Dos Santos International
 Adds Six New Units in Second Half of 2005
   
Dos Santos International has had great success with its Snake Sandwich Conveyors in 2005.  The past six months alone have seen as many new units on order.  The units are spread out over three orders from repeat customers.

 

Snap Lake Snake 1
Snap Lake Snake 2

The first order, placed in July 2005, is for two units to be installed at the Snap Lake diamond mine in Northwest Territories, Canada.  These units will ultimately elevate kimberlite at rates of 500 t/h and 550 t/h up a 49.5 degree incline to 18.3m of lift.  These units are currently in fabrication and will be delivered to Edmonton, from where they will take ice roads to their final destination.  See complete specifications for these units by clicking here or on their pictures.
 

Victor Snake 1


Victor Snake 2


Victor Snake 3


In November, that customer returned for three more DSI Snakes to be used in the Victor diamond mining project in Northern Ontario, Canada.  These systems range in conveying rate from 185 t/h to 422 t/h, with each lifting wet ore approximately 18.5m.  This project is currently in engineering with delivery expected early 2007.  See these units' complete specifications by clicking here or on their pictures.
 
 
Finally, pleased with the success of a previous installation, an eastern Canadian steel mill placed an order for their second DSI Snake in November 2005.  This versatile unit will be handling a variety of materials at rates up to 188 t/h.  This unit, also in engineering, is slated for delivery in mid-2006.  Complete specifications are available by clicking here or on the picture.

In addition to the above, DSI has executed a number of other projects in 2005 which utilized the broad range of services offered.  Highlights include:

  • Structural and mechanical design for the overhaul of a power plant crusher house
  • Field advisory services for land plant and marine installations
  • Conveyor inspections and investigative analyses
  • ExConTech projects for a variety of conveyors
  • High-tech chute design and modifications
  • Expert witnessing

This work, combined with other projects not mentioned, has made for a great 2005.  DSI now looks to the future, with confidence that 2006 will yield even greater success.

DSI Snake Start-Up in Spain

 

Dos Santos International announces

DSI Snake Start-Up

In Northern Spain

Dos Santos International, USA, announces the start-up of their latest DSI Snake-Sandwich High-Angle conveyor, on the 24th of July, 2003, at the Aceralia Steel Mill, near Gijon, Asturias, Spain.

The DSI Snake is part of an expansion to the coal grinding, facilities for the carbon injection to the existing and new blast furnaces.  The DSI Snake elevates the total raw coal through-put to a transfer where a bifurcated chute, with flop gate, allows directing the coal flow to the old and new grinding facilities.

Dos Santos International partnered with PHB Weserhutte, of Gijon, contractor for the expansion project, in the supply, installation and start-up of the DSI Snake.

Operating parameters for the new DSI Snake are summarized in the “Technical Data” table.  The DSI Snake is the latest in Sandwich-Belt High-Angle Conveyor technology, employing all and only conventional conveyor equipment and components.  There are no special pressing mechanisms.  A firm yet gentle hugging pressure, imparted to the conveyed material, is induced entirely by radial pressure due to belt tension and the carrying profile.

Though the first DSI Snake Conveyor for PHB Weserhutte and Aceralia this is yet another Snake in a growing list of sandwich belt installations, by Dos Santos International, since 1998.

DSI Snake "24-7" at Empire Mine

 

Empire's DSI Snake commenced production in August of 2001.  Their fourth sandwich-belt high angle conveyor, it features the highest production, the highest incline and the fastest belt speed (see Technical Data Table below, "Dos Santos International Wins High-Angle Conveyor Order").

Part of an employee driven process improvement, the DSI Snake is helping reduce Empire Mining's production costs, delivering substantial, increasing savings well into the future.

Dos Santos International
 Wins High-Angle Conveyor Order

Empire Iron Mining Partnership, of Palmer, Michigan, USA selected Dos Santos International, in November of 2000, to engineer and supply a DSI Snake Sandwich High Angle Conveyor for the Empire Mine.  The System will deliver crushed iron ore, at 780 long tons per hour (793 t/h), from a roll press, up to a storage and distribution bin.  The DSI unit will be delivered in May of 2001 to begin operation by June.

Empire’s DSI Snake is part of an employee driven process improvement project.  The project will increase plant thru-put by allowing increased utilization of existing crushing and grinding equipment, by re-circulating some of the existing plant product.

The new material transport route resulted in a high incline path, ideal for a DSI Snake Sandwich Conveyor.  Additionally the DSI Snake uses all and only conventional conveyor components and smooth surfaced rubber belts that allow continuous cleaning by belt scrapers.

Though the first DSI Snake Conveyor for Empire this is the fourth sandwich belt system by Dos Santos International since 1998.
