Enqubweni yokuhlukaniswa kazibuthe kwe-magnetite, ngenxa ye-agglomeration kazibuthe, kulula ukukhiqiza "i-magnetic inclusions" kanye "ne-non-magnetic inclusions", okuthinta kakhulu izinga lokugxila. I-Walt iyisizukulwane esisha semishini yokuhlukanisa kazibuthe ebuthakathaka.Icubungula ngokuningiliziwe izinkambu zamandla abanzi njengamandla kazibuthe, amandla adonsela phansi, i-buoyancy, amandla e-centrifugal, njll. Kuhlanganiswe, imingcele yokusebenza ilungiswa ngokuzenzakalelayo ngokuvumelana nezakhiwo ze-ore, ezinganciphisa ngempumelelo okuqukethwe kokungcola okufana ne-silicon, i-phosphorus. , kanye nesibabule ku-ores kazibuthe, futhi uthole i-high-grade magnetite igxilisa kanye nemikhiqizo ephakathi efana nokugxila enqubweni yokuhlukanisa kazibuthe, efanelekile kusengaphambili.I-concentrate yokugcina ifanele ukusebenza kokusizakala kwe-concentrator kazibuthe, okuvula indlela entsha yokugxilisa insimbi yezwe lami ukuze kuqaliswe isu “lokwenza ngcono kanye nokunciphisa ukungcola”.
Isimiso sokusebenza
Insimbi idlelwa engxenyeni ephakathi nendawo engenhla yomshini wokukhipha insimbi ngensimbi yokuphakela insimbi kanye nepayipi lokuphakela insimbi, futhi ikhukhulwe ngamanzi acwengayo.Phakathi kwamakhoyili amabili nalapho ikhoyili icishwa, njengoba amandla kazibuthe ashona phansi ebuthakathaka kakhulu, ayagundwa futhi ahlakazwe ukugeleza kwamanzi ajikelezayo phezulu ngesivinini esikhulu, ukuze i-ganggue eyodwa, i-ore slime kanye nezinto eziphilayo ezihlangene zixubane kuwo. , ikakhulukazi izinto eziphilayo ezimpofu ezihlangene.Ibhande eligijimayo liphezulu, futhi ngaphansi kwesenzo sokugeleza kwamanzi azungezayo anamandla amakhulu uma kuqhathaniswa, akhuphukela onqenqemeni oluchichimayo futhi akhishwe ukuze abe imisila ikakhulukazi eyakhiwe imizimba ehlangene.
Umgomo wokusebenza womshini wokukhetha i-electromagnetic panning
Amaminerali kazibuthe ku-ore adonswa amandla kazibuthe akhiqizwa ikhoyili kagesi, futhi izinhlayiya zensimbi kazibuthe ziphenduka ama-dipoles kazibuthe, futhi ama-dipoles kazibuthe amaningi adonselana ukuze akhe amaketanga kazibuthe.Lapho ikhoyili icinywa, ukugeleza okuzenzakalelayo ukuxhunyaniswa kokucisha kwamandla kuhlakazwa ngokugcwele ukugunda kwe-axial ngaphansi kwesenzo sokugeleza kwamanzi ajikelezayo ngesivinini esikhulu futhi akhuphukayo.Inqubo engenhla iyaphindwa lapho ikhoyili elandelayo inikwa amandla futhi iphelelwa amandla.Le nqubo yenziwa izikhathi eziningi, ukuze izinto kazibuthe zingakhethwa izikhathi eziningi emshinini we-elutriation ukuze kutholwe i-high-grade magnetite concentrate, futhi ngesikhathi esifanayo, okuqukethwe kokungcola okufana ne-SiO2 nakho kuyancipha.
Inqubo yokulawula yomshini wokuwasha
Umshini we-elutriation usebenzisa ukulawulwa kwe-impulse emibili, okungukuthi, ukugxila kokuchichima kanye nokugxila kokugeleza okungaphansi kuyizinjongo zokulawula.Ukugxiliswa kokuchichima kulawulwa ubukhulu bamandla kazibuthe, futhi ukugxiliswa kokugeleza kulawulwa ngokuvula phansi. I-valve.Kusistimu yokulawula, ngokusetha amanani okuhlosiwe okugxiliswa kokuchichima nokugxilisa ukugcwala kwamanzi, isistimu yokulawula isebenzisa i-algorithm yokulawula ehlakaniphile ukuze ilawule amandla kazibuthe kanye nokuvulwa kwe-valve engezansi ukuze kugcinwe inani eliqondiwe ngaphakathi kwebanga elithile lokusebenza. .
Uma inani lokuphakela ngensimbi lingazinzile, isistimu yokulawula izolungisa ngokuzenzakalelayo i-valve engezansi ngokuvumelana noshintsho lokuhlushwa kwamanzi angaphansi kwamanzi ngaphakathi komshini we-elutriation, ukuze i-magnetic medium ngaphakathi komshini we-elitriation ihlale ingashintshile futhi igcine indawo yokuhlunga ezinzile; ukunikezwa kwamanzi akuzinzile, uhlelo lokulawula lulungisa ukuqina kwamandla kazibuthe ngokusho kokushintsha kokuhlushwa okuchichimayo komshini wokuwasha ukuze kuqinisekiswe ukuzinza kwenkomba yokugxila.
Umshini ozenzakalelayo wokuphena kanye nokukhetha kuka-electromagnetic wamukela indlela yokulawula ethuthukisiwe ye-PID-othomathikhi, engadingi umsebenzi owenziwa ngesandla futhi ehlala isebenza esimweni esihle kakhulu. Ngokusebenzisa ubuchwepheshe be-inthanethi Yezinto, imingcele yokusebenza idluliselwa endaweni yesikhulumi samafu esikude, kanye ne-elekthronikhi. amafayela asungulelwa okokusebenza ukuze alawule umjikelezo wokuphila wonke;Ochwepheshe bokucubungula amaminerali enkampani yethu bangakwazi ukulungisa bekude imingcele yokucubungula amaminerali omshini wokuwasha ngokusebenzisa isiteji sokuqapha esikude ukuze bakhonze kangcono abasebenzisi.
