Use of Electromagnetic Impulse System for Transportation of Dry Materials and Solid Bodies

Abstract

In first part of the report motion of magnetic powder materials in a vertical or inclined pipe are investigated. Mathematical models are analyzed, taking into account intensity of a pulse electromagnetic field, parameters of a powder and its interaction with the surface of the pipe and air. Experimental device, including control and measure system with the analysis of parameters by computer, is described. Second part of the report investigates a motion of non-magnetic materials. For this reason an additional magnetic container with open surface is used. After an impulse action the container stops before bound. Non-magnetic materials continue flying motion. In third part of the report the authors investigate motion excitation with impulse generator for plane vibrotransporters. It is shown that this excitation is very stable, because after impulse action the mechanical system continues vibration with a non-periodical motion and stops waiting for next impulse.
