Qualifications in Sandwich Belt High Angle Conveyors
Background – Origins of Sandwich Belt High Angle Conveyors, Innovations of J. A. Dos Santos

The sandwich belt concept was first introduced in the early 1950’s (1&2).  Then, known as “conveyor with cover belt”, it was used at the boom conveyor of a bucket wheel excavator, in a German lignite mine.  The “cover belt” was laid over and pressed onto the conveyed material so that the conveying angle could be increased, thus increasing the excavated bench height.  Other various cover belt concepts soon followed. These systems did not achieve a lasting success.  By end of the decade they were largely abandoned.

The first lasting success in sandwich-belt conveyors was achieved in the 1970’s with development of the Loop Belt for self unloading ships.  The Loop Belt, a C-shaped vertical elevating system, demonstrated that very high volumetric rates could be achieved using all conventional conveyor components and equipment including smooth surfaced rubber belts.  An inner belt is supported along a convex curve path of troughing idlers, while an outer belt wraps around the bulk material and the inner belt.  Hugging pressure on the bulk material is by radial pressure derived from the inherent tension of the outer belt and the convex curvature of the C-profile. Very wide belts, to 3048 mm (120”), are used to elevate various bulk materials continuously from the ships holds to the deck.  A discharge boom conveyor then transfers the bulk to shore.  Though used in many self-unloading ship applications, the Loop Belts did not develop further technically or commercially.  Limited to a C-shaped elevating profile they did not find many land based applications.

In 1979 the Bureau of Mines, United States Department of the Interior, funded a major study entitled “High Angle Conveyor Study”(1).  The purpose; to advance the state-of-the-art in high angle conveying; to develop high angle conveying systems that would reduce the haulage costs in open pit mines.  The study was awarded to a prominent U.S. engineering company.  Joseph A. Dos Santos- Project Engineer was assigned to the Study.

The Bureau of Mines Study was the beginning of the Dos Santos long involvement in and significant contributions to the development of high angle conveyor technology.

The study considered all high angle conveying methods.  It became clear to Dos Santos that the Sandwich-Belt concept offered the most promise for success.  Equally clear; it was the least understood.  His in-depth study and research produced the comprehensive theory of Sandwich-Belt High-Angle conveyors entirely rationalized in the conventional conveyor technology.  The prophecy: “A sandwich belt high angle conveyor system, utilizing all conventional conveyor components and equipment, subject to the conventional rules of their design, will result in the performance characteristics of a conventional conveyor system, that is, low cost, high reliability.”  The two volume “High Angle Conveyor Study” report, published in 1981, included the Dos Santos theory and various sandwich belt conveying methods by Dos Santos, pursuant to the theory.  Drawing from the success of the Loop Belt, Dos Santos Sandwich Belt systems included its best features but offered versatile profiles that could follow any high-angle path.

The Snake-Sandwich High-Angle Conveyor was cited as the preferred method and it was submitted for patent in 1981.  The Sandwich Belt High-Angle conveyor research and development was published more concisely in the 1982 landmark article “Evolution of Sandwich Belt High-Angle Conveyors” by Dos Santos and Frizzell(2).

    Dos Santos Sandwich Belt High-Angle Conveyors Installations Record 1982-1997

    Now recognized as a leading authority in the application and design of high-angle angle conveyors, J. A. Dos Santos was sought by a major U.S. manufacturer of conveyor systems and equipment.  He was offered the opportunity and challenge, to develop his innovations into commercial reality.  In 1982 Dos Santos accepted the challenge.   

    By mid 1983, in only 9 months, Dos Santos designed, built and started-up the first large scale prototype sandwich belt high-angle conveyor pursuant to his published theory.  The unit featured 1524 mm (60”) wide belts, 35 meters (115’) length and adjustable incline angle, from 30º to 60º.  It was powered by variable speed DC drives.  An immediate success, the prototype demonstrated high angle conveying of widely varying materials, from light weight wood chips to heavy, course ores, at rates to 2900 t/h (3200 STPH).  This Dos Santos invention, originally referred to as “Mechanically Pressed Sandwich Conveyor”,(1&2) features fully equalized pressing rolls to hug the conveyed material and develop its internal friction.  It was patented in the U.S. and abroad in 1986.

    Commercial success came slow initially, with only 7 units installed before 1990.  By 1997 however more than 80 units were in operation world wide.  These are located in the six civilized continents, in thirteen countries.  The installations vary widely in profile from compact C and S shapes, as small as 3.6 meters (12’) lift and 8.6 meters (28’) length, to long undulating profiles as high as 175 meters (574’) lift and 454 meters (1490’) length.  High conveying angles vary from less then 30º up to 90º (vertical).  The range and versatility of the Dos Santos designs is dramatized in Figure 1, where some of the various profiles are displayed at a common scale.  Materials handled vary widely in properties from light weight wood chips in pulp and paper applications to heavy course ores at copper and iron mines.  Belt widths from 500 mm (20”) to 2134 mm (84”) elevate the various materials at widely varying rates from .3 to 4250 t/h.  These sandwich belt high-angle units serve many industries including grain distribution, pulp and paper, municipal waste treatment and disposal, trans-shipment (including self-unloading ships and barges), power generation, construction and tunneling, and mining and processing.

    Numerous published articles by Dos Santos document the progress in sandwich-belt high-angle conveyors from 1982 to 1997(3-38).

      DSI Sandwich Belt High-Angle Conveyors Since 1997

      In 1997 Dos Santos International was founded on the experience and accomplishments of its name’s sake, Joseph A, Dos Santos.  Dos Santos International presented an opportunity to return to the roots of the sandwich belt conveyors.  The many sandwich belt installations by Dos Santos, from 1982 until 1997 fully proved the technology and are a great success. These are the realization of the “Mechanically Pressed Sandwich Conveyor”. At the DSI founding in 1997 we returned to the “Snake Sandwich” high angle conveyor, the preferred system.

      From 1997 to present (2024) Dos Santos International has continued the Sandwich Belt conveyor development adding some forty installations worldwide, both “Snake Sandwich” and “Mechanically Pressed Sandwich” units. 

       

      Dos Santos published articles (39-43) continue to document the progress.
