Unique grinding chamber geometry
The sample material is comminuted according to the cutting principle of scissors between the cutting edges of the rotor and the fixed knives in the grinding chamber until the desired final fineness is achieved.
Unique grinding chamber geometry: The grinding chamber is designed with minimal dead space and progressive cutting geometry between rotor and fixed knives. The sample material is continuously moved during comminution and cannot settle anywhere. In conjunctions with the special air flow, this is the basis for swift, blockage-free operation and fast cleaning without residue.
- Fast, reproducible and gentle pre-crushing – rotor speed 300-360 rpm
- High-torque geared motor (2.2 kW)
- Max. feed size: 120 x 85 mm
- Throughput quantity of up to 85 l/h
- Defined final fineness due to interchangeable sieve cassettes– 1 – 10 mm
- Collection vessel 3 litres or 10 litres
- Easy, fast and thorough cleaning of the grinding chamber and of all cutting tools
- Standard funnel for bulk solids 10 litres or protected funnel with pusher 3 litres
- Variety of rotors available to adapt the cutting performance to suit the sample
- Stable running and low wear due to patented double cone bearing of rotor
- Exceptionally long service life through use of replaceable and fixed knives
- Cutting rotor and sieve cassette can be removed and replaced without tools
- Externally adjustable cutting gap
- Housing and closing lid can be lifted to open completely
- Smooth, easy-to-clean interior grinding chamber walls
- Optimum airflow for particularly fast size reduction and secure protection against clogging
- Extensive accessories for simplifying your daily work
Unmatched easy cleaning!
While you are still tightening screws on other mills, is your FRITSCH Cutting Mill already clean. Because the entire grinding chamber can be opened easily in seconds and both the rotor and the sieve can be simply be removed with simple motions. The housing and closing lid can be lifted back completely, and the grinding chamber lid can be completely removed from its hinges.
The result: A completely open, empty grinding chamber with minimised dead space for simple quick cleaning and reliable protection against cross-contamination.
FRITSCH–Advantage: The rotor of the Cutting Mill is easy to remove without tools. For quick cleaning in between, the rotor can also be turned by hand while the mill is open.
Configure your Power Cutting Mill PULVERISETTE 25 exactly to your specific application
The Power Cutting Mill PULVERISETTE 25 is delivered without funnel, cutting tool set (consisting of rotors and fixed knives), sieve cassette, collection vessel and stand.
Various funnels, collection vessels, rotors with fixed knives, sieve cassettes and stand enable you to configure the Power Cutting Mill exactly for your application.

*The three-phase AC version„/3~“ is definitely preferable over a single-phase version „/1~“, since you obtain with the three-phase AC version more power, better effectiveness and a greater energy efficiency. Please note: the three-phase AC version „/3~“ must always be operated on a three-phase supply network.
