For extremely fast comminution (speed: up to 1100 rpm, 1300 rpm at optimal speed) of hard-brittle, medium-hard laboratory samples, dry or in suspension, down to analysis fineness.

Mining, metallurgy, ceramics industry, agriculture and environmental, infrared and x-ray fluorescence analysis

The Vibrating Cup Mill operates according to the vibrating mill principle. The grinding set mounted on a spring supported system is caused to oscillate horizontally by a rotating flyweight. The whirling movement accelerates the grinding media (rings and core) situated in the grinding set via centrifugal force. The grinding material is comminuted through impact and friction forces.

The PULVERISETTE 9 is the world's only Vibrating Cup Mill with frequency transformer control. This allows the oscillating frequency to be optimally adapted to the load (grinding set and grinding material), performing the grinding in the shortest possible time.

• Extremely fast comminution (1-3 min) thanks to high speeds up to 1150 rpm
• Speed control with microprocessor and frequency converter
• High grinding energy with high loading frequency
• Different grinding set materials and sizes
• Guided insertion of the grinding set with defined end position
• Anti-twist protection of the grinding set and automatic monitoring of the grinding set clamping
• Lossless working in hermetically sealed vessels
• Dry or wet grinding
• 2-year warranty

Equipment

The standard equipment delivered with the Vibrating Cup Mill PULVERISETTE 9 does not include grinding sets. Grinding sets are offered in 5 different materials and different sizes and must be ordered as accessories:

• tempered steel grinding set for standard applications
• chromium-free steel grinding set for medium-hard, brittle samples
• hardmetal tungsten carbide grinding set for hard, abrasive materials
• agate grinding set for soft to medium-hard, brittle samples without metallic contamination
• zirconium oxide grinding set for medium-hard, brittle samples and for iron-free grinding
