Robust construction. Long service life.
Gruber HM Series Fan Hammer Mills
The proven standard blower hammer mill HM: Robust and inexpensive.
The Gruber Blower Hammer Mill HM is suitable for use with short to medium intake lengths. A special suction head with a foreign body separator prevents the mill from clogging. The hammers of this Gruber grist mill can be turned four times, thus achieving low operating costs. An optional engine load-dependent flow control and automatic switch-off make the shot process easier.
The following types are available:
- Hammer mill HM 1000 with 5.5 or 7.5 kW
- Hammer mill HM 2000 with 11 or 15 kW
- Hammer mill HM 2000 with power take-off 120 kW (1000 rpm)
- Hammer mill with fan 2 flg. or 4 flg.
- Self-priming – suitable for short to medium suction and delivery paths
- hardened hammers – 4 x turnable
- Drive with electric motor 3000 rpm.
Additional equipment on request:
- Fully automatic mill shut-off
- Fully automatic volume control
Intake head with fully automatic volume control
Hammer mill equipped with magnetic field motor, which controls the grain intake fully automatically depending on the load on the mill motor. The mill is fed so precisely that it is almost always fully utilised, but not overloaded. The magnetic field motor works without electronics, so an almost unlimited service life can be expected. The magnetic field motor can also be used without automatic switch-off and can be mounted on all types of intake. The non-plus-ultra in mill construction.
Fully automatic switch-off
Mode of operation: As soon as the grain is ground, the mill runs empty, the motor reaches no-load current. At this moment, the automatic switch-off function starts. After the set run-on time has elapsed, the mill switches off automatically. No toggle switch – therefore clog-proof.
- No clogging thanks to special suction head with foreign body separator
- Hammers 4 x turnable – therefore longest service life
- Robust quality
- Largely maintenance-free construction
