OPTIMAL TECHNOLOGICAL MODES OF SCREW CONVEYORS

Abstract

Lifting and transport engineering traditionally occupies an important place in the structure of the industrial complex of Ukraine, where specialized enterprises are built for the manufacture of cranes, conveyors, loaders and other equipment for food processing enterprises, and the agro-industrial complex. One of the ways to improve the efficiency of labor in the agricultural sector of the economy and in processing enterprises is the mechanization of heavy and labor-intensive work. When a high degree of mechanization of labor is achieved, conditions are created for the introduction of progressive production methods for processing raw materials and manufacturing finished products, with an increase in its volumes, quality improvement, is the basis for the development of a profitable enterprise. The most labor-intensive and heavy are loading and unloading operations, which occupy a significant amount in the production activities of enterprises. The movement of materials and loading and unloading operations are carried out at many stages of the main production processes, therefore lifting and transport equipment is used to mechanize such operations. Screw conveyors are widely used in various sectors of the national economy to move piece, bulk, viscous-plastic and liquid goods. Most widely screw conveyors are used as one of the links of a complex transport or technological systems. In the sphere of mechanization of loading and unloading operations, during transportation of agricultural goods, screw conveyors are used in the form of a mobile inclined structure, as well as in the form of a mobile vertical conveyor. In agriculture, screw conveyors are most often used. The main advantages of the use of auger norias: practically absent or represents any maintenance; quite convenient implementation of intermediate unloading; tightness that allows to transport any materials.
