Enkambisweni yokuhlukaniswa kwamagnetic kwe-magnetite, ngenxa ye-magnetic agglomeration, kulula ukukhiqiza "i-magnetic inclusions" kanye "ne-non-magnetic inclusions", ezithinta kakhulu izinga lama-concentrates. Umshini wokuwasha nokugxila we-electromagnetic ozenzakalelayo othuthukiswe ngokuzimela yiWalt uyisizukulwane esisha semishini yokuhlukanisa amandla we-magnetic field ebuthakathaka. Ubheka ngokuphelele amasimu amandla aphelele njengamandla kazibuthe, amandla adonsela phansi, ukubutha, amandla e-centrifugal, njll. Uma kuhlanganiswe, amapharamitha okusebenza alungiswa ngokuzenzakalelayo ngokwezakhiwo ze-ore, okunganciphisa ngempumelelo okuqukethwe kokungcola njenge-silicon, i-phosphorus, ne-sulfur kuma-magnetic ores, futhi kutholakale ama-magnetite concentrates aphezulu kanye nemikhiqizo ephakathi efana nama-concentrates enkambisweni yokuhlukaniswa kwamagnetic, afaneleka kusengaphambili. I-concentrate yokugcina ifanelekela ukusebenza kokuzuza kwe-magnetite concentrator, okuvula indlela entsha yokuthi i-iron concentrator yezwe lami isebenzise isu "lokuthuthukisa nokunciphisa ukungcola".
Isimiso sokusebenza
I-ore ifakwa engxenyeni ephakathi nengaphezulu yomshini wokukhipha amanzi yi-ore feeding hopper kanye nepayipi lokudla i-ore, bese igezwa ngamanzi okuhlanza. Phakathi kwama-coil amabili nalapho i-coil ivuliwe, njengoba amandla kazibuthe ehlayo encishisiwe kakhulu, iyanqunywa futhi isakazwe ukugeleza kwamanzi okuhamba ngesivinini esiphezulu, ukuze i-gangue eyodwa, i-ore slime kanye nezinto eziphilayo ezihlangene zixubane kuyo, ikakhulukazi izinto eziphilayo ezihlangene ezimpofu. Ibhande eligijimayo liphezulu, futhi ngaphansi kwesenzo sokugeleza kwamanzi okuhamba phezulu okunamandla, likhuphukela emaphethelweni okugcwala futhi likhishwe libe yizinsila ezakhiwe kakhulu yimizimba ehambisanayo.
Umgomo wokusebenza komshini wokukhetha i-electromagnetic panning
Amaminerali kazibuthe akule ore adonswa amandla kazibuthe yinsimu kazibuthe ekhiqizwa yi-coil kagesi, kanti izinhlayiya ze-ore kazibuthe ezidonswa amandla ziba yi-dipole kazibuthe, futhi ama-dipole amaningi kazibuthe ayakhangana ukuze akhe amaketanga kazibuthe. Lapho i-coil ivuliwe, ukuxhumana okusheshayo kokuphuma kwamandla kuhlakazeka ngokuphelele ngokucheba kwe-axial ngaphansi kwesenzo sokugeleza kwamanzi okujikelezayo okusheshayo nokukhuphukayo. Inqubo engenhla iyaphindwa lapho i-coil elandelayo inikwa amandla futhi incishiswa amandla. Le nqubo yenziwa izikhathi eziningi, ukuze izinto kazibuthe zikhethwe izikhathi eziningi emshinini wokwenza i-elutriation ukuze kutholakale i-magnetite concentrate yezinga eliphezulu, futhi ngesikhathi esifanayo, okuqukethwe kokungcola okufana ne-SiO2 nakho kuncishisiwe.
Inqubo yokulawula umshini wokuwasha
Umshini wokuhlaziya usebenzisa ukulawula okunezimpembelelo ezimbili, okungukuthi, ukugcwala kokuchichima kanye nokugcwala kokuchichima kuyizinhloso zokulawula. Ukugcwala kokuchichima kulawulwa ubukhulu bamandla kazibuthe, kanti ukugcwala kokuchichima kulawulwa ngokuvuleka kwevalvu engezansi. Ohlelweni lokulawula, ngokubeka amanani okuqondiwe okugcwala kokuchichima kanye nokugcwala kokuchichima, uhlelo lokulawula lusebenzisa i-algorithm yokulawula ehlakaniphile ukulawula amandla kazibuthe kanye nokuvulwa kwevalvu engezansi ukugcina inani lokuqondiwe ngaphakathi kwebanga elithile lokusebenza.
Uma inani lokudla kwe-ore lingazinzile, uhlelo lokulawula luzolungisa ngokuzenzakalelayo i-valve engezansi ngokuya ngokushintsha kokugcwala okungaphansi komshini wokuhlanza, ukuze i-magnetic medium ngaphakathi komshini wokuhlanza ihlale ingashintshi futhi igcine indawo yokuhlunga eqinile; Uma ukuphakelwa kwamanzi kungazinzile, uhlelo lokulawula lulungisa ukuqina kwensimu yamagnetic ngokuya ngokushintsha kokugcwala komshini wokuwasha ukuqinisekisa ukuzinza kwenkomba yokuhlanza.
Umshini wokukhetha nokulungisa we-electromagnetic othomathikhi usebenzisa indlela yokulawula yokwenza ngcono ye-PID ethuthukisiwe, engadingi umsebenzi wesandla futhi esebenza kahle kakhulu. Besebenzisa ubuchwepheshe be-Intanethi Yezinto, amapharamitha okusebenza adluliselwa epulatifomu yamafu ekude, futhi amafayela e-elekthronikhi amiswa ukuze imishini iphathe wonke umjikelezo wokuphila; Ochwepheshe benkampani yethu bokucubungula amaminerali bangalungisa kude amapharamitha okucubungula amaminerali omshini wokuwasha ngepulatifomu yokuqapha ekude ukuze bakhonze kangcono abasebenzisi.
