Installation for the investigation of screw working bodies with elastic surfaces and the results of their experimental tests

Abstract

Screw conveyors are widely used in various sectors of the economy determining specific requirements for them. One of such requirements is the possibility of safe movement of brittle elements and products with possible increased damage (injury) in pharmaceutical industry, electronics, food industry, as well as in agricultural production during the transportation of seed grain materials. The theoretical substantiation of the increase of efficiency of bulk cargoes transportation by screw conveyors is given in this paper. The problem of their progressive structures development with the possibility of minimal damage of grain materials remains important. The paper presents Recommendations for the auger rotation speed selection in order to minimize the damage of brittle elements and products are presented in this paper. The rational angle at which productivity of the screw conveyor reaches its maximum values is deteermined.
