Screw conveyors are used to move bulk materials vertically upwards, horizontally, and at an angle to the horizon. The processes that take place when particles are moved by a screw conveyor in vertical and horizontal directions have been studied. There is a significant difference between them: for transportation in the vertical direction, the necessary conditions must be ensured (sufficient angular speed of rotation of the screw), and for horizontal transportation, the movement of the particle occurs at any angular speed of rotation of the screw. Therefore, when changing the inclination of the axis of the screw, there comes a moment when transportation becomes possible, while it was impossible in the vertical direction. This paper considers the movement of a particle under the condition that it simultaneously contacts two surfaces: the moving surface of the screw and the stationary surface of the cylindrical casing in which the screw rotates. Their common line along which the particle slides is a helical line – the periphery of the screw. The particle slides along the helical line of the rotating screw, i.e., it is in relative motion with respect to it. At the same time, it slides along the surface of the casing, relative to which it is in absolute motion. The trajectory of the particle's absolute motion is its sliding track on the casing surface. When constructing differential equations of the relative motion of particles, the forces applied to the particle were taken into account. The initial position was taken to be the vertical direction of the screw to transport the particle upwards. If an auger in a cylindrical casing is tilted from the vertical direction to a certain angle, then all applied forces (except the force of weight) will also tilt to this angle. On the basis of this, generalized differential equations of the relative motion of a particle during its transportation by an inclined screw were built. They made it possible to derive a generalized mathematical model of the movement of a particle by an inclined screw that rotates inside a fixed casing

“…Therefore, we have developed a design of mechanized solar dryer-grain storage facility. The main equipment for grain moving are auger conveyors (Pezo et al, 2015;Shimizu and Cundall, 2001;Orefice and Khinast, 2017;Rohatynskyi et al, 2019). Therefore, the usage of an auger conveyor was proposed to mechanize grain processing in the solar dryer-grain storage facility.…”

The construction of a solar dryer-grain storage facilities is described. The design of a auger conveyor-distributor of grain for its loading is offered. The dependence of the width of the discharge opening in the casing of the auger conveyor-distributor on its length is obtained. The results of laboratory tests of the auger conveyor-distributor of grain are presented. It is established that the minimum initial width of the drain opening for wheat grain should be not less than 9 mm. The conditions of uniform distribution of grain by the auger conveyor-distributor are justified: the filling factor of the auger interturn space in its loading zone – 0.35; the length of the discharge opening of the charging hopper should be equal to the doubled value of the auger pitch size. In this case, the uneven distribution of grain along the discharge opening will be no more than 5%.
