Concept and operation of the handling system, with radial screw and tunnel
||Silo wall (steel or concrete)
||Extraction screw motoreducer
support (steel or concrete)
The extraction screw (6), also called screw or auger is animated by two rotary movements:
- The first movement, is the rotation of the screw on his own axis, he is caused by the main motoreducer (3) located inside the tunnel. This motoreducer, drives the screw, through a conical gear located in the gearbox (7).
- The second movement, is the rotation of the screw at 360°,of the bottom of silo, he is caused by the sweeping motoreducer (4) located inside the tunnel. This motoreducer, drives through a pinion and a slewing ring the gearbox (7).
These two combined movements enable a homogenization of the product and its discharge through an opening in the center of the bottom slab of the silo to which is connected the recovery system.
