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
