection of the grinding set and automatic control of the grinding set clamp
- Loss-free grinding in hermetically sealed vessels
- Dry or wet grinding
- 2 year guarantee
