Your powerful solution for tough tasks
- Future-proof thanks to energy-efficient discharge
- Highly effective forced discharge from bunkers
- More powerful and efficient thanks to hydraulics
Systematic and well rounded
AGRICHEMA’s ROTOSTAR® rotary screws reliably empty flat-bottomed bunkers with that have a central outlet.
The ROTOSTAR® rotary screw works with a circular motion, thus reliably discharging the entire bunker cross section.

AGRICHEMA’s ROTOSTAR® rotary screws
work completely hydraulically. A hydraulic aggregate supplies the required quantity of oil and the pressure.
In normal operation, the screw (1)
is driven by the hydraulic motor (2)
and the bulk solids are driven towards the centre.
The feed drive (3), which is connected in series with the hydraulic motor, provides the screw’s rotational movement.
In overload operation, no screw feed is performed.
Parallel to the hydraulic motor, an overflow valve with downstream hydraulic cylinder (4) is activated.
This engages with the rotary screw via a ratchet that has ten times higher torque.
This patented system reliably releases the screw when starting up or when it faces strongly solidified bulk solids.
We would be pleased to help you select the product that best meets your needs.

High level of operational safety thanks to the patented release system.
One hydraulic aggregate can drive multiple rotary screws.
No counter-bearing required for screws in silos of up to 20 m diameter.
Overflow valves secure all system components.
A system for the future.
