One of the prerequisites of high competitive ability of enterprises is the further improvement of structural and technological parameters of screw conveyors with advanced technological features that promotes productivity and work quality, as well as requires a fundamentally new approach to the creation and use of highly efficient energy-saving technical systems. New types of designs of screw conveyors with advanced technological capabilities for transportation, ventilation, mixing, grinding, moisturing, squeezing of juice and other operations are proposed. The characteristics of screw conveyors is that in their design the new types of mechanisms were introduced such as the principle of vibration during transportation to avoid dead zones, which reduce conveyor productivity, increase power consumption and reduce transportation process. The design of conveyor with gear-lard mechanism that provides a significant improvement in the quality of mixing is proposed. New designs of screw conveyors with improved technical and economic parameters based on the principle of centrifugal and gravitational action, design versatility with the ability to perform multiple operations are available now. Analytical dependences to determine the performance of screw conveyors with regard to the physical and mechanical properties of transporting materials, construction features of additional nodes and kinematic and technological parameters are developed. Analytical expressions for calculating the structural parameters of the mechanism of larding the screw conveyor with gear-lard mechanism are analyzed as well as the screw conveyor of a mixer with closed-cycle operation. Analytical dependences for determining the minimum angular speed of rotation of conveyor gear-lard mechanism, are developed as well as the analytical dependence for determining the cost of power consumption of the proposed modifications of screw conveyors. The proposed designs of new types of screw conveyors for various additional manufacturing operations are patented.
