I’m bidding for a soil earth moving project from a stock pile to another stock pile, classically we can go by truck haulage system which is less economical than continual bulk haulage (belt Conveyor), accordingly, we are planning to invest in building a conveyor belt moving a soil ( sand with density 1.5-1.6 ton / m3 and lump size less than 4” (150mm)  ) from point A to point B, the Belt conveyor over all distance is 5,000 meters, and the belt conveyor is horizontal with trivial inclinations along the belt route. To achieve the project schedule we have to reach the flow rate is around 3,000 to 3,500 Ton/hour, belt speed is 2.5 to 3.0 meter/Sec, belt width = 1,600 to 1,800 mm, troughing angle = 45 , with the characteristic of material planned to be moved, the surcharge is between 20 to 28 degrees with slim opportunity to reach 30 degrees, repose angle.

What is the specific electric consumption I have to assume through the feasibility study phase?   Can I use the value         0.53     Ws/kg/m  (Ws= Watt second)    which is equal to 0.147    Kwh/Mt/Km

Knowing that the belt Conveyor Route overall length 5.28      Km   (multi-stages and segments)

As a result of this equation and assumption, the SEC will be 0.147   Kw/Mt/Km    kilowatt per metric ton  per Kilometre    , hence the Distance = 5.28 km , then  SEC(weight ) = 0.78 Kwh/Mt   

Appreciate your comments and feedback.
