The experience of the operation of suspended electromagnetic iron separators used for the protection of the production equipment against accidental drop of ferromagnetic objects during the transportation of bulk materials by belt conveyors reveals that the common drawback of such devices consists in the insufficiency of the extracting effort created by them at the edges of the working zone [1]. As a result, a part of unwanted ferromagnetics passes through these areas not being separated from the transported non-magnetic material and gets into the operating devices of the production equipment, which results in its breakage. Based on the analysis of the distribution of the field in the working zone of suspended iron separators, to provide the required magnetic intensity and the degree of the field heterogeneity in a relatively big volume of the extraction working zone, a new design of a suspended electromagnetic iron separator was worked out [2]. It is equipped with arch wedged-shaped pole pieces forming a gap situated at an angle to the conveyor longitudinal axis. The use of the iron separator is shown in the production chain is shown in Fig. 1. The purpose of the paper To demonstrate the expediency of the use of archshaped pole pieces in suspended iron separators based on the theoretical and experimental research, to obtain expressions for the calculation of the rational geometry of such pole pieces and to provide specific recommendations as to the relevant modernization of the devices produced in series. The calculation of the poles parameters The magnetic field of the analyzed U-shaped electromagnetic system of the suspended iron separator with arch poles is essentially 3D and it is impossible to use calculation methods from [3-6] as in our case we cannot single out such a direction along which the magnetic field of the system could be assumed quasi-plane-parallel. It caused the necessity for the choice of the method [...]
