High angle muck removal for Paris project 28 Sep 2017

To enable 1,600 tonne of tunnel muck to be removed per hour from the Grand Paris Express tunnelling project, H&E Logistics of Bochum, Germany have commissioned two Dos Santos International (DSI) sandwich belt high angle conveyors. Each conveyor will elevate 800 tonne of muck per hour at a 90° angle.

The conveyors will be reused throughout the life of the project and in future projects. The Grand Paris Express, a €25.9 billion (US$29 billion) expansion of the century-old Paris Métro, is the most ambitious new subway project in the Western world.

Each conveyor uses two standard, smooth-surfaced conveyor belts, face-to-face, to gently but firmly contain the product being carried. This makes steep angles possible and offers a spillage free, environmentally sound operation as the material remains secured between the belts.

The conveyor is capable of higher speeds and greater capacity than other high angle conveying methods and the availability of wide belts and hardware make capacities greater than 10,000 tonne per hour achievable. 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, interchangeability of components and fast delivery of replacement parts.

DSI 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 has extensive worldwide experience in sales, engineering, and construction of bulk materials handling systems and equipment.
