Dos Santos International to Supply High Angle Conveyors to Paris Tunneling Project

The DSI Sandwich high angle conveyor will elevate 800 t/h of tunnel muck at a 90 degree angle.

Dos Santos International is pleased to announce the award of a contract to provide two DSI GPS (Gently Pressed Sandwich) high angle conveyors with H+E Logistics for the Paris Tunneling Project.  The DSI GPS will elevate 800 t/h of tunnel muck at a 90° angle.  The DSI Sandwich conveyors will be reused throughout the life of the project.

The extension of the Grand Paris Express is the most ambitious new subway project in the Western world.  The extension is a $25 billion expansion of the century-old Paris Métro.

DSI Sandwich belt high angle conveyors take on many forms and offer many advantages.  Each DSI Sandwich Conveyor uses two standard, smooth-surfaced conveyor belts, face-to-face, to gently but firmly contain the product being carried.  This not only makes steep angles possible;   it also offers a spillage free, environmentally sound operation because the material remains secured between the belts.

The DSI Sandwich high angle conveyor will transport 800 t/h of tunnel much at a 90 degree angle.







A DSI sandwich conveyor is capable of higher conveying speeds and greater capacity than other high angle conveying methods.  The availability of wide belts and hardware makes capacities greater than 10,000 t/h easily achieved with a DSI Sandwich conveyor.  High angles of 90° are typical, and lifts of 300m are easily accomplished.

The use of all conventional conveyor parts ensures high availability and low maintenance costs, as well as interchangeability of components and fast delivery of replacement parts.

Dos Santos International is the world’s foremost authority on sandwich belt high angle conveyors, founded and led by the inventor of the system, Joseph Dos Santos.  DSI was founded on its extensive worldwide experience in sales, engineering, and construction of bulk materials handling systems and equipment. This has included major contributions that have expanded the range of bulk handling and transport solutions. Most notably advances in sandwich belt high angle conveyors have led to their worldwide utilization. The expertise of DSI spans a wide range of materials handling systems and equipment including high angle conveyors, high powered, high capacity, high lift slope conveyors and long overland conveyors utilizing the very latest technology.
