New cutting mill from Retsch

News 06.03.2017

RETSCH have added a new model to their cutting mill family: the SM 400 XL is suitable for primary size reduction of very large sample pieces measuring up to 17 cm x 22 cm, but can also achieve the required final fineness in one step, depending on the application. The large surface of the bottom sieve (240 mm x 240 mm) permits processing of large sample volumes, resulting in a higher throughput than is possible with smaller cutting mills.

The high torque of the innovative 3 kW drive with flywheel mass allows for exceptionally effective primary size reduction of soft to medium-hard, tough-elastic, and fibrous samples as well as heterogeneous material mixes. The SM 400 XL also processes temperature-sensitive samples without too much heat built-up.

When operated with the optional cyclone-suction-combination the mill is also suitable for grinding light materials or small quantities.

The RETSCH cutting mill range includes three proven models for different requirements – SM 100 is the budget-priced basic model, SM 200 the universal standard model, and SM 300 is the high-performance model with RES technology. The new XL model now extends the application range to processing large sample pieces.


  • For feed sizes up to 170 mm x 220 mm
  • Powerful size reduction even of heterogeneous samples
  • Easy cleaning thanks to fold-back hopper and smooth surfaces
  • Suitable for processing heat-sensitive materials
  • Final fineness due to bottom sieves with aperture sizes from 0.5 mm to 20 mm
