Abstract
The utility model relates to a magnetic medium for equipment of high grads magnetic separation, whose surface of steel wire is provided with many jags. The utility model is characterized in that the magnetic medium generates bigger magnetic field grads and magnetic field force than that of the existing steel magnetic media after magnetized, so the magnetic medium has higher standard of ore dressing technology. Besides, the utility model with little resistance to ore slurry hardly generates the phenomenon of clogging magnetic media, and has the advantages of easy to clean and easy to replace.
Description
The utility model is the used magnetizing mediums of a kind of high gradient magnetic separating apparatus.
Present used magnetizing mediums, its structure are the rectangular thin velvet-like body of growing in cross section, and that area of section is bigger is (200～300) * 50 μ m
2, that area of section is less is (20～50) * 10 μ m
2This magnetizing mediums colony that is made up of thin and long velvet-like body is arranged at and is fiber varicosity shape in the magnetic separating apparatus.When magnetizing field lower magnetic force line passes through every magnetizing mediums, shrink on the two-dimensional space direction by the original magnetic line of force parallel to each other, thereby on the faceted pebble of every magnetizing mediums, produce bigger magnetic field force.Though its capture rate was higher when this magnetizing mediums was used for separating magnetic-particle, but be mingled with more non-magnetic particle in the isolated magnetic-particle, thereby the precision that mineral are separated is lower, and since bigger to the resistance of ore pulp, the magnetizing mediums clogging easily produced.In addition, this magnetizing mediums is easy cleaning, replacing not, and its manufacturing cost is also higher.
In view of the weak point of above-mentioned magnetizing mediums, the utility model provides a kind of capture rate and separation accuracy to magnetic-particle all higher, little to the ore pulp resistance, the magnetizing mediums that manufacturing cost is lower.
For achieving the above object, a kind of magnetizing mediums provided by the utility model, its structure is that the finer wire surface of circular cross section is provided with many spines and makes.The magnetizing mediums colony that this structure is made is pencil when placing high gradient magnetic separating apparatus, magnetizing field lower magnetic force line when every magnetizing mediums by the original parallel magnetic line of force near the spine summit, with the three-dimensional space direction convergence, thereby near spine, produce very big magnetic field gradient and magnetic field force.It is too near that distance between spine is difficult for, otherwise the magnetic field between spine and spine interferes with each other, and will reduce magnetic field gradient and magnetic field force; Otherwise,, will cause the capture rate of magnetic-particle is reduced if set spine number is very little on Steel Wire Surface, spine is excessive at interval.According to magnetizing medium structure shown in Figure 1, the spine (2) of projection is set on rounded steel wire (1) surface of the section of making by ferrimagnet, the direction of spine is tending towards vertical with the axis of steel wire.Gauge of wire is generally at 0.6～0.8mm, and the height of spine is at 0.10～0.15mm, and the top of spine is sharp more good more.
When the utility model is used for high gradient magnetic separating apparatus according to the magnetizing mediums that said structure provided, produce the bigger magnetic field gradient and magnetic field force except having than existing magnetizing mediums, have little to the ore pulp resistance, as to be difficult for producing magnetizing mediums clogging characteristics, and magnetizing mediums is cleaned easily, changes.When handling weak magnetic mineral, the utility model is roughly the same to the rate of recovery and the existing magnetizing mediums of magnetic product, and the grade of magnetic product improves 1～2 times than original magnetizing mediums; Smart mud productive rate improves 30～40% when handling kaolin.Therefore, the utility model is used for industrial mineral processing, kaolin purification and wastewater treatment etc., have bigger technique effect, and its manufacturing cost is significantly less than existing magnetizing mediums.
One of embodiment that the utility model provides:
According to shown in Figure 1, spine (2) set on steel wire (1) surface is straight line, and steel wire diameter is 0.6mm, and the spine height flat is 0.13mm, and the spine top thickness is 0.03mm, and the spine bottom thickness is 0.1mm, and spine is at interval about 2mm.
Two of the embodiment that the utility model provides:
According to shown in Figure 2, steel wire (3) alternately is provided with spine (4) on the surperficial both sides, and 8～12 spines are set on the steel wire of per 1 centimeter length, and the average height of spine is 0.13mm, and the spine top thickness is 0.03mm, and the thickness of spine bottom is 0.1mm.
Description of drawings:
The general type of the magnetizing mediums that Fig. 1 provides for the utility model;
The magnetizing medium structure schematic diagram that Fig. 2 provides for the utility model embodiment.
Claims (2)
1, be used for a kind of magnetizing mediums that height degree of passing magnetic separating apparatus is used, it is characterized in that on the rounded Steel Wire Surface of the section made by ferrimagnet the sharp perverse of projection being set, the direction of spine is tending towards vertical with the axis of steel wire;
2, according to the described a kind of magnetizing mediums of claim 1, it is characterized in that spine set on the Steel Wire Surface is straight line, steel wire diameter is 0.6mm, the spine average height is 0.13mm, the spine top thickness is 0.03mm, and the spine bottom thickness is 0.1mm, and spine is at interval about 2mm.
