Wet magnetic separate

wet magnetic separate

Brief Introduction

The magnetic separate equipment can separate raw materials with different magnetic rigidities. Wet magnetic separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc.

This wet magnetic separation of materials with granularity below 3mm like magnetite, pyrrhotine, bake ore and washingtonite, it's available in cyclic design with process vessel diameters smaller than 3mm. They remove contaminants from the product stream, increasing product purity and plant productivity. In the applications where the product purity is most essential the wet drum separators can use powerful rare earth magnets which can remove very fine and weak contaminants even from dense materials.

Application

Wet magnetic separator is widely used in mineral processing, coal washing and chemical industry, for sorting the wet particle size of 6-10mm. It is suitable for processing fine, weakly magnetic minerals, such as hematite, limonite, ilmenite, manganese, wolframite, tantalum-niobium, and etc. It is also suitable for removing iron and titanium from non-metallic minerals such as quartz, feldspar, nephline, fluorite, ceramic material, and etc. Our company vertical ring and pulsating wet magnetic separatee equipment uses combined force field of magnetism, pulsating fluid and gravity to beneficiate weakly magnetic minerals with the advantages of large beneficial ratio, high recovery, matrix not easy to be blocked and excellent performance.

How wet magnetic separator works?

It is used for removing the non-magnetic minerals in the strong magnetic minerals. When the slurry is injected into the magnetic field, the strong magnetic mineral is adsorbed on the cylinder surface, the weak magnetic and non-magnetic minerals are successively excluded, the strong magnetic minerals adsorbed on the cylinder was taken out of the magnetic field with the rotation of the cylinder. The rotating one is suitable for dry sorting of fine strong magnetic minerals, for the role of high-speed rotation, the amount of rolling of the magnetic particles in Wet magnetic separator is much larger than the ordinary magnetic separator. It has a significant the effect for the destruction of magnetic agglomeration and improves the high-grade ore. There are two kinds of sorted materials: magnetic material and non-magnetic material, the machine is suitable for roughing and selecting materials whose sizes are 6-0mm.

Wet magnetic separator principle

After the ore slurry tank into the tank after the water pipe water to the mine under the influence of mineral particles into the tank was loose state of a mine. In the magnetic field, the magnetic mineral particles together to form the magnetic occurred "magnetic group" or "flux", "magnetic group" or "flux" in the pulp by the magnetic force, to pole movement, and be attracted to the cylinder on. Concentrate magnetic system with the cylinder to the weakest at the edge of magnetic, mineral water spray in the unloading effect of flushing water was discharged into the concentrate tank to complete the magnetic separation process.
