Screw conveyors are used when there is a need to move powdered products, particularly when it is necessary to move a specific quantity or to extract materials from hoppers, silos, etc.
The movement which enables the materials to be conveyed is created by means of a spiral attached to a shaft which is driven at one end by a motor unit, in a circuit that is usually tubular but that can have different structures depending on the needs of the machine itself.
It is a highly versatile system that offers a wide variety of standard solutions for the treatment of bulk materials. The screw feeders installed in the conveyors can be for extracting, measuring doses, or mixing depending on requirements or on the material to be conveyed. They are ideal for granules, powders and mixtures.
