Spiral screw as the working body of a conveyor

In this article the authors consider the motion patterns of how a material particle is moved with a spiral surface in a random direction when the spiral rotates. To obtain the equation of motion, all forces are considered, including the inertia forces applied to the particle on the helical line of the spiral, axis has been considered, which characterizes the geometric characteristics of the helix, a cylindrical casing and particle size in the spiral and helical device. To obtain data on the nature of particle motion, numerical integration of the obtained equations for spiral devices with various parameters was performed.
