Powder Conveying System particularly suitable for high capacity loads at low angular speed. It is made of a screw that rotates around its own axis, thereby exerting an axial thrust on the material contained in the conveyor tube.

The system is built of stainless steel 304 or 316; upon request it can be built of painted carbon steel.

This system reduces the number of manual adjustments that the traditional sealing systems require and also minimizes the annoying and hazardous powder leaks that reduce the duration of the bearings.

The intermediate support of the mechanical conveyor is made with a special self-lubricating material that is FDA-approved for contact with food; it has frontal seals, and a preloading device, made according to GIMAT design.

These are the advantages of the screw conveyor:

1. High flow rate;
2. Suitable for horizontal, inclined and even vertical travel (elevator);
3. Loading and unloading at any point of the line;
4. Self-support between the two bays;
5. Suitability for conveying products with high temperatures;
6. Stainless steel versions perfectly suitable for conveying chemicals, pharmaceuticals or food products.
7. Free of powder dispersion;
8. Durability;
9. Conveyed product can be cooled in cases of spiral conveyors made with outer jacket for containing coolant.
