Prior to his founding of DSI, J.A. Dos Santos was responsible for a number of cement plant Sandwich Belt high angle conveyor installations. The first example of a Sandwich high angle conveyor delivering raw products for cement manufacture was in an underground gypsum mine. The vertical system continuously elevated gypsum rock.

WhatsApp: +86 18221755073The path required a down-hill high angle conveyor; thus, Dos Santos International was approached about their DSI Sandwich Belt High Angle Conveyor. Being the best solution, DSI was awarded the contract in March 2009 for a downhill high-angle conveying system which they dubbed the DSI G.P.S. (Gently Pressed Sandwich) High Angle Conveyor.
WhatsApp: +86 18221755073The studies into the belt stress state in the linear branch of the high-angle conveyor shows that the belt stress state is complex and depends on the belt properties, tension and hold-down. The down-hold is evaluated for the high-angle pressure belt conveyors with a capacity more than 3000 t/h and angles more than 30°.
