Magnetic testing rod diameter is 30 mm, magnetic length is 205 mm. Magnetic testing rod is designed for a separation of ferromagnetic impurities from dry mixtures characterized by good loose parameters. The rod is made of DIN 1.4301 stainless steel, and it includes neodymium magnets. Maximum working temperature of this magnetic rod is 80°C. Magnetic induction is on the level No. 4 (core magnetic induction: 14500 G, core tear-off force: 118 N, coat magnetic induction: 10200 G, coat tear-off force: 93 N). Magnetic rod is surface-treated by polishing.
