The OLDS elevator is an Australian designed variant of a screw conveyor in which the screw flight remains stationary and the casing rotates. This device potentially offers several advantages over a screw elevator, though due to its recent conception, there is a significant amount about its operation that is not fully understood. This paper presents both DEM simulation results and laboratory data gained...
Screw conveyors are used extensively in agriculture and industry for transporting and/or elevating bulk materials over short to medium distances. They are very effective conveying devices for dry particulate solids, giving good control over the throughput. Despite their apparent simplicity, the mechanics of the transportation action is very complex and designers have tended to rely heavily on empirical...
