Abstract
A high speed belt to belt transfer chute useful in handling, without modification or adjustments, material ranging from sticky clay and fine dust to large rocks. The generalized chute is designed either to bend the material flow to the vertical after it has left a leading belt or, conversely, to direct material moving vertically downward into the direction of a following belt. The chute is constructed of individually replaceable, ribbed elements, which may be repositioned and replaced as they wear in order to maintain the same directed, controlled flow of material, while minimizing the replacement cost and downtime. A two-unit chute may be constructed with an upper unit for transferring material from a conveying belt to a second, lower unit which transfers the material onto a following belt, with the vertical distance between them fixed so that the energy lost by the material in friction and impact on both units may be made up in gravitational acceleration between the belts, thereby maintaining the speed of solids and the rate at which the materials are deposited onto the following belt.
