Name of invention:

The inner flow type mineral processing magnetic separator

Abstract:

Our company developed a new structure of magnetic separator, the material flow direction and vertical lines of magnetic force direction of magnetic department, this design increases the concentration area and improve the recovery rate.large particles impurities mixed in the material also can pass, which effectively solves the blockage problem of previous magnetic separator.

Technical field:

The invention relates to a special equipment for dressing.

Purpose and features:

1. Application:

The CNL series permanent inner flow type magnetic separator is suitable for the wet magnetic pre-selection of ferromagnetic materials.

2. Technical features:

(1) the local magnetic system is an external structure, which has advantages of simple maintenance and high magnetic field strength besides the characteristics of the magnetic system.

(2) the magnetic system is a multi-magnetic pole with no gap structure to prevent the adsorption of magnetic materials from falling during operation.

(3). The tank is built with built-in structure, and the area of the constituency can be greatly lengthened to extend the contact time of the material and enhance the beneficiation effect.

(4) it is arranged gradient magnetic field, magnetic Angle 160 °, the magnetic field strength can reach 6000 gs.

(5). The rotary drum is used as the tank for the magnetic separator, which can be used as the longitudinal feed to completely solve the problem of the blockage of the tank.

(6) the inner surface of the magnetic separator is made of alumina ceramic sheet to enhance the wear resistance of the roller.

Background technology:

The conventional magnetic separator has many problems for sand and sand selection.

Invention content:

1. Because ore grade is not high,but we want to have high recovery rate.

2. Whether it is a downflow or a counter-current, it is inevitable that there will be a blockage problem.According to this problem,we designed inner flow type magnetic separator that has Large Angle magnetic system.It is arranged in a gradient on the outer surface of the rotating drum,The material flows through the inside of the rotating drum, passing through the magnetic force line,the ferromagnetic substance is in the magnetic field, with the rotating drum to the top of the roller,When there is no magnetic field, under the action of water pipe and gravity, it falls into the concentrator chute along the longitudinal inclination, and flows to the collecting trough outside the drum.Most tailings flow through the longitudinal tilting of the inner wall of the roller to the tailings dam.
