Using magnets for particle extraction from powder flow




A model is explored for the extraction of ferromagnetic metallic particles using a magnetic filtration system. These metallic particles, which are transported by a powder flow may be fragments resulting from the standard wear and tear on industrial machinery. A project of this nature was brought to the 2015 Mathematics and Statistics in Industry NZ Study Group. Possible configurations of the magnetic filtration systems are considered with the target of better particle capture. The dependence of the model on the metallic particle's release zone and velocity is investigated. Monte-Carlo simulations are conducted for cases using perpendicular as well as parallel magnetic rods. The results confirm the efficacy of parallel offset rods and emphasise the importance of dense rod placement. The approach could be used to explore further alternative rod arrangements in advance of experimental implementation. References
