Universal cutting mill with adjustable rotational speed of 300–3000 rpm – PULVERISETTE 19
With a rotational speed that can be adjusted in 100 rpm increments—ranging from 300 to 3000 rpm—you can precisely tailor the grinding process to each individual sample, covering a very broad spectrum of applications. The high-speed, universal PULVERISETTE 19 mill, featuring a torque of up to 30 Nm, grinds dry, soft, and medium-hard materials, as well as fibrous substances and plastics, delivering reliable, reproducible results. It accommodates a maximum feed size of 70 x 80 mm and offers a throughput of up to 60 l/h.
A key advantage: materials such as straw, films, and similar items can be fed into the mill in their full length, requiring no prior preparation. Furthermore, the PULVERISETTE 19 is ideally suited for testing in compliance with RoHS requirements. Its "Clean Design" construction ensures easy cleaning and provides robust protection against cross-contamination. Technical Data
