Vibrating cup mill with frequency
converter
Vibrating cup mill is particularly suited to the dry and wet grinding of brittle and very hard solids in a extremely short time to analytical fineness
Fritsch's new model, the Pulverisette 9, is said to be the world's only vibrating cup mill with frequency converter control This allows the vibration frequency of the motor to be varied to suit the load (grinding elements and grinding material) and the grinding is then carried out in a minimum of time

Vibrating cup still the best mill for some jobs
The vibrating cup mill is absolutely the best mill for fast grinding of hard and brittle materials to analytical fineness which has led to the latest Pulverisette 9 vibrating cup mill from Fritsch
The special field of the Pulverisette 9 vibrating cup mill is the dry and wet grinding of brittle and very hard solids in a extremely short time to analytical fineness.
Mining for processing coal, ores or minerals for physical or chemical analysis, metallurgy for grinding blast furnace slag or cast iron samples to determine additives needed.
Ceramic industry for grinding rock samples to produce raw powder to determine CaO3 and MgCO3 content or clinkers to study the consistency of the mineralogical structure.
Agriculture and ecology for preparing samples for chemical analysis of soils, sludges or vegetable matter infrared- and X-ray fluorescence for preparing samples in a short grinding time with minimal contamination through abrasion.
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.
Technical data: max feed particle size, 12 mm.
Sample quantity 50, 100 or 250ml.
Final fineness 10 - 20um. Request a free brochure from Fritsch ...
Rotational speed 1150rpm.
