In recent years, with the rising price of iron and steel raw materials iron powder rises, the profits of sand iron selecting of profit increase. Thus, special machinery and river sand dressing equipments, magnetic separator and other series ore dressing equipments have been nationally popularized in many areas. At the same time, they are all inseparable from the magnetic separator.
Magnetic separation equipment magnetite beneficiation equipment. The choice of the magnetic separator production efficiency and cost of the dressing to a large extent.Good magnetic separator magnetic system, using high quality ferrite material or compound is made with rare earth magnet drum table the average magnetic flux density of 100 ~ 600mT. The user needs to provide the downstream half countercurrent, counterflow, and other magnetic separation of the different tables. The separator has a simple structure, large capacity, easy to operate, easy to maintain.Intact the monomorphous was octahedral or rhombic dodecahedron, was a rhombic dodecahedron, the diamond surface often long diagonal stripes parallel to the crystal surface.
How does those dressing equipment selecting the iron from the sand? The general working principle of those ore dressing equipments: they separate the magnetic iron from the river sand by the magnetic separation system of magnetic separator. And the general digging sand iron dressing equipment is composed by bucket dredging system, screening system, magnetic separating system, tail sand removal system, driving system.
The feeding system of this dressing equipment is a chain bucket dredging system, the river sand elevated by chain bucket include different sizes' stones, in order to protect the safety of magnetic separator, the raw materials must screened by screening machinery at first. According to different channel environment, it is different. Generally speaking, river with less stone, little diameter is with a comparatively good self-oscillation and is convenient to repair and power saving. While the river with much stone, large diameter should use a roller screen. Stones after screened generally flow directly into the river, among which of economic value will convey to shore for sale. Magnetic separation system mainly includes magnetic separator and water concentration system.
The effect of the water concentration system is to raise the grade of the iron powder, which generally can be adjusted in a range. The sand removal system in the end is convey the final iron far from the machinery to ensure that the machine can work normally. It generally includes gravity flow type, belt conveying type, pumping sand pump type three kind of forms. Of course it is according to the specific environment of the river. After the magnetic separation, the iron content of the sand is increased to 98% or more, which can fully meet the needs of users.
After the ore slurry tank into the tank after the water pipe water to the mine under the influence of mineral particles showed a loose state to enter the tank of mine. In the magnetic field, magnetic magnetic mineral particles occur together and form a 'magnetic group' or 'flux', 'magnetic group' or 'flux' in the pulp by the magnetic effect, movement to the pole, and was adsorbed on the cylinder . As the magnetic polarity along the cylinder rotation is alternately arranged, and fixed and at work, 'magnetic group' or 'flux' in the rotation with the cylinder, due to alternating magnetic poles arising from the phenomenon of magnetic stirring, is mixed in the 'magnetic group' or 'flux' in the non-magnetic gangue minerals such as falling down and turning in, eventually being sucked in the cylinder surface 'magnetic group' or 'magnetic lotus' is the concentrate .Concentrate the magnetic lines to the edge of the cylinder with the weakest at the magnetic field in the discharge of mine water spray rinse under water to the concentrate tank to be unloaded, if the whole magnetic roller, brush roller unloading ore is conducted . Non-magnetic or weakly magnetic minerals are left with the pulp in the pulp discharged outside the tank , that is tailings.
