POSSIBILITIES OF OPTIMUM SELECTION OF VALUE OF PARAMETERS OF SCRAPER PIPE CONVEYOR

Abstract

Still growing requirements connected with environmental protection, work safety, but also many advantages of scraper pipe conveyors caused that they find more and more wide applications in transport of fine grained, bulk, dusty materials and pulp in chemical, ceramic, aluminium industry, cement mills, electric plants and steelworks. Those conveyors have: simple construction and maintenance, small dimensions in crosswise section, easy configuration of routes, transport materials at high temperatures (even at 700 oC). Those conveyors have also disadvantages; their great resistances of movement (friction) causing significant friction wear of parts, which is essential problem in exploitation. Parameters connected with conveyor construction, route configuration and transported materials properties have essential influence on those resistances.

In the paper had been indicated possibilities of selection of such scraper pipe conveyor basic parameters like internal pipe diameter, distance between scrapers and speed, at which resistances of movement or needed drive power are minimal. It has essential meaning for rational designing and exploitation of scraper pipe conveyors.
