Variable 50–700 rpm for powerful comminution
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 due to the combination of low cutting rate and extreme cutting forces a very powerful comminution. The low-speed PULVERISETTE 19 comminutes hard, tough-elastic samples with a maximum feed size of 70 x 80 mm and a throughput of 60 l/h. 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. 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.
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.
