Hua Hua Wang iron ore mining technology more than a collection of minerals expert, mechanical designers, according to the intrinsic properties of the ferrite, the principle of magnetic material adsorption flow path from mineral adsorption different difficulty ferrite, the magnetic field distribution and other links the most reasonable design, after more than three years of trial and error, so that the machine truly iron no dead ends, a significant reduction in cost. This machine is mainly for the mining and mineral development, the use of three national invention patents. Features are as follows: First, the magnetic material specially formulated to ensure low demagnetization rate eight years, so as to achieve a stable iron effect Second, in addition to the CRC in the whole ring road built with stirring impeller. Impeller completely surrounded by iron magnetic field that rotates to drive the pulp to form vortex flow, so that the pulp in order to stabilize the frequency and speed of the flow to be adsorbed on a magnetic material, in addition to iron no dead ends. Third, in addition to space for the installation of iron liner, so that in addition to the iron to form an annular cavity to ensure that all the slurry flows through a high magnetic field. Fourth, in addition to iron out the pulp mouth into the upper space, the slurry flow path longer, most of the iron can be effectively adsorbed. Fifth, in addition to iron magnetic cavity slow rotational motion, smoke filled the iron bar magnet is removed from the machine outside the serum iron, other magnets continue to act on continuously into the pulp in order to achieve a continuous row of iron and iron. Six, and pulp into the direction of movement of the magnet relative direction, just clean, clear iron bar magnet has a magnetic field strength sufficient to capture the iron near the mouth of the omission of small pulp adsorption difficult to achieve refined crude iron to iron the reverse iron absorption, iron absorption subvert the traditional craft. Seven, mixing impeller CVT, the speed can be adjusted according to the pulp density. Eight, power consumption compared to electromagnetic iron machine significantly reduced. Compared with the same effect of electromagnetic machines, ten times lower power consumption.
