Shaftless Screw Conveyors
SHAFTLESS SCREW CONVEYORS
Our screw conveyors of the shaftless type are designed to handle greater flow rates and are suitable for transporting heterogeneous or tangled materials that tend to cause machine blockages. This particular machine is designed to convey screenings, sands, granular substances and sludge.
The material is transported by a thick shaftless spiral that slides along an anti-friction and anti-wear coating at the bottom of a trough.
Contact us if you are interested in a shaftless screw for conveying screenings, sludge, sand, and much more. We can provide both standard and custom-built equipment to suit your needs.
SHAFTLESS SCREW CONVEYOR MOD. X-CONV
Shaftless screw conveyors consist of a power-driven, shaftless helicoid flight that rotates inside a trough to convey the material – fed by one or more hoppers – towards one or more discharge outlets, which can be fitted with a slide valve. The absence of a central shaft makes these machines suitable for transporting sticky materials such as sludge and screenings that tend to wrap around the screw spiral, causing a reduction in the flow rate over time.
OPERATING PRINCIPLE
La macchina può essere nella versione:
- “In tiro”: quando il motoriduttore, posizionato dopo la bocca di scarico, attira il materiale verso l’uscita
- “In spinta”: quando il materiale viene spinto dalla spirale verso lo scarico
L’azionamento può effettuarsi tramite collegamento diretto del motoriduttore alla spirale, oppure con un sistema di trasmissione motoriduttore – catena – albero flangiato della spirale. Il campo di lavoro della macchina è compreso tra 0° e 30° di inclinazione, con un rendimento di trasporto che scende all’aumentare dell’inclinazione.
