The permanent NdFeB magnets in the circuits for magnetic filters and the first technological tests

The article provides information about the results of test work dealing with the assembly of magnetic circuits from NdFeB material designated for magnetic filters. It describes the way in which a further increase in the value of magnetic induction was reached in the middle of the air gap in the case of a circuit assembled from two opposing magnetic blocks. It also informs about the assemblage of magnetic circuits with a considerably higher volume of the separation zone suitable for industrial purposes. In all the tested cases, the dependence of the magnetic induction in the middle of the air gap on the width is shown, including a corresponding graphic representation and a comparison with the results obtained in the previous testing period. With a new magnetic filter the cleaning of ceramic suspension was carried out. The results of an industrial scale test are presented.
