AGRICHEMA’s ROTOSTAR® silo discharge 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 silo discharge 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.
