Type MT

The mill type MT is designed for grinding of dry and free flowing products, and also for high fibers.

The MT series comprises of four sizes and a range between 90 and 450 kW for the drive.

Technical Details

  • Symmetric housing, allows operation in both directions
  • Swiveling inlet flap with proximity switches to change sense of rotation
  • Enforced impact plates at both sides of the mill inlet, exchangeable
  • Foreign body trap inside the grinding chamber, easy to clean
  • Special rotor design, run down time less than 6 minutes without brake
  • Four segment sieve with chain tensioning, exchange single elements when worn
  • Change screens while machine has stopped
  • Automatic door locking system with stand still monitor
