Powerful pre-crushing

The FRITSCH PULVERISETTE 25 is our heavy duty Power Cutting Mill for fast, reproducible pre-crushing of dry, soft to medium-hard or fibrous materials and plastic with a feed size of 120 x 85 mm and a throughput quantity of up to 85 l/h with a low rotor speed of 300/360 rpm with a high-torque 2.6-kW geared motor.


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.
