Dependence of Torque on Rotational Speed in A Screw Conveyor Transporting Undried Cotton

Abstract

This article presents a theoretical investigation of the dependence of the torque generated during the operation of a screw conveyor transporting undried cotton on the rotational speed. The study is based on mechanical modeling and analytical calculations, taking into account the fibrous structure, high moisture content, and compressibility of undried cotton. A mathematical model describing the nonlinear relationship between torque and rotational speed is proposed. Based on theoretical graphs, the energy load of the screw conveyor is analyzed, and the existence of an optimal operating regime is substantiated. The obtained results can be applied in the design of screw conveyors and in the selection of electric motor power.
