I-Slag yensimbi, njenge-slag yokugqibela ekhutshwe yi-smelting yensimbi, iqulethe izinto eziphezulu zentsimbi.Ngenxa yoxinaniso oluphezulu kunye nokuxinana kwesambuku esikhulu, ayinakudunyiswa kwaye isetyenziswe kushishino lokwakha.Ubuncwane obuxabisekileyo bentsimbi abukafunyanwa kakuhle, okubangele umlinganiselo othile wenkunkuma.I-slag yensimbi kufuneka ihlaziywe kwaye isetyenziswe kwakhona ngenkqubo ethile yokwahlukana kwamagnetic, kwaye ihlangabezane neemfuno zomgangatho wentsimbi ye-powder efunwa yi-iron-containing material for blast furnace smelting, ukwenzela ukuba i-slag yensimbi ingaphinda isetyenziswe.Inokusetyenziswa ngcono kulwakhiwo.
Okwangoku, inkqubo ethile yokwahlukana kwamagnetic yindlela enokwenzeka ngakumbi, kwaye kunyanzelekile ukuba ukhethe izixhobo ezifanelekileyo ukufezekisa ukwahlukana kwentsimbi kunye nokubuyisela ngokufanelekileyo.I-slag yentsimbi iphantsi ukuze iqonde ukuhlukana kwayo, kwaye emva koko ngomoya owomileyo wokwahlukana kwemagnethi ye-powder ore, i-ore yokutya, i-concentrate kunye ne-tailings ifunyenwe ngokulandelelana, kwaye ibakala lentsimbi lilonke liyahlalutywa kwaye lihlalutywe ukufumana eyona nkqubo kunye nezixhobo. iiparamitha.Ukubonelela ngenkxaso yobugcisa efanelekileyo kwimveliso yokwenene.
Iipropati ze-Slag zensimbi
I-Slag yensimbi yinkunkuma eveliswa ngokusetyenziswa kwekalika ephezulu ye-magnesium, ikalika esebenzayo kunye nezinye izinto ezincedisayo zokucoca kunye neoksijini evuthela kwinkqubo yokwenza intsimbi, ngoko iqulethe i-iron oxide ephezulu, ngokubanzi i-20% -40%, kunye nomxholo we-FeO. ingaphezulu Fe2O3 , yangaphambili ngokuqhelekileyo i-15% -25%, ngelixa i-5% -15%, zombini ibonisa i-magnetism ebuthathaka.
Izixhobo zovavanyo
Isixhobo sovavanyo samkela i-FX0665 powder ore air dry magnetic separator ye-Huate Company, esetyenziswa kakhulu ekukhethweni kwangaphambili kwemagnetite ngaphambi kokusila okanye ukuveliswa kokugxila okufanelekileyo kwi-magnetite engumgubo.

iqokobhe elisezantsi
Umgaqo osebenzayo wepowder ore air dry separator umazibuthe uboniswa kumzobo.Iiminerali zondliwa kumphezulu wegubu lamagnetic ngokusebenzisa i-ore feed port 3, kwaye iiminerali zemagneti zibhengezwa kumphezulu wegubu lamagnetic 4 phantsi kwesenzo samandla kazibuthe, kwaye zijikeleze ngegubu lamagnetic 4. Ngeli xesha loku. Inkqubo, iiminerali kumphezulu wegubu kazibuthe 4 ziphantsi kwesenzo esidityanisiweyo sokutyhalwa kwamagnetic kwikona enkulu yokusonga kunye neepali ezininzi zemagnethi, isixhobo sokuvuselela imagnethi, isixhobo sokungenisa umoya 6 kunye nezibuko lokususa uthuli. 5, ukwenzela ukuba ukungcola kwiiminerali kunye nezinto eziphilayo ezidibeneyo ezihluphekileyo zipheliswe ngokufanelekileyo.Ngaloo ndlela, ibakala lokugxila liyaphuculwa.Emva kokuba iiminerali ezikhethiweyo zijikelezwe kwindawo engeyiyo i-magnetic kunye ne-drum magnetic 4, zixutywe kwi-concentrate port 9 phantsi kwesenzo sobunzima, amandla e-centrifugal kunye nesixhobo sokukhulula ukuba sigxininise.Iiminerali ezingezizo ezezibuthe okanye imizimba ebhityileyo edibeneyo ayibandakanywanga emlonyeni wentsalela yesi-8 phantsi kwentshukumo yomxhuzulane kunye namandla aphakathi, kwaye ibe ziintsila okanye intsimbi ekrwada ephakathi.
Ukwenziwa kwezinto ezintsha kunye nethekhinoloji ephambili yepowder ore air dry separator
I-1.I-feeder vibrating isetyenziselwa ukutya, kwaye iiparameters ze-feeder ziyakwazi ukulungelelaniswa ukufezekisa ukutya okufanayo;
I-2.Inkqubo yamagnetic ithatha i-multi-pole, i-angle enkulu yokugoqa (ukuya kwi-200-260 degrees), amandla omhlaba aphezulu (3000-6000Gs) uyilo, kunye nokwakheka kwenkqubo yamagnetic kunokutshintshwa ngokweempawu zeminerali ukufezekisa izikhombisi ezifanelekileyo zokuxhamla. ;
3.Isantya somgca we-cylinder sihlengahlengiswa ngaphakathi kwe-1-20m / s, kwaye isantya esifanelekileyo somgca sinokukhethwa ngokohlobo lwe-ore;i-cylinder yenziwe ngezinto ezingezona zetsimbi kwaye ixhotyiswe ngesixhobo sokuvuselela magnetic ukuphucula ibakala lokugxila;
