One or two slot adjustment drive units are placed on the outside of the discharge cone.
The unit consists of a geared motor mounted on the discharge cone, which through a gear drives the flap plate by engaging an arced gear rack connected to the flap plate.
The movement of the flap plate is adjusted from the control room/cabinet and the desired division ratio is achieved quickly.
A limit switch in each end position will stop the movement and inform whether the damper is fully closed or fully open.
