Abstract
The article presents an experimental stand for laboratory research of a screw conveyor with a bladed working body. Based on the results of experimental studies, the corresponding response surface regression equations were constructed to establish the influence of controllable factors upon the degree of damage to the grain materials. It was established that the main factor affecting the increase in the amount of the grain damage was factor x3(n), the rotation frequency of the bladed working body. The increase in factors x1(D) and x2(ψ) led to a decrease in the amount of the grain damage. Based on the results of comparative experimental studies to determine the degree of damage to the grain material during its transportation by the screw and blade working bodies, it was established that the bladed working body provided a reduction in the degree of damage to the grain material with a simpler manufacturing technology.
