History of Sandwich Belt High Angle Conveyors

In 1979, Joseph A. Dos Santos undertook a major study to develop a means of moving and elevating large quantities of bulk materials, including coarse products such as rocks, aggregate, coal etc. at the steepest possible inclines.
Dos Santos investigated and analyzed the many forces generated in this seemingly simple concept and created the formulas which guaranteed the successful design of such equipment. The DSI Sandwich Belt high angle conveyor represents the ultimate achievement of this aim.
