This comprehensive video shows the ingenuity and expertise of Dos Santos International and their world renowned Sandwich belt high angle conveyor. Dos Santos International has been providing a proven, reliable and economically sound high angle conveying system for over 20 years.

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. It was also his intent to use only existing and generally available hardware in order to achieve the most economically feasible and easily maintained high angle conveyor design.

Mr. Dos Santos conceived, researched and developed his sandwich belt design, with the help of a grant from the U.S. Bureau of Mines, while he was employed by a major American manufacturer of materials handling equipment. While such concepts had been tried over the years with mixed results, 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 Snake Sandwich Conveyor represents the ultimate achievement of this aim.
