Embodiment Construction

[0011] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0012] As shown in the figure, this embodiment provides a magnetic separation system, including a primary magnetic separation unit 1 and a secondary magnetic separation unit 2 .

[0013] The primary magnetic separation unit 1 includes a conveying belt 11 driven by a motor (not shown in the figure) for conveying materials, and the conveying belt 11 bypasses the primary magnetic field in front (the direction in which the conveying belt 11 conveys the material). The selection drum 12, the surface magnetic induction of the primary magnetic separation drum 12 is 1000Gs-2000Gs.

[0014] Described secondary magnetic separation unit 2 comprises feeder 21 and secondary magnetic separation drum 22, and the feeding plate 211 of described feeder 21 is arranged on the front lower side of described primary magnetic separation drum 12, thereby makes described p...

Abstract

The invention discloses a magnetic separation system including a primary magnetic separation unit and a secondary magnetic separation unit; the primary magnetic separation unit includes a primary magnetic separation drum, and the surface magnetic induction intensity of the primary magnetic separation drum is 1000 Gs to 2000 Gs; the secondary magnetic separation unit includes a secondary magnetic separation drum, and the surface magnetic induction intensity of the second magnetic separation drum is 4000 Gs to 5000 Gs. The magnetic separation system has the following advantages: 1, a contact type magnetic separation process can improve the recovery rate of ferromagnetic materials; 2, a process with addition of first-section low-intensity magnetic separation and second-section high-intensity magnetic separation reduces damage opportunity to equipment, is in favor of equipment service life, and has less equipment maintenance time; and 3, the process with addition of first-section low-intensity magnetic separation and second-section high-intensity magnetic separation refines the ferromagnetic material types, an iron-containing material is singled separated out so as to be more conducive to back-end aluminum smelting, the aluminum smelting time is shortened, the energy is reduced and the efficiency is increased.

Description

technical field [0001] The invention relates to a magnetic separation system, which belongs to the technical field of mechanical equipment for sorting materials. Background technique [0002] There are many kinds of magnetic separators in the prior art, among which the magnetic drum type magnetic separator is more commonly used. Magnetic pulley, also known as magnetic pulley, has two types of permanent magnet and electromagnetic. Its structure is simple, and it can be directly installed on the head of the belt conveyor, or it can be configured as a separate dry magnetic separator. The magnetic material is absorbed when it moves to the top of the drum with the belt, and falls off automatically when it turns to the bottom, while the non-magnetic material falls directly along the horizontal parabolic trajectory. The magnetic drum can be used for iron removal of materials, especially for magnetite nugget pre-selection. Magnetic separators are widely used in the separation of ...
