Вплив потоку сипкого матеріалу на техніко-економічні показники роботи гвинтового конвеєра

The paper covers theoretical investigations of the movement of bulk material flow when it is fed by a pneumatic screw conveyor. Process calculation of the impact of bulk material particles during their transportation in guiding covers has been conducted. A mathematical model, which characterizes the overall energy spent on the impact of two particles, depending on impact velocity, physical and mechanical properties of bodies and impact conditions, has been developed. The limits of design and kinematic parameters that provide the effective application of pneumatic screw conveyors for transporting bulk materials have been defined

The article presents the justification of rational parameters of the operating parts of a pneumoconveyor screw. The dependences of pressure screw efficiency on the change in design and kinematic parameters and process variables of a screw and on loose material characteristics have been considered. In addition, general analysis of the choice substantiation of a feeder pressure screw diameter and the cross-sectional area of a hopper loading opening, which provides the required efficiency of a pneumoconveyor screw, has been conducted
