Dos Santos International, USA ( DSI ) is the world’s foremost authority in high angle conveyor applications and design of sandwich belt type high-angle conveyors. We offer the DSI Snake Sandwich conveyor, the most reliable and economical solution for your high-angle and vertical, high-tonnage requirements. Dos Santos International also offers discipline oriented engineering services in mechanical and structural engineering. Additionally we offer high-tech solutions through our expert consulting services. Our in-house proprietary software facilitates complete analysis of the most complicated conveying systems.
Our Background, Experience and Expertise
Dos Santos International is founded on our extensive worldwide experience in sales, engineering, and construction of bulk materials handling systems and equipment. This has included major contributions that have expanded the range of bulk handling and transport solutions. Most notably advances in sandwich belt high angle conveyors have led to their worldwide utilization. The company's expertise spans a wide range of materials handling systems and equipment including:
•High angle conveyors
•High powered, high capacity, high lift slope conveyors and long overland conveyors, utilizing the latest technology
•Plant conveyors, feeders, trippers, and related equipment
•Continuous open pit mining equipment and haulage systems utilizing bucket wheel excavators, beltwagons, face, connecting, and spoil conveyors, spoil side and/or cross-pit spreaders.
•Yard and dock handling systems and equipment, stationary and rail mounted mobile, including:
•Stackers and reclaimers
•Ship and barge loaders
•Continuous Barge Unloaders-CBU's of the pivoted arm type and of the cantilevered twin bucket ladder type
Origin
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 steep-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 & 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 Belt Conveyor represents the ultimate achievement of this aim.
Mr. Dos Santos’ research articles have been published in world-wide journals.
CONVEYORS
Long Overland, High Lift, and High Capacity Conveyors
We offer conventional conveying systems of simple or complex profile to high capacities and high lifts. Our overland conveyor projects have featured intermediate "booster" drives of the fixed tripper type as well as the belt on belt type. These have been effective in achieving great transport lengths with belts of only modest strength. "Booster" drives also allow us to control belt tension facilitating horizontal curves with minimal belt wander. Our conveyor systems will exploit the latest in equipment and technology to deliver optimal solutions.
Plant Conveyors
Our experience in integrated design, coordinating the best in equipment with the most efficient structural systems will be exploited to produce clean, attractive plant conveyor solutions.
Heavy Belt Feeders
We offer belt feeders from the very basic through the most rugged systems.
Conveyor Accessories:
•Take-up systems
- Fully Automatic
- Semi Automatic
•Transfers
- Discharge chutes
- Receiving skirts
•Belt trippers
- Fixed
- Travelling
Sandwich Belt Conveyors
A sandwich belt conveyor uses two conveyor belts, face-to-face, to gently but firmly contain the product being carried, hence making steep incline and even vertical-lift runs easily achievable. DSI Snake Sandwich Profiles are available in widely ranging profiles of C and S-Shape. In any case, a long bottom belt approach is possible to the sandwich entrance, and discharge may be on the high incline or may be after the extension of the carrying belt beyond the mouth of the sandwich. DSI Snake Sandwich conveyors offer the following advantages:
•Unlimited conveying capacity
•A system suitable for the most rugged mine applications, yet gentle on sensitive and friable materials.
•High availability and low operating and maintenance costs
•Smooth surfaced belts allow continuous belt cleaning by scrapers and plows. This also facilitates intermediate material discharge by belt plows, as appropriate, before and/or beyond the sandwiched part of the Snake profile.
•All conventional conveyor hardware insures economy and fast delivery of replacement parts.
Dos Santos-design sandwich belt conveyors have been proven in more than eighty successful conveyor systems installed by his previous employers throughout the world over the past eighteen years. Dos Santos’expertise will continue to advance the state of the art and assure our clients of the finest conveyor systems available today. The DSI Snake Sandwich is the most reliable and economical solution to your steep angle and vertical high-tonnage conveying requirements.
Rigging, Reeving and Hoisting
Dos Santos International offers special expertise in wire rope rigging, reeving and hoisting systems. This expertise has been gained through extensive experience with such systems related to remote take-up systems for conveyors, hoisting systems for stackers, loaders and other large yard and dock equipment. Rigging procedures and logistics have been worked in detail for special power plant maintenance projects.
Consulting and Engineering
Consulting and engineering Services are offered for the various industries including:
•Materials handling systems and equipment
•Power plant maintenance
•Steel mill equipment
Additionally, all industries may benefit from our discipline oriented engineering services. Such services are offered in mechanical and structural engineering.
Our services may be used for:
•Technical and economic studies and evaluations
•New systems
•Upgrade of existing systems
•Plant modifications and field assistance
ExConTec
DSI’s Expanded Conveyor Technology (ExConTec) enables the company to maintain its market position. The DSI ExConTec is a complete conveyor analysis program that can quickly analyze very complex systems during steady state running as well as transient starting and stopping conditions. It is more than an analysis tool, it reflects a philosophy. The comprehensive approach takes the conventional conveyor technology beyond the current perceived limits. It utilizes derived load equivalents, address and predicts the extra flexural and shear resistances along vertical and horizontal curves. The analysis models and software incorporate added features including ‘Engineer’s Discretionary Factors’, an allowance for incorporating the results of field testing or simply their client’s philosophy.
