Regenerative Belt Conveyor versus Haul Truck-Based ...

Belt conveyor drive power is a function of belt speed multiplied by the total belt conveyor resistances to motion, which is the sum of primary (main—acting along the whole conveyor route), secondary (occurring at specific points only—pulleys, cleaning devices, etc.) and gradient resistances (see Figure 3). It is worth noting that in the ...
