For a wide range of common applications   
   
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.   
   
WORKING PRINCIPLE   
   
Unique grinding chamber geometry   
   
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.
