Dynamic characteristic analysis of vertical screw conveyor in …
The maximum mass flow rate of Case 1 is approximately 250 t/h, while that of Case 4 is about 180 t/h. Case 1 is a traditional vertical screw conveyor with constant screw section, and the others are in variable screw section condition. The decreasing mass flow rate of Case 4 is resulted from the reducing filling rate in the conveyor.

Types of screw conveyors include bottom conveyors and centerless screw conveyors. Bottom conveyors use multiple screws in an open trough. Centerless, or shaftless, screw conveyors do not contain a central shaft and instead consist of an empty helix. This design still moves the substrate but allows for more freedom within the casing. …
