Description

The 3-stage magnetic separator is a type of dry magnetic separator with high magnetic field intensity, using a permanent magnet and drum. It is used for the beneficiation and purification of materials with low magnetic susceptibility and a particle size range of 0.1–25 mm. The magnets used in production are Neodymium magnets, which are currently among the strongest magnets worldwide compared to equivalent machines. With this feature and special magnet arrays, high attraction forces are applied to the magnetic drum. The high magnetic forces achieved allow the separation of magnetic minerals with low magnetic susceptibility and very fine particle sizes with high efficiency.

Operation

The machine generally consists of a conveying frame, feed hopper, feeder, magnetic and non-magnetic rollers, product conveyor belt, drive motor, and control panel. Magnetic separation drums are generally used after crushing and screening processes. Minerals that have passed through these processes with a size of -25 mm and a maximum moisture content of 5% flow smoothly over the conveyor belt with the help of the feed hopper and feeder. The conveyor belt runs over a magnetic and a non-magnetic roller. When the material on the belt reaches the magnetic roller, the non-magnetic particles are discharged with the help of centrifugal force and directed into the non-magnetic material chute. The magnetic particles continue to be carried along the drum due to the magnetic roller until they are released from the roller’s magnetic force. Once released, these particles are directed into the magnetic material chute.

Industries

It is used for removing iron from ceramic raw materials and industrial raw materials, as well as in ore beneficiation operations. In addition, it is used in the following applications: high-grade quartz purification, magnesite beneficiation, beach sand/mineral sand processing, dolomite and limestone purification, foundry sand cleaning, refractory raw material purification, boron beneficiation, chromite beneficiation, bauxite processing, feldspar purification, glass sand cleaning, and silica sand purification.
