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.
