Description

This invention relates to the beneficiation of minerals.

Known electromagnetic separator, which includes an electromagnetic system with pole pieces installed with a gap, feeder, receivers of products divided) 1.

The disadvantage of the separator is low productivity.

Also known is an electromagnetic separator, which includes a chamber equipped with nozzles of the input of the material being processed and a section of products 1, an electromagnetic system placed on the outside of the chamber, and a polyradiation medium of plates made of ferromagnetic material and placed inside the chamber parallel to each other with a gap, while the plates Adjacent to the walls of the chamber are made with one-sided triangular shaped triangular shape facing the inside of chamber 2.

The disadvantages of this separator are the low efficiency of the separation process and the low productivity.

The purpose of the invention is to increase the separator productivity and the efficiency of the separation process.

This goal is achieved by the fact that the plates are zigzagged and placed

with the formation of the same gap between adjacent plates at all points of their surfaces.

Zigzag vertices can be made rounded.

It is advisable to make the separator multi-chamber with the sequential placement of chambers and the installation of plates in different chambers with different clearance. FIG. 1 shows a separator, a cross section; on phpg. 2 and 3 - types of plates from a ferromagnetic mat, rial.

The separator includes a chamber 1, an electromagnetic system with poles 2 and 3, a polygradient medium made of plates 4 adjacent to the walls of the chamber / and plates 5, made zigzag with the placement of the protrusions of the prothp plates of the depressions and opposite plates, while the zigzags can have a triangular or trapezoidal section, and the tops of the zigzags can be made rounded.

The separator works as follows.

The source material is fed into the chamber / and moves along the plates of ferromagnetic material. The magnetic particles are driven by the plates 4 and 5, and the non-magnetic parts 1xx pass through the chamber / and

enter the receiver of the non-magnetic fraction. After an assigned period of time, the supply of the starting material is stopped, the power of the electromagite system is turned off, and the polygradient medium is regenerated with the magnetic fraction B unloaded corresponding to the treblemNI.

The implementation of plates 5 in a zigzag manner with the placement of the protrusions of the protiiB plates of the opposing ilastins allows eliminating the inconsistency of the gap between the chalk and food plates n, the successors-io, to increase the capacity of the separator. Placing the plates with the formation of the same gap between adjacent plates at all points on their surfaces allows ei to ensure a minimum of inactive zones in the working gap, which, along with the multi-chamber making of the senator and installing the plates in different chambers with different gaps, improves the efficiency of the separation process.

Thus, the execution of the zig plates: -: Shaped and placing them to form the same gap between adjacent plates at all points on their surfaces, making the multi-chamber sewer and installing the plates in different chambers with different gap make it possible to increase the separator productivity and efficiency of the separation process.
