Variable 50–700 rpm for powerful comminution for larger amounts
The PULVERISETTE 19 large is our powerful low-speed Universal Cutting Mill for fast reproducible comminution of hard, tough-elastic and temperature sensitive materials and plastics with a maximum feed size of 120 x 85 mm and a throughput of up to 85 l/h with a low rotational speed of 50-700 rpm and a maintenance-free 2.8 kW three-phase motor with frequency converter.
Due to the variable rotational speed adjustment in increments of ten between 50 and 700 rpm and a torque of up to 67 Nm enables the PULVERISETTE 19 large due to the combination of low cutting rate and extreme cutting forces a very powerful comminution.
At the same time, it is the ideal solution for all cases where e.g. thermal damage, the loss of highly volatile substances, or an excessively high fine share need to be avoided. And the PULVERISETTE 19 large is also ideal for RoHS tests. Due to Clean Design the PULVERISETTE 19 is quickly and simply cleaned and offers a reliable protection against cross-contamination.
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.
