Screw Conveyors
|
In several industrial sectors, the need for conveying fine-grained or small-sized bulk material with sealed machines, generally over small distances, can be satisfied by the various types of screw conveyors supplied by VAID. A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others:
- CO - Horizontal screw conveyors: generally used for powdered materials or small-sized material to be conveyed horizontally or with slight inclination (which may however reach 450 or more).
- CV - Vertical screw conveyors: used for vertically lifting fine-grained material (also known as screw elevators).
