FRITSCH PULVERISETTE 25 / PULVERISETTE 19 Cutting Mill Combination in Mills

FRITSCH PULVERISETTE 25 / PULVERISETTE 19 Cutting Mill Combination
Cutting mills comminute the sample by cutting and shearing forces. They are ideal for comminution of soft to medium-hard, fibrous and tough materials, plastics and heterogeneous mixtures. The FRITSCH-Plus: unbeatable quick and easy cleaning - all grinding parts can be removed in a few seconds without tools.


Cutting Mill Combination PULVERISETTE 25 / PULVERISETTE 19: Suitable for comminution of extremely heterogeneous samples. Max. feed size: 120 x 85 mm

Areas of application
The Cutting Mill Combination can comminute samples of up to 2 litres in one step from 30 mm down to a final fineness of < 500 µm. A representative portion for analysis is available within 5 minutes. The combination is used, among other applications, for the preparation of heterogeneous substances for analysis according to the Technical Instruction on Municipal Waste Management (TOC) or for determination of calorific value and chlorine content. Even completely heterogeneous samples such as household waste, construction waste, German recycling system bales or light shredder fractions from automobile recycling can be prepared.

Method of operation
The Cutting Mill Combination consists of the Power Cutting Mill PULVERISETTE 25 and the Universal Cutting Mill PULVERISETTE 19. The entire sample is pre-ground in the PULVERISETTE 25. The pre-ground sample falls through a funnel into the sample divider, which by default divides the sample in a ratio of 1 : 13. The dividing ratio is variable.
