Dry magnetic separator

Abstract

The invention relates to a dry magnetic separator. The dry magnetic separator comprises a rack and a charging bin at the top of the rack, wherein a discharging slope is arranged at a discharging opening in the bottom of the charging bin; a first conveying belt is arranged below the discharging slope; a first carrier roller is arranged at one end of the first conveying belt, and a roller shaft is arranged at the other end of the first conveying belt; a second conveying belt is arranged below the roller shaft; a second carrier roller is arranged at one end of the second conveying belt, and a first magnetic roller is arranged at the other end of the second conveying belt; a second separation material inlet and a first separation ore outlet are formed right below the first magnetic roller; a third conveying belt is arranged below the second separation material inlet; a third carrier roller is arranged at one end of the third conveying belt, and a second magnetic roller is arranged at the other end of the third conveying belt; a tailing outlet and a second separation ore outlet are formed right below the second magnetic roller. According to the dry magnetic separator, magnetic separation can be carried out for two times, and materials can be poured uniformly.

Description

technical field [0001] The invention relates to the technical field of magnetic separation, in particular to a dry magnetic separator. Background technique [0002] The dry magnetic separator is a magnetic separation machine for sorting dry magnetic minerals. Compared with the wet magnetic separator, which uses liquid as a diluent to improve the separation efficiency, the dry magnetic separator requires The sorted minerals are dry, and the particles can move freely and form an independent free state, otherwise it will affect the magnetic separation effect, and even cause unseparatable consequences. [0003] Ordinary dry-type magnetic separators usually only screen the raw ore once, but one screening often cannot screen out all the concentrates, and the collection rate of mineral resources is low; some dry-type magnetic separators will also The result is that the screening of the concentrate is incomplete and the metal grade of the concentrate is not high.
