Cutting Mill PULVERISETTE 15
The FRITSCH Cutting Mill PULVERISETTE 15 is ideal for the comminution of dry sample materials with soft to medium-hard consistency, for fibrous materials or cellulosic materials, as well as for sample preparation according to RoHS with a feed size of 70 x 70 mm and a throughput quantity of up to 50l/h. A cutting rotor speed of up to 3400 rpm ensures a high air throughput, fast processing and reproducible results.
The simple FRITSCH cleaning makes your work much easier.
In Cutting Mills, the sample is comminuted according to the cutting principle of scissors, increasingly fine between the knives of the rotor and fixed knives 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.

The PULVERISETTE 15 with voltage of “/3~” can only be operated on a three-phase supply network.
The three-phase version “/3~” is definitely preferable instead of a single-phase version “/1~”, because the three-phase version obtains more power, better effectiveness and greater energy efficiency.

ACCESSORIES FOR CHROMIUM-FREE COMMINUTION
When chromium-free size reduction is required for sample preparation according to RoHS – for example for verification of hexavalent chromium – or for XRF analysis. FRITSCH cutting tool sets of chromium-free tool steel and sieve cassettes made of chromium-free steel DC01 offer absolute assurance.
SIEVE INSERTS MADE OF STAINLESS STEEL 316L
Sieve inserts determine the final fineness of a sample. Sieve inserts with trapezoidal and square perforations are offered. Sieve inserts with trapezoidal perforations improve size reduction through extra shearing action. Sieve inserts with square perforations are used for the grinding of brittle materials and materials of medium fineness with a narrow grain band.
Sieve inserts are also available in further perforations.
