Sandwich Belt Conveyors are so named due to the manner in which the material is ‘Sandwiched’ between two rubber belts before it is inclined at angles up to 90 degrees. Material is ‘hugged’ by the belts throughout the inclined section to ensure that it does not slide back down the incline, even if the conveyor trips.
A Sandwich Belt Conveyor consists of two endless belt conveyors that share a common load carrying path. The top and bottom belts are independently driven and tensioned. Along the carrying path the top and bottom belts are alternately supported against closely spaced troughing idlers. Radial pressure, due to belt tension and the curving profile, continuously hugs the material that is Sandwich between the two belts. Internal friction is developed and bulk material can be conveyed at any high angle up to the Vertical.
