Roller mills for smaller capacities

  • One, two and three-stage grinder
  • Central drive
  • Simple roller change
  • Dust-tight design for the chemical and pharmaceutical industry

The grinders of the series WMS have been designed especially for smaller capacities. The grinder WMS-C allows crushing with a narrow particle size distribution. The narrow particle size spectrum is achieved by means of a continuous compressive shear action between two corrugated rollers with a defined roller gap.


  • One, two or three staged, phased grinding
  • Central drive for all grinding sections
  • Central drive via twin V-belt
  • Uniform particle size distribution with a low dust content
  • Dust-tight design
  • Sound insulation of the complete grinder
  • Precise grinding gap adjustment

Execution and options

  • All product-contacting parts are made of stainless steel, material no. 1.4571
  • Electrical switch cabinet
  • High-alloy rollers (Cr)
  • Cooling rollers
  • Equipotential bonding against static charging
  • Aspiration connection
  • Connection for inert gas supply
  • Magnetic separator above the feeder
