Description
Technical field
The present invention relates to a kind of high gradient magnetic separators, more particularly, to a kind of for carrying out the double of magnetic separation from fluid ore pulp
Join continuous type energy conservation high gradient magnetic separator.
Background technique
It carries out magnetic separation to minerals using magnetic field in the history that mankind's mineral extract to have been one hundred years of history, just
The magnetic separator of phase is not widely used due to the restriction of the basic science such as theoretical and material development.It was opened from 1855
Begin after generating magnetic field using electromagnet, the theory and practice of magnetic separator is just gradually improved, and has emerged in industry various types of
Industrial magnetic plant, magnetic method are just widely used in terms of the ore dressing of iron ore.After nineteen sixties,
With the continuous development of material science, the magnetic field strength of permanent-magnet material is more and more stronger, and some magnetic separators gradually start using permanent magnetism
Body carries out magnetic separation, especially weak magnetic separator gradually permanent magnetism.
High gradient magnetic separator is the magnetic separation technique that later 1960s early seventies grow up, main
Feature is exactly: the magnetic medium of magnetic conduction being filled in the inner cavity of spiral magnetic system as separating medium.Since magnetic separation medium is in magnetic
