In the second step, the flushing water below flush the raw materials back for the second separation. This time the flowing direction of the raw materials is opposite to the rotary direction of the magnetic drum. Also, the flushing water above helps to flush the iron magnetite into the ore concentrate box

The material also have flow arrangement according the the material dimension. The major technical leader in our factory is from Japan and has been studying this field for over 15 years. The other factory is in Ningbo and is specialized in manufacturing NdFeB magnets

use weak wet magnetic field to sort out the strong magnetic ore, or eliminating the strong magnetic minerals mixed in nonmagnetic minerals. The fixed one is mainly use in weak magnetic field to separate the fine particle strong magnetic materials, or eliminating the strong magnetic materials in the nonmagnetic ores. Magnetic Separator is designated for wet magnetic separating of material with granularity below 3mm, such as magnetite, pyrrhotine, roasted ore and washingtonite

high precision, advanced tin ore magnetic separator

The strong magnetic minerals and magnetic minerals are divided into two kinds of material: non-magnetic material and magnetic material. Magnetic separator is suitable for wet magnetic separation of materials such as magnetite, calcined ore, etc. The magnetic source is permanent magnetic NdFeB materials which is the king of magnetism

dry magnetic separator, magnetic separator working

[Improvement]: This patent product is newly developed by Xinhai, and patent application is No.: 201410328639.2. Compared to conventional cylinder and dry magnetic separator,the magnetic wrapping angle of this patented product is 360°. The magnetic systems all adopt Nd-Fe-B magnetics with high magnetic energy product and high coercivity, strong magnetic density and high affect depth. The demagnetization rate of the magnetic density within 8 years is no more than 5%

This patented product is a kind of upgrading equipment based on conventional magnetic roller or conventional dry separator. When it is working, the magnetic minerals will take rapid magnetic reversal and magnetic agitation, which will significantly reduce the number of non-magnetic (weak magnetic) minerals in the magnetic minerals. In this way, the efficient separation of magnetic minerals and non-magnetic (weak magnetic) minerals will be realized, and fine magnetic minerals and coarse magnetic minerals will not get lost

This patented product solves the eddy current heating problem, ore sticking problem for separation cylinder, and mine unloading problem of conventional 360 degree rotating magnetic dry separator. The conventional 360 degree rotating magnetic dry separator must use the belt to unload the mine by the outside of it, therefore the magnetic minerals are easy to enter the central space between the inside belt and sorting tank. The magnetic minerals attached on the sur­face of sorting tank cannot fall off automatically (cannot unload mine automatically). As the accumulation grows, the separation effect is affected. What's worse, rapid wear of sorting tank body as well as the belt will be caused, and the normal operation of production will be seriously affected

Under the condition that the grade of the dry tailings is equal to or even lower than that of conventional magnetic roll­er or conventional dry separator, for high-grade and lean magnetite with different features, by adjusting corresponding technical parameters and structure, about 10%-30% tailings discharging and about 1.0%-8.7% of concentration grade can be increased compared to conventional magnetic roller or conventional dry separator. The concentrate grade of dry separation is significantly enhanced compared to the feeding grade. Under the conditions of fine crushing size of below 2 mm and coarse dissemination size, more than 60% grade of the dry separation concentrate can usually be obtained directly. In the actual production, if one patented product can process 1 million tons of raw ore every year (150 t/h, 1million t/a), it can discharge an extra 0.1-0.3million tons of the qualified dry tailings, and reduce 0.1-0.3 million tons of waste rocks before ore grinding every year, which can reduce the concentration ratio and the cost of production sharply. If the production costs such as the ore grinding, magnetic separation and the wet separation tailing processing is 30 yuan/ton, one set of the pat­ented product can save the production costs of about 3-9 million yuan. Under the condition of the same amount of mining, the output of the iron concentrate basically remains unchanged

As the amount of the waste rocks into the mill is reduced, the annual capacity of the ball mill is actually increased by (100,000-300,000 t/a) for one patented product, and the iron powder production is correspondingly increased without any investment in plant expansion, increase of grinding and mineral processing equipment, roads, water supply, tailing process­ing, etc., and with almost no increase of electricity load and labors, the economic and resource environmental benefits are significant

Before grinding, a large number of qualified dry tailings can be discarded, with the convenient treatment, they can be direct­ly transported to the hillock, and also can be used as building stones or river sand to create certain economic benefits, while by which the number of wet tailings are reduced and the lifespan of tailings pond is improved. The magnetic wrapping angle is 360 degree. The magnetic systems all adopt Nd-Fe-B magnets with high magnetic energy product and high coercivity, strong magnetic density and high affect depth. The demagnetization rate of the magnetic den­sity within 8 years is no more than 5%

The separator working principle: In the separation area of the separation cylinder, the centrifugal force and gravitation of magnetic minerals mingled with non-magnetic minerals are much less than the magnetic force. With the adsorption of the magnetic force and the joint action of the magnetic turn and agitation of magnetic minerals, the mag­netic minerals will move to the inter layer gradually. When the magnetic minerals rotate to the ore unloading area with the separation cylinder, as the rotation magnetic system is eccentric, the magnetic density of the ore unloading area for the separation cylinder is extremely weak, and most of the magnetic minerals can fall off automatically. A small quantity of magnetic minerals not falling off will be adsorbed to the external surface of the ore unloading cylinder with higher magnetic density when rotating to the position nearby the ore unloading cylinder so as to realize the automatic unloading of magnetic minerals

drum magnetic separator, drum type magnetic separator

The materials are uniformly fed to the belt. When materials go through the permanent magnetic drum, the non-magnetic and low-magnetic particles will leave the belt surface because of the centrifugal force and gravitation. Meanwhile, strong-magnetic particles are absorbed to the belt by the magnetic force and then fall into the magnetic trough when the belt leaving the magnetic pulley
