Universal cutting mill with an adjustable rotational speed of 50–700 rpm – PULVERISETTE 19 large
The PULVERISETTE 19 large is our powerful, low-speed universal mill designed for grinding hard, elastic, and heat-sensitive materials, as well as plastics. It accommodates a maximum feed size of 120 x 85 mm and offers a throughput of up to 85 l/h. The unit operates at a low rotational speed of 50–700 rpm and is powered by a 2.8 kW, maintenance-free three-phase motor equipped with a frequency converter.
With a rotational speed that can be adjusted in 10 rpm increments—ranging from 50 to 700 rpm—and a torque of up to 67 Nm, the PULVERISETTE 19 delivers highly effective grinding by combining a low cutting speed with extreme cutting forces.
At the same time, it is the ideal solution for applications where it is necessary to prevent issues such as thermal damage, the loss of highly volatile substances, or an excessive proportion of fine particles. The large-capacity container of the PULVERISETTE 19 is also perfectly suited for conducting tests in compliance with RoHS requirements. Thanks to its "Clean Design," the PULVERISETTE 19 can be cleaned quickly and easily, ensuring reliable protection against cross-contamination. Technical Data
