ABSTRACT:
A belt guidance arrangement for use in a belt conveyor system, such as used in mining operations, includes in one embodiment at least one pair of rollers supported by interconnected frames in vertically spaced substantially horizontal relation so as to enable selective angling between the rollers. An endless conveyor belt is wrapped about the rollers so as to define a reach between the rollers which is twisted generally about a longitudinal twist axis and is subjected to transverse components of tension forces acting on opposite sides of the twist axis upon angled positioning between the rollers. Various embodiments enable the rollers of one or more pairs of rollers to be positioned so that the geometrical relation between the belt engaging peripheral surfaces of the rollers of each pair in the longitudinal direction of belt movement effects balancing of the sum of transverse components of tension forces acting on opposite sides of the longitudinal twist axis of the belt to thereby effect desired training of the belt through the roller pairs. The rollers are preferably formed with profiled configurations which substantially equalize the path lengths of the corresponding longitudinal elements of the belt on opposite sides of the twist axis so as to effect a predetermined differential in the path lengths of the longitudinal belt elements and thereby achieve desired tensile stress distribution in the belt.
