Screw conveyors
Screw conveyors are used for handling dusty, granular and pasty products in dosing systems or simply for horizontal, vertical or inclined transport. The whole can be done using continuous spirals (with 1 or 2 principles) at a constant pitch, obtained from flat steel bars, welded on the screw shaft or through pressed steel sectors available with different pitches. It is also possible to handle wet or liquid products using special seals on the headers, a useful expedient if there is a need to sanitize the inside of the frame and the screw shaft of the conveyor without compromising the mechanical and electrical parts outside the frame itself. In special cases in which the product is extruded and a frame gets heat, it is possible to equip it with a liquid cooling circuit and external insulation. Depending on the type of product, hourly capacity and speed, our technical department will decide the most suitable section, the pitch and the materials to be used that are most suitable for the system that the customer must realize.
