Universal Cutting Mill - variable speed 300-3000 rpm PULVERISETTE 19
Variable 300 – 3000 rpm for fine comminution
Due to the variable rotational speed adjustment in increments of hundred between 300 and 3000 rpm you can fine tune the comminution process for each sample within a very wide range of applications. The high-speed Universal Cutting Mill PULVERISETTE 19 with a torque of up to 30 Nm comminutes dry to medium-hard sample materials and fibrous materials and plastics with reliable reproducible results with a maximum feed size of 70 x 80 mm and a throughput of up to 60 l/h. One special advantage: Straw, films and similar materials can be fed in up to their full length without additional preparation. And the PULVERISETTE 19 is also ideal for RoHS tests. Due to Clean Design of the PULVERISETTE 19, it is easy to clean and offers a safe 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.
Running stabilisation due to flywheel mass
The Universal Cutting Mill PULVERISETTE 19 is equipped with a flywheel mass to stabilize the drive torque. This ensures stable operation even for extreme short-term load, as well as an optimal comminution result.

The Universal Cutting Mill PULVERISETTE 19 with variable rotational speed 300-3000 rpm is available in the following voltages and versions:
|Order no.||Electrical details/ Torque|
| ||(three-phase motor with frequency converter and flywheel mass for stabilising the drive torque)|
|19.3060.00||for 380-460 V/3~, 50-60 Hz, 5000 watt, 30 Nm|
|19.3020.00||for 200-240 V/1~, 50-60 Hz, 2350 watt, 10 Nm|
|19.3030.00||for 100-120 V/1~, 50-60 Hz, 1725 watt, 8 Nm|
The PULVERISETTE 19 with voltage of “/3~”can only be operated on a three-phase supply network.
Despite the frequency converter, the three-phase version “/3~” is definitely preferable instead of a single-phase version “/1~”, because the three-phase version achieves a higher torque mass and pulling power.
The single-phase versions of the new Universal Cutting Mills PULVERISETTE 19 also have an especially maintenance-free three-phase motor with a frequency converter.
