Abstract:In order to study characteristics of different materials conveyed by vertical screw conveyors,an experimental test platform was independently designed.By changing screw shaft speed and feeding head speed,an analysis was conducted on the impact of material types (sand and soybeans)on the conveying performance indexes (productivity and energy consumption)of the screw conveyor.The results show that to achieve the best conveying performance of the screw conveyor,changing the screw shaft speed and the feeding head speed is the most direct and effective methods.With the increase of the screw shaft speed,the conveying performance will gradually improve and then decline,so in engineering design can not blindly increase the screw shaft speed.The screw conveyor has the best ratio of the screw shaft speed and the feeding head speed,that is,the best speed ratio.The screw conveyor has the best conveying performance with the best speed ratio.The best speed ratio when conveying sand and soybeans is basically the same of 3 to 4.

Keywords:vertical screw conveyor;conveying performance;feeding head speed;screw shaft speed;best speed ratio
