Screw Elevators are the ideal solution for lifting and conveying bulk materials, powders, granules, and raw materials to elevated heights toward hoppers, silos, dosers, or processing machinery. The inclined geometry and the sizing of the internal flighting are engineered to guarantee a constant and efficient thrust, preventing clogging or product backflow.
Manufactured to the highest quality standards in AISI 304 stainless steel, AISI 316L stainless steel, or painted carbon steel, they provide maximum flexibility for both stationary and mobile systems. Depending on operational layout requirements, they can be equipped with support frames on wheels at a fixed height for easy movement within the plant, or with support frames featuring adjustable feet or brackets for floor anchoring.
Screw: single or double

AVAILABLE IN ASSEMBLY KITS
Our screw conveyors are available in "assembly kits" to reduce dimensions and limit transport costs. In this way, it is possible to store the kit of a conveyor over 30 m long inside a 20 ft container (approx. 6 m). All components are pre-assembled, except for the welding of the trough casing sheets and the final assembly of the screw and motorization. Drawings, 3D models (SolidWorks), and all notes necessary for assembly are also provided.
Customization and Tailor-Made Accessories
Our engineering capability allows us to customize every machine based on specific capacity, dimension, and footprint requirements. Key integrable accessories include:
Drainage Systems: drainage grid with removable liquid/water collection tray and DN65F full discharge outlet.
Protections and Safety: trough covers (fully inspectable for cleaning and maintenance operations).
Automation and Control: integrated, custom-wired electrical control panel.
