Abstract
The utility model relates to a magnetic dressing device, particularly a magnetic dressing column for magnetic iron ore dressing, which aims to solve the problem that magnetic substances and non-magnetic substances are mixed because of the generation of magnetic coagulations in the magnetic dressing process. The magnetic system in the magnetic dressing column is composed of a control power source and an exciting winding. Through the improvement on the magnetic system, under the same conditions, the concentrate grade is increased by 4-8% on average, and under the same raw ore and the same concentrate grade, the tailing grade, the concentrate grade and the poor tailing grade are reduced by 5-9% on average. The magnetic dressing column can ensure that the concentrate grade of the magnetic iron ore can reach 67-70%, and even super pure iron ore concentrate can be produced. By using the utility model, the productive rate of work can reach 65-90%, and the recovery rate of work can reach between 65% and 90%. Compared with similar devices, the productive rate and the recovery rate of the utility model are both in a high level.
Description
The utility model relates to a kind of magnetic plant, particularly a kind of magnetic separation post that is used for Benefication of magnetite.
Magnetite separation factory magnetic plant commonly used has " magnetic force sloughing-off tank " and " magnetic accumulating machine " now.The core one magnetic system of these two kinds of equipment all adopts the ferrite permanent magnet material.Sloughing-off tank is made turriform to magnetic system, and magnetic accumulating machine is made the multi-turn layer to magnetic system and disperseed shape.The purpose of alteration of form is that the magnetic coagulation that produces when making ore particle be is necessarily disperseed through magnetic, and deperming is mingled with, tells intergrowth with non magnetic, thereby improves concentrate grade.But because they are stationary magnetic fields, no matter how pole form changes, still in various degree existence of magnetic coagulation, and magnetic and the non magnetic problem that is mingled with can not get basic solution.Therefore concentrate grade is difficult to improve, and generally can only reach 61～64%.
The utility model is changed the conventional structure of magnetic plant magnetic system in the past.Designed the controllable electromagnetism magnetic plant in magnetic field-magnetic separation post in a kind of magnetic system.Solve the magnetic coagulation that produces when ore particle through magnetic is and the magnetic of bringing, the non magnetic problem that is mingled with, significantly improve concentrate grade.
The utility model is to realize like this; The magnetic separation post comprises mine feeding bucket, overflow launder, upper support pin, cylinder, magnetic system, feed pipe, pucking, lower support pin, concentrate ore discharge pipe and control valve, it is characterized in that: magnetic system is made of control power supply and magnet exciting coil.The control power supply can be that the cydariform power supply adds the current switching device formation that gate-controlled switch is formed, and excitation electricity circle can be six to eight, vertically arranges.The connected mode of magnet exciting coil can be a serial or parallel connection.For the architectural feature of magnetic separation post more can be described, its course of work is summarized as follows: the raw ore that is made of monomer magnetic iron ore, gangue and intergrowth enters the magnetic separation post from mine feeding bucket through mineral-feeding pipe, under the energising magnet exciting coil produces in magnetic system the continuous downward magnetic force and gravity effect own, magnetite ore particles, the downward sedimentation of intergrowth.Be subjected to tangentially feeding the impulse force of the current of rotation rising again from feed pipe.By control power supply control magnet exciting coil variation magnetic field polarity and magnetic field intensity, make the magnet ore particle repeatedly reunite, disperse.Discharge high grade iron concentrate by pucking bottom ore discharge pipe at last.Gangue and intergrowth are discharged from overflow launder under the ascending current effect.
The utility model is compared with the most close magnetic plant, by the effective processing to the magnetic coagulation problem, is giving the ore deposit grade close, and under the close situation of tailings grade, concentrate grade can improve 4.0～8.0%.If make concentrate grade close, tailings grade just can hang down 5～9% so.It is effectively to tell intergrowth from various conventional magnetic plant magnetic separation rocks ore deposit that the choosing of magnetic separation post divides main feature.Thereby can make the magnetite concentrate grade reach 67～70%, even can produce ultrapure iron concentrate.The utility model operation productive rate reaches 65～90%, and operation recovery is the higher level of close equipment between 65～93%.
Accompanying drawing is the structure chart of magnetic separation post.
The utility model is described in detail by embodiment below in conjunction with accompanying drawing, but the utility model is not limited to this example.
The magnetic separation post is made of following part: mine feeding bucket (1), overflow launder (2), upper support pin (3), cylinder (4), all adopt nonmagnetic substance to make, as non-magnetic stainless steel.The cydariform power supply that magnetic system (5) power supply is produced with mine, Tianjin instrument plant adds the current switching device formation that gate-controlled switch is formed.Six of magnet exciting coils are vertically arranged.From top to bottom coil 1 and 4,2 and 5,3 is connected with 6.Feed pipe (6) tangentially feeds, and water enters the back and risen by magnetic separation column bottom Rotating with Uniform.Pucking (7), lower support pin (8), concentrate ore discharge pipe and control valve (9).
Claims (3)
1, a kind of magnetic plant, particularly a kind of magnetic separation post that is used for Benefication of magnetite, it comprises mine feeding bucket (1), overflow launder (2), upper support pin (3), cylinder (4), magnetic system (5), feed pipe (6), pucking (7), lower support pin (8), concentrate ore discharge pipe and control valve (9), it is characterized in that, magnetic system (5) is made of control power supply and magnet exciting coil.
2, magnetic separation post according to claim 1 is characterized in that: the control power supply in the magnetic system (5) can be that the cydariform power supply adds the current switching device formation that gate-controlled switch is formed, and magnet exciting coil can be six to eight, vertically arranges.
