Furthermore, belt conveyors do not always work at full load over the entire period of operation. Partial load conditions and even (short-term) idle periods are all part of a belt conveyor's operating regime. In contrast to asynchronous motors, the efficiency of synchronous motors increases in the range of partial load (Fig. 2).

The rotating resistance of idler rollers in belt conveyor systems occurs due to the friction of the rolling elements in the bearings, the viscous drag of the lubricant and the friction of the contact lip seals. The resistance force typically contributes between 5 to 15% [6,7] of the motion resistance of long horizontal belt conveyors.

Reference to Fig. 2 shows that the reclaim hoppers, feeders and conveyor are offset an amount defined by "x" from the centre of the stockpile.This is deliberate. Since the reclaim volume is controlled by the draw-down HD measured from the free surface of the pile, it can be shown that the improvement in live capacity is possible over that achieved by locating the reclaim centrally.
