This laboratory mill allows you to adjust the cutting speed
The Universal Cutting Mill Pulverisette 19 (photo) is suitable for size-reduction of a wide range of different materials due to variable adjustment of the rotational speed of the rotor, various knife geometries, replaceable blades and practical sieve cassettes, as well as being easy to clean. The high-speed version comminutes up to 60 L/h of soft to medium-hard sample materials and fibrous materials at a torque of up to 30 Nm with reliable and reproducible results. The rotational speed can be adjusted from 300 to 3,000 rpm. The low-speed version has variable rotational-speed adjustment between 50 and 700 rpm and a torque of up to 67 Nm. The combination of low cutting rate and extreme cutting forces allow a very powerful comminution of hard, tough-elastic samples and small sample quantities. — Fritsch GmbH, Idar-Oberstein, Germany
