The High Gradient Magnetic Separators (HGMS) are used in many magnetic separation applications. wet HGMS is usually used for separating fine-grained iron magnetite from non-magnetic materials. Its composite magnetic system consists of high performance rare earth permanent magnet (main magnetic source) and ferrite permanent magnet. Among these are the processing of more strongly magnetic minerals of Fe, Co and Ni as well as less magnetic minerals such as rare earths and industrial minerals, which normally are not regarded as treatable by magnetic processes. Even weakly, para-magnetic materials can be processed by the HGMS including brightening of kaolin clays, separation of galena, chalcopyrite and sphalerite; removing Fe and Cr from glass sand; and cleaning of refractory materials, coal and phosphate concentrates., HGMS is capable of handling and recovering particles down to extremely fine sizes due to the possibility to choose a suitable matrix grade with large collection area and to control the slurry velocity during the separation process.

Why use high gradient magnetic separator to purify feldspar?
?

Whiteness/brightness is a key index in the industrial purpose feldspar. In the run of mine, ferrous substances are the main coloration compositions, which exist in the form of biotite, ilmenite, chlorite and tourmaline.


These substances are few, fine and weak magnetic materials. Unlike the grinding metal from crusher, It is hard to extract them with traditional drum magnetic separator or roll magnetic separator. The separator shall be strong with higher magnetic intensity and more suitable to finer minerals. High gradient magnetic separator performances better.

Why high gradient is necessary?
?

Background magnetic field intensity of the high gradient magnetic separator is up to 12000 GS, and gradient intensity, which generated by the matrix in the bkg. Magnetic fields, is up to 30000 GS. It captures not only grinding metals, but also feebly magnetic impurities.

?

Why wet separation?
?

For industrial use, particle size of feldspar powder shall be mostly undersize 200 meshes. The fine magnetic particle in feldspar is hard to be attached by dry magnetic separator. While, if mix the particle with water, they will be easier to be extracted.

Working principle

?

When the raw materials flow into the tank body of the wet magnetic separator , firstly, the flowing direction of the raw materials is the same as the rotary direction of the magnetic drum, the iron magnetite materials are attracted to the surface of drum.

?

Secondly, the flushing water below flush the raw materials back for the second separation.

?

This time the flowing direction of the raw materials is oppo site to the rotary direction of the magnetic drum.

?

Then along with the rotation of drum, the iron magnetite materials on the surface of drum will finally leave the magnetic field and fall to the ore concentrate box under gravity.

?

Also, the flushing water above helps to flush the iron magnetite into the ore concentrate box. The weak magnetic and non-magnetic materials can not be attracted and will flow to the discharge pipe for tailings.
