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 choosing of magnetic separation from fluid ore pulp
Mining low consumed power energy saving 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
Change can generate very high magnetic field gradient and intensity when reaching saturation state, and have very big collecting area, thus adaptation range
Greatly, especially for the collecting to fine particle.What high gradient magnetic separator in the prior art mostly used is that electromagnetic coil is used
In generating magnetic field, its advantage is that magnetic field strength that is easy to control, generating is big, 1.5T or more can achieve, and can be by adjusting
Size of current adjusts magnetic field strength, and disadvantage needs very big it is also obvious that due to using electromagnetic coil when generating magnetic field
Electric current, power consumption is huge, is famous electricity-eating tiger, due to all needing in the not every magnetic dressing process of mineral magnetic separation domain variability
The magnetic field of 1.5T or more is used to carry out magnetic separation, it is therefore, high using electromagnetic wire ring in the occasion of many roughings or low intensity magnetic separation
Gradient magnetic separator often " is wasted one's talent on a petty job ".Moreover, while coil is powered and generates magnetic field due to eddy current effect etc. also
Huge heat can be generated, it is necessary to which controlling calorific value machine could operate normally, therefore using the high gradient of electromagnetic coil magnetic separation
Magnetic separator is required to be equipped with the oil cooling or water cooling circulatory system of a set of complexity, and which further improves the complexity of high gradient magnetic separator
Degree and manufacturing cost.
Summary of the invention
To solve the above-mentioned problems, due to being as previously mentioned the continuous development with material science, permanent-magnet material
Magnetic field strength is more and more stronger, such as the magnetic materials such as rubidium iron boron its magnetic field strengths that can achieve 1T or so, can answer completely
