The Biggest Conveyor System on the planet

conveyorrollers

The world is full of conveyor belts. Taken together a system conveyor rollers, these incredible components of technology usually go unnoticed and are underappreciated, but the world would have been a very different place without them. They are used for everything from moving heavy boxes around shipping warehouses to the vital element in food production operations.

Deep within the Western Sahara, in the middle of nothing else but barren wasteland, stands the world’s greatest conveyor belt system. It’s so big actually, that it can be viewed from space. This massive structure extends over 61 miles and it is used to move phosphate stone over the desert.

This web site www.conveyorrollers.co.uk has a lot more information on the main topic of Driven Roller.

The automatic conveyor belt system begins its trip at the Bou Craa Phosphate Mine. Phosphate is required as a crucial agricultural fertiliser and this Moroccan-handled territory has around 85% of the world’s current reserves. Phosphate is sought after around the world and we all consume about Forty million tonnes per year, therefore it is clear why this type of large structure had to be constructed. The belt model is ST 2500 and it is only 80cm wide but has a peak transporting capacity of Two thousand tonnes of raw phosphate stone per hour. The many conveyor rollers that make up this system are crucial to its easy operation.

The Bou Craa phosphate mine was found in The late 1940s by the Spanish. The phosphate deposits located in the area were uncommonly near to the surface and were definitely of really high purity, so it made it a perfect spot to mine, despite the fact that mining didn’t completely begin until the 1960’s. Since the start of operations, the mine continues to expand and now covers an astounding 1,225 hectares. The production in 2001 was 1.5 million metric tonnes of processed phosphate, an abnormally big percentage of the planet’s supply from a single mine.

The belt, that has been functioning for longer than thirty years, finishes its 61 kilometer journey at the El Aain coast where its load is processed and shipped. The belt is not encased and with time, drifting phosphate rock has been transported by the prevailing winds and miles of land south of the belt now appears entirely white from space.

The Bou Craa conveyor belt has such a crucial role to play that if it ever failed, food costs around the globe would substantially increase as stocks of phosphate fertiliser would become scarcer. Who would have imagined a simple conveyor belt can be so tied to the worlds food supply? With a tiny bit of exaggeration, you could state that the conveyor rollers and belt contained within this system are what enables millions of people around the world to eat.

The Bou Craa conveyor is actually a feat of engineering and one of a kind. It really is unlikely that we will see one more conveyor belt of comparable dimensions built in our lives.
