Description

Wet magnetic separator for mine field

Technical Field

The utility model relates to a magnet separator technical field specifically is a wet-type magnet separator is used in mine field.

Background

The wet magnetic separator is a screening device for removing iron powder used for recycling of powdery granules. After the ore pulp flows into the tank body through the ore feeding box, under the action of water flow of the ore feeding spray pipe, ore particles enter an ore feeding area of the tank body in a loose state. Under the action of the magnetic field, magnetic particles are magnetically aggregated to form magnetic groups or magnetic chains, and the magnetic groups or the magnetic chains are moved to the magnetic poles under the action of magnetic force in the ore pulp and are adsorbed on the cylinder. Because the polarities of the magnetic poles are alternately arranged along the rotating direction of the cylinder and are fixed during working, when the magnetic lumps or the magnetic chains rotate along with the cylinder, the magnetic stirring phenomenon is generated due to the alternation of the magnetic poles, nonmagnetic minerals such as gangue and the like mixed in the magnetic lumps or the magnetic chains fall off during turning, and finally the magnetic lumps or the magnetic chains attracted on the surface of the cylinder are concentrate. The magnetic separator is widely used for resource recovery, is suitable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, ilmenite and the like with the granularity of less than 3mm, and is also used for iron removal operation of materials such as coal, non-metal ore, building materials and the like.
