Archimedys™ for a sewage sludge treatment plant in Chile


Archimedys™, our modular auger solution, was chosen by one of our customers in Chile for its sewage sludge treatment plant.

Archimedys™ eliminates all constraints encountered by our customer.

How do you maintain an auger, immersed at 6 meters depth? How to avoid the corrosion of a screw immersed in water and mud? How to bring up difficult products in an inclined conveyor without intermediate bearings to avoid blockages? Simply by doing nothing! Our customer in Chile needed to install an auger at the bottom of the hopper, which was submerged and almost inaccessible. It was necessary for him to find a maintenance-free solution without intermediate bearings and insensitive to corrosion. Archimedys™, due to its modular concept, met all its requirements.

It’s difficult to find a supplier for auger and transport them to Chile. Archimedys ™ solves all the logistics and manufacturing problems since the screw is assembled at the very foot of the installation.

Archimedys™ – 9 meters long.

Screw Archimedys™ of 9 meters long As you can see on pictures, an 9 meter long screw (DN230) can be carried by hand very easily in the workshop.

Archimedys™, the ideal solution for conveyor refurbishment

Main advantages of this new technology are the need for quick handling by maintenance personnel, quick installation, and recovery of existing elements. Equipped with a simple and compact design, the Archimedys™ auger is lighter than a steel auger. This greatly facilitates its installation. The auger is simply constructed, without any welding, by assembling standard modules directly on site. Moreover, if damaged, modules are replaced in case of accident. They are then put back on the axle without having to replace the whole auger.

The techno-polymer used for its manufacture has a high resistance to corrosion. Its abrasion resistance is often three times higher than steel.

Easier maintenance

The Archimedys™ advantages for maintenance are innumerable. Only the damaged modules are replaced and put back on the axle, not the whole auger. Maintenance operations are very simple and quick. Maintenance costs and times are reduced, as are operating losses due to downtime.

Archimedys™, a technological revolution!

The modular auger Archimedys™ advantages are such that more and more industrialists decide to abandon steel in favour of Archimedys™.

Modular auger Archimedys™ received the “Prix de l’innovation industrielle” in 2011
