Dosing of Free-Flowing Bulk Materials
The drum feed device distributes the material from a pre-hopper evenly over the entire width of the mill. By regulating the speed of the drum, the amount of material the mill can be charged load-dependent. The drum feeder is additionally used for aspiration of the hammer mill as well as for continuous separation of foreign bodies of all kinds by means of two magnets and cross-flow sifting.
Take Advantage of These Benefits
Precise Feeding and Efficient Foreign Body Separation
- Load-dependent feeding of the hammer mill in combination with a controlled frequency converter
- Two extra strong permanent magnets for the separation of magnetic foreign bodies
- Cross-flow sifting for separation of non-magnetic foreign bodies and heavy parts
- Air flow adjustable to the product properties with vanes
- Pneumatically locked shut-off flap for shutting off the pre-hopper after the end of the batch
- Integrated empty indicator for controlling the shut-off flap
Reliable Operation and Long Service Life
- Robust welded steel construction for continuous industrial operation (24/7)
High Availability
- Avoidance of mill downtimes in case of damage by foreign bodies
- Easy access for cleaning and maintenance through flaps and a sliding door
- Magnets easy to clean
- Catch tray for cleaning the magnets, is hooked into the door opening
- Easy cleaning of the heavy parts catch tray
High Safety of Personnel and Plant
- Pressure shock resistant and flameproof design (0.4 bar)
- ATEX design according to zone 21 (II 2 D) inside and 22 (II 3 D) outside optionally possible
Upper Magnet can be pulled out for cleaning
Sliding door for good accessibility to the lower magnet and the heavy parts catch trap
Electronically controlled slide to adjust the product layer (option)
Aspiration air valve A-Vent for explosion isolation (option)
