ODM – Screw conveyors

Our screw conveyors provide transport your most varied and idiosyncratic materials, regardless of the angles – from horizontal to vertical.

Screw conveyors (also known as spiral conveyors) are well suited for powdered, granular, small-sized, semi-moist (british spelling w hyphen), and fibrous materials in all branches of industries. Constant improvements to our screw conveyors have have achieved a transport distances of more than 60 metres as well as a capacitance of 1,000 m³/h or more.

Screw conveyors are available in varying models and types. They can be used to discharge, dose, cool, mix, separate, compact, and load, as well as for their primary job of transporting. Depending on your requirements, screw conveyors can be implemented as dust-tight, air-tight or water-tight, thereby not only protecting your product from external influences, but also protecting the environment.

Should you only need to span a short distance of no more than 10 metres, screw conveyors without centre bearings are suitable and meet your requirements as a feeder, unloader, or intermediary conveyor.

DI MATTEO offers completely new units from scratch and spare parts for your existing equipment.
