According to FRITSCH, its new universal cutting mills are ideal for the size reduction of a wide range of materials. The units reportedly offer variable adjustment of the rotor’s rotational speed, various knife geometries, replaceable blades, practical sieve cassettes and ease of cleaning. The PULVERISETTE 19 high-speed universal cutting mill comminutes up to 60 l/h of soft to medium-hard sample materials and fibrous materials at a torque of up to 30 Nm. The variable rotational speed adjustment in increments of 10 between 300 and 3,000 rpm reportedly enables the comminution process to be fine-tuned for each sample in a wide range of applications.

The low-speed PULVERISETTE 19 provides variable rotational speed adjustment between 50-700 rpm and a torque of up to 67 Nm. The unit’s combination of low cutting rate and extreme cutting reportedly forces a powerful comminution of hard, tough-elastic samples and small sample quantities. At the same time, according to FRITSCH, it is the ideal solution for applications where thermal damage, the loss of highly volatile substances, or an excessively high fine share need to be avoided.

FRITSCH universal cutting mills can be combined with a FRITSCH cyclone separator for sample exhaustion. The strong airflow reportedly ensures simple feeding, increases throughput, reduces the thermal load of the samples and enables the use of finer sieve cassettes to achieve a higher final fineness.

For residue-free cleaning, all grinding parts of these cutting mills can reportedly be removed within seconds without tools. The result is a completely open, empty grinding chamber with minimized dead space and smooth interior walls for quick and easy cleaning and reliable protection against cross-contamination.
