Abstract
The utility model relates to the technical field of mineral separation equipment, in particular to a combined deslagging screen used for a magnetic separator. The deslagging screen comprises a rack, a cylinder screen arranged on the rack, a slag receiving bucket arranged on the rack, a slag discharging water pipe, a slagging groove arranged below the slag receiving bucket and a driving device and is characterized in that the end part of the slagging groove and the upper part of an undersize mineral receiving pipe are provided with a flat screen; and the flat screen together with the cylinder screen constitutes the combined deslagging screen. The mesh size of the flat screen is 1.2-1.4mm. The combined deslagging screen is characterized in that: on the basis of a cylinder deslagging screen, the end part of the slagging groove is added with the flat screen so as to fully recover the iron-bearing mineral (fine particle) in the oversize material of the deslagging screen, reduce the TFe grade of tailings of a strong magnetic separator by 0.1% and decrease metal loss.
Description
Technical field
The utility model relates to the preparation equipment technical field, and particularly a kind of magnetic separator removes ballast screen with combination.
Background technology
In the lean hematite ore dressing process, used beneficiation flowsheet mostly is weight-magnetic-floating combined mineral dressing technology flow process at present.Because vertical ring high-gradient magnetic separator is good to low intensity magnetic separation mineral recovering effect, rate of recovery height, fault rate is low, and working stability is so the middle magnetic in the technology, strong magnetic are used vertical ring high-gradient magnetic separator more.In production application, the cartridge of vertical ring high-gradient magnetic separator recovery weak magnetic mineral is blocked easily, establishes cylinder usually before middle magnetic machine, strong magnetic machine and removes ballast screen, removes the slag in the selected ore pulp in advance.Because the bigger slag of volume can not be trapped in the drum sieve by screen cloth in the ore pulp, in the drum sieve rotation process, be brought to the drum sieve top, drop in the dreg-accepting hopper, after the dreg-accepting hopper groove face that tilts flows to ash pit, be discharged in the magnetic separator mine tailing in self gravitation and the impact of unloading pulp water.Have a part of iron mineral in these slags of discharging, cause strong magnetic tail ore deposit TFe grade higher, this part grade runs off in vain at the metal of 15-18%.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and the magnetic separator that can reduce metal loss removes ballast screen with combination.
The purpose of this utility model realizes by following technical proposals:
A kind of magnetic separator of the present utility model removes ballast screen with combination, comprise frame, be located at drum sieve on this frame, be located at dreg-accepting hopper, slag dumping water pipe on the described frame, be located at the ash pit and the transmission device of dreg-accepting hopper below, it is characterized in that connecing under the end, sieve at described ash pit pipe above be provided with flat screen, this flat screen is formed combination with described drum sieve and is removed ballast screen.
The mesh size of described flat screen is 1.2-1.4mm.
Characteristics of the present utility model are: remove on the basis of ballast screen at cylinder, added flat screen in the end of ash pit, fully reclaim the iron-bearing mineral (particulate) that removes in the ballast screen oversize, make strong magnetic tail ore deposit TFe grade reduce by 0.1%, reduce metal loss.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, a kind of magnetic separator of the present utility model removes ballast screen with combination, comprise frame 5, be located at drum sieve 4 on this frame 5, be located at dreg-accepting hopper, slag dumping water pipe on the described frame, be located at the ash pit 3 and the transmission device of dreg-accepting hopper below, it is characterized in that connecing under the end, sieve at described ash pit 3 pipe 2 above be provided with flat screen 1, this flat screen 1 is formed combination with described drum sieve 4 and is removed ballast screen.
The mesh size of described flat screen 1 is 1.2-1.4mm, and foreign material on the flat screen, clinker are abandoned with strong magnetic tail ore deposit, reclaims and sieve iron-bearing mineral (particulate) to enter strong magnetic.
Selected ore pulp is through behind the drum sieve 4, its oversize is foreign material, slag, iron-bearing mineral (particulate), under the impact of unloading pulp water, fall in the dreg-accepting hopper, flow to ash pit along the dreg-accepting hopper groove face that tilts, connect pipe 2 and enter strong magnetic and reclaim through sieving down through flat screen 1 its iron-bearing minerals of back (particulate) of ash pit 3 ends.Make strong magnetic tail ore deposit TFe grade reduce by 0.1%, reduce metal loss.
Claims (2)
1. a magnetic separator removes ballast screen with combination, comprise frame, be located at drum sieve on this frame, be located at dreg-accepting hopper, slag dumping water pipe on the described frame, be located at the ash pit and the transmission device of dreg-accepting hopper below, it is characterized in that connecing under the end, sieve at described ash pit pipe above be provided with flat screen, this flat screen is formed combination with described drum sieve and is removed ballast screen.
2. magnetic separator according to claim 1 removes ballast screen with combination, and the mesh size that it is characterized in that described flat screen is 1.2-1.4mm.
