Abstract

Results are reported from studies undertaken to improve the efficiency of screens that are equipped with linear electromagnetic motors and undergo low-frequency resonance during service. The article substantiates the indices that were found to characterize the efficiency of the screens and the improvement made in the design of their main component – the vibration exciter. An efficient size was determined for the air gap in the motors.
