Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the schematic diagram of preferred embodiment of the present invention flow process; And
Fig. 2 is preferred embodiment of the present invention separation equipment schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The invention provides a kind of feldspar ore impurity-removing method, the method is for separating of the quartz in feldspar ore and iron content and/or titanium mineral impurity.Adopt the method to be separated, the separation difficulty problem caused because quartz grain surface texture is similar to feldspar can be avoided.Improve separation accuracy and the degree of accuracy.
There is black or the yellow impurities of bigger difference with feldspar color in iron content and/or titanium mineral impurity herein.As kaolin.
See Fig. 1, method provided by the invention comprises the following steps:
1) classification process is carried out to feldspar ore, obtain the breaking ores that granularity is 1 ~ 50mm; 2) breaking ores falls into conveying device, makes breaking ores separated from one another, and light source irradiation breaking ores produces optical signal, and optical signals CCD (charge coupled cell) camera is collected; 3) optical signal is converted to the signal of telecommunication by converter by CCD camera, to control separator, is separated by impurity with breaking ores.
First method provided by the invention needs to carry out break process to feldspar ore.Handled feldspar ore can be raw ore, and preferred the method is suitable for process potassium oxide content <8%, the feldspar ore of sodium oxide content <84%.In this type of feldspar ore, quartz content is higher, and quartz and feldspar density, hardness are closely, and surface nature is also more similar.And although the floatation having this mutually isostructural mineral employing conventional can be separated, need through repeatedly flotation, or repeatedly reverse flotation could realize, and in flotation, need to use all kinds of flotation agent, add production cost.For the ease of subsequent hierarchical process, break process can be carried out to feldspar ore.The program of break process can be selected according to the particle diameter of pending feldspar ore.A kind of or wherein any number of combination in preferred employing jaw crusher, kibbler roll, impact crusher or gyratory crusher.Now crushing efficiency is higher, can enhance productivity.Be more preferably sequentially through No. 2 jaw crushers, 1 pair roller breaks or after No. 1 jaw crusher, 1 hammer crushing function obtains the mineral that particle size range is 2 ~ 6mm faster.
Be more preferably in the present invention and find when the particle diameter of handled breaking ores 110 is 2 ~ 6mm, the adhesive ability of impurity to breaking ores 110 is lower, can reduce the impurity level of breaking ores 110 surface attachment, reduces the misuse rate caused when being separated ore and impurity.Separative efficiency is made to reach the highest.The identification capability of CCD camera to the impurity material be attached on this particle diameter ore reaches the highest.Thus reach the highest identification efficiency, improve magazins' layout rate.Preferred, when the particle diameter of breaking ores 110 is 2 ~ 3mm, after first separation, the potassium oxide content >9% in gained breaking ores 110, sodium oxide content >2%.Certainly because feldspar ore kind is more, found through experiments when the method is 1 ~ 50mm or 2 ~ 40mm for the treatment of particle diameter and still can serve the same role.
The feldspar ore of a large amount of 2 ~ 6mm is there is in ore after this fragmentation.In order to improve later separation efficiency, also needing to carry out classification process to breaking ores 110, the breaking ores 110 of 2 ~ 6mm in breaking ores 110 being selected, enters in the hopper 100 in equipment as shown in Figure 2.Breaking ores 110 falls under gravity in conveying device 200200 after entering hopper 100.Breaking ores 110 is under the effect of conveying device 200, and ore particles is wherein separated from one another, and keeps certain distance.After conveying device 200, breaking ores 110 be thrown into be oppositely arranged between the first CCD camera 310 and the second CCD camera 320.Now the exposed surface of the overwhelming majority of ore particles can be irradiated to by light source 300, and produces corresponding optical signal.Light source 300 used herein can be a kind of or wherein any number of combination in fluorescent lamp, LED, X-ray or microwave.Can select according to the impurity on handled feldspar, if feldspar and impurity color distinction are enough large, preferred fluorescent lamp, otherwise the light source that need use other.
The optical signal now produced fully is accepted by the first CCD camera 310 and the second CCD camera 320, thus obtains more complete optical signal.Converter 400 afterwards in the first CCD camera 310 and the second CCD camera 320 is as DSP signal processor, and optical signal is converted to the signal of telecommunication by FPGA processor, by electric signal transmission to separator 500, is separated by impurity with breaking ores 110.Breaking ores 110 through removal of impurities is put in finished bin 800.The impurity particle be separated drops in impurity storehouse 700 under the effect of separator 500.Thus impurity and feldspar ore are separated.Separator 500 herein can be pulse jet or mechanical arm.Be preferably pulse jet, the impurity being attached to mineral surface can be sprayed by pulse jet and leave ore, thus removing, can separative efficiency be improved.
The present invention additionally provides a kind of feldspar ore obtained as stated above on the other hand, the potassium oxide content >9% of feldspar ore, sodium oxide content >2% after being separated.
See Fig. 2, the present invention additionally provides a kind of equipment for the method on the other hand, comprise conveying device 200, for carrying and the first CCD camera 310 and the second CCD camera 320 shaking loose breaking ores, be oppositely arranged, for obtaining optical signal, the converter 400 of breaking ores, for optical signal being converted to the signal of telecommunication and separator 500, breaking ores 110 performs lock out operation, and the first CCD camera 310 and the second CCD camera 320 are arranged at the discharging opening of conveying device 200; Converter 400 is connected with the second CCD camera 320 with the first CCD camera 310 simultaneously; Separator 500 is connected with converter 400.Adopt this device to carry out removal of impurities to breaking ores 110, the impurity portion on breaking ores 110 surface is shaken off by the vibrational energy that first conveying device 200 produces.Breaking ores 110 after conveying device 200 is through the first CCD camera 310 and the second CCD camera 320, impurity and breaking ores 110 can be made to be subject to the irradiation of light source 300 respectively, thus producing different optical signals, optical signal is converted to the signal of telecommunication by converter 400.The signal of telecommunication is compared with the signal of telecommunication preset, when being different from the default feldspar signal of telecommunication, the signal of telecommunication is converted to instruction, controls separator 500 and carries out lock out operation to the breaking ores producing this optical signal, make it fall into impurity storehouse 700, thus separate with breaking ores 110.
