Dos Santos International: History of Sandwich Belt High Angle Conveyor

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.

How to use this video

This footage from Dos Santos International is connected in PBV with Mechanical Conveying, Mechanical Conveying & Belt Conveyors, High-Angle Sandwich Belt Conveyors, Sandwich Belt High Angle Conveyor, Building Materials, Mining & Mineral, Recycling. It is most useful for examining the visible process sequence, equipment interfaces, access and material route. A video cannot confirm conditions that are outside the frame or were not measured.

Separate direct observation from commentary. Record what the equipment does, where material enters and leaves, which components move and how an operator interacts with the system. Treat capacity, accuracy, containment, energy, certification and service life as manufacturer claims unless the page provides attributable test evidence.

Engineering questions raised by the footage

• What feed distribution, rate and material trajectory enter the equipment?
• How are spillage, carryback, dust and displaced air controlled?
• Which belt, chute, vehicle or storage geometry constrains the layout?
• How can operators inspect, clean and isolate the equipment safely?

Use representative material data when answering these questions. Particle size distribution, bulk density, cohesion, moisture, abrasion, temperature and hazard properties can change the response of equipment that looks identical in a video.

PBV entity context

The relationships below connect the video with existing PBV topic pages. They support navigation and technical discovery. A relationship does not mean that the featured equipment is suitable for every application inside that topic.

Evidence boundary

The video and imported description support only the product, process and company statements they explicitly present. PBV does not infer an unshown specification or independent certification. Before selection, request the current data sheet, scope of supply, operating envelope, test method, maintenance requirements and exclusions for the offered configuration.

For a project review, compare the video with drawings and written process data. Confirm the upstream supply, downstream receiver, utilities, controls, cleaning method, safe isolation and response to credible faults. This turns visual discovery into a testable engineering inquiry.
