Abstract

Vertical auger transportation of loose and pulverulent materials is an integral part of many technological processes in various industries and agriculture. The vertical screw conveyors are used in a wide range of various industries and along with such advantages as simple structure, continuity of transportation, integrity, the ability to transport dusty and pungent goods, have a significant drawback - material other than the translational motion in the direction of the axis of the pipeline performs rotational movement in the circumferential direction of the screw speed, which reduces productivity and increases the energy consumption of the conveyor. An adequate mathematical description of this process should allow designers to improve the efficiency of the vertical screw conveyors greatly by calculation and selection of the optimal values of the geometric, kinematic and dynamic parameters of working parts.
