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, soft 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.
