Dry strong magnetic disc magnetic separator for sorting a wide selection of less than 2-3 mm and then weakly magnetic minerals and the noble metal ore. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m. Among them, there are many double-disc applications with φ576 mm, so take it as an example.
This body portion is a magnetic device "mountain" shaped electromagnet and rotatable suspension induction disc components. The disc is like a flip-flop dish with a diameter that is about one-half larger than the width of the ore belt. The disc is driven by a worm and worm gear, and the pole between the disc and the electromagnet can be adjusted by the handwheel. Distance (adjustment range 0-20) mm.
In order to prevent clogging, a weak magnetic field pole is placed in the ore cylinder to pre-discharge the ferromagnetic mineral in the feedstock.
Its working principle and sorting process: after the ore is pre-discharged from the ore cylinder, it is evenly discharged onto the ore belt and sent by the belt to the magnetic field gap under the disc. The weak magnetic mineral is subjected to magnetic force. , is sucked onto the tines of the disc, and is rotated to the sides of the belt with the disc, where the strength of the magnetic field drops sharply, so under the action of gravity and centrifugal force, the groove of the magnetic product on both sides of the belt is behind. (generally concentrate); non-magnetic products are transported from the belt to the tailings end into a trough of non-magnetic products (typically tailings).
