Abstract

This paper deals with optimization of ferrite magnet production. The study is divided into two parts. The first part introduces general information about magnets and their division. The process of the magnet is described in detail. In the second, experimental part of the input raw material, ferrite metal powder, the basic mechanical and physical parameters were determined, including the angle of internal friction, the particle size distribution, the particle shape and the flow function, serving for a more detailed description of the behaviour of the material throughout the technological line. On the basis of evaluation of measured data, specific steps were proposed to optimize ferrite magnet production and general optimization of weak points of storage and feeding processes. The support of Discrete Element Method was used for the final hopper design.

Keywords: magnet, ferrite powder, angle of internal friction, hopper
