Abstract
Spherically-shaped rolling solids are separated from irregularly-shaped nonrolling solids with an inclined conveyor belt separating system. A dry mixture of the solids is fed onto a section of a continuously upward moving, appropriately inclined conveyor belt. Most of the nonrolling solids eventually move up with the belt and are then moved in a sideways, upward direction or directions off a side of the belt. Most of the rolling solids move down the belt and are then moved in a sideways, downward direction or directions off a side of the belt. These changes in direction of movment of the rolling and nonrolling solids provide several advantages, including the freeing of trapped solids of the other class so that the freed solids may move up or down the belt as the case may be. The solids feed stream and the direction and rate of flow of the solids of the belt may be additionally controlled. The upper surface of the conveyor belt may also be divided into two or more distinct separating sections. In this manner, the separating efficiency and surface utilization of a continuously restored, conveyor belt separating system is increased, while carry-over or loss of desirable solids is reduced. The separating system is especially useful for separating spherical solid heat carriers from spent shale solids in an oil shale retorting facility.
