I-slag yentsimbi, njenge-slag yokugqibela yenkunkuma eveliswa kukunyibilikisa intsimbi, iqulethe izinto zentsimbi ezininzi. Ngenxa yobuninzi bayo kunye nobuninzi bayo obukhulu, ayinakuthandwa kwaye isetyenziswe kushishino lokwakha. Izixhobo zentsimbi ezixabisekileyo azikafunyanwa kakuhle, nto leyo ebangela ukuba kubekho inkunkuma ethile. I-slag yentsimbi kufuneka iphinda isetyenziswe kwaye isetyenziswe kwakhona ngenkqubo ethile yokwahlula imagnethi, kwaye ihlangabezane neemfuno zodidi lwentsimbi yomgubo olufunekayo kwizinto eziqulathe intsimbi zokunyibilikisa i-blast furnace, ukuze i-slag yentsimbi ikwazi ukuphinda isetyenziswe. Ingasetyenziswa ngcono ekwakheni.
Okwangoku, inkqubo ethile yokwahlulahlula i-magnethi yindlela enokwenzeka ngakumbi, kwaye kubalulekile ukukhetha izixhobo ezifanelekileyo ukuze kufezekiswe ukwahlulwa kwentsimbi kunye nokubuyiselwa okusebenzayo. I-slag yentsimbi iyagaywa ukuze iphumeze ukwahlulwa kwayo, kwaye emva koko ngokwahlukana kwe-magnetic okomileyo kwe-powder ore emoyeni, i-feed ore, i-concentrate kunye ne-tailings ziyafunyanwa ngokulandelanayo, kwaye umgangatho wentsimbi iyonke uyahlalutywa kwaye uhlalutywe ukuze kufunyanwe iiparameter zenkqubo kunye nezixhobo ezilungileyo. Nika inkxaso yobugcisa efanelekileyo kwimveliso yokwenyani.
Iipropati ze-slag zentsimbi
I-steel slag yinkunkuma eveliswa kukusetyenziswa kwe-magnesium lime ephezulu, i-active lime kunye nezinye izinto ezincedisayo zokucoca kunye nokuvuthela ioksijini kwinkqubo yokwenza intsimbi, ngoko ke iqulethe i-iron oxide ephezulu, ngokubanzi i-20%-40%, kwaye umxholo we-FeO ungaphezulu kwe-Fe2O3, owokuqala ngokubanzi yi-15%-25%, ngelixa owokugqibela yi-5%-15%, zombini ezibonisa ubunewunewu obubuthathaka.
Izixhobo zovavanyo
Izixhobo zovavanyo zamkela i-FX0665 powder ore air dry magnetic separator yeHuate Company, esetyenziswa kakhulu ekukhetheni i-magnetite ngaphambi kokuba itshiswe okanye ukuvelisa i-concentrate efanelekileyo evela kwi-powdered magnetite.

iqokobhe elisezantsi
Umgaqo wokusebenza we-powder ore air dry magnetic separator uboniswe kumfanekiso. Iiminerali zinikwa kumphezulu we-magnetic drum nge-ore feeding port 3, kwaye iiminerali ze-magnetic zifunxwa kumphezulu we-magnetic drum 4 phantsi kwesenzo samandla e-magnetic, kwaye zijikelezwe nge-magnetic drum 4. Ngexesha lale nkqubo, iiminerali kumphezulu we-magnetic drum 4 ziphantsi kwesenzo esidibeneyo se-magnetic pulsation ye-wrap-angle enkulu kunye nee-multi-pole magnetic poles, isixhobo sokuvuselela i-magnetic, isixhobo sokungena komoya 6 kunye ne-dust removal port 5, ukuze ukungcola kwi-minerals kunye nezinto eziphilayo ezidibeneyo ezihlwempuzekileyo kususwe ngokufanelekileyo. Ngaloo ndlela, umgangatho we-concentrate uyaphucuka. Emva kokuba iiminerali ezikhethiweyo zijikeleziswe kwindawo engeyiyo i-magnetic nge-magnetic drum 4, zityetyiswa kwi-concentrate port 9 phantsi kwesenzo somxhuzulane, amandla e-centrifugal kunye nesixhobo sokukhulula ukuze zibe yi-concentrate. Iiminerali ezingezizo imagnethi okanye imizimba edibeneyo ethambileyo ayifakwanga emlonyeni we-tailings phantsi kwesenzo somxhuzulane kunye namandla e-centrifugal, kwaye iba yi-tailings okanye i-ore ephakathi.
Ubuchule kunye netekhnoloji ephambili yokwahlulahlula i-powder ore emoyeni owomileyo wemagnethi
1. I-feeder edlidlizayo isetyenziselwa ukondla, kwaye iiparameter ze-feeder zinokulungiswa ukuze kufunyanwe ukondla okufanayo;
2. Inkqubo yemagnethi isebenzisa uyilo lwe-multi-pole, i-angle enkulu yokusonga (ukuya kuthi ga kwi-200-260 degrees), amandla aphezulu entsimi (3000-6000Gs), kwaye ulwakhiwo lwenkqubo yemagnethi lungatshintshwa ngokweempawu zezimbiwa ukuze kufezekiswe izalathisi ezifanelekileyo zokuphucula;
3. Isantya esithe ngqo sesilinda sihlengahlengiswa ngaphakathi kwe-1-20m/s, kwaye isantya esithe ngqo esifanelekileyo singakhethwa ngokwendalo yentsimbi; isilinda senziwe ngezinto ezingezizo ezesinyithi kwaye sixhotyiswe ngesixhobo sokuxuba esinemagnethi ukuphucula umgangatho wokugxila;
4. Inesakhiwo esithile semela yomoya, isixhobo sokubuyisela umoya kunye nesixhobo sokususa uthuli (iiparameter ezifanelekileyo zingakhethwa ngokwendalo kunye neemfuno zesalathisi se-ore); umphezulu wesilinda unikwe isixhobo sokukhulula, esinokukhupha umxube ococekileyo;
I-FX powder ore air dry magnetic separator ikakhulu yenziwe sisixhobo sokudlulisa, idrama yokwahlula imagnethi, isixhobo sokuvuthela, isixhobo sokususa uthuli oluyi-induction, isixhobo sokuqokelela i-sedimentation, njl. Amandla e-magnetic field edrama yokwahlula imagnethi yi-3500Gs. , amandla emagnethi, amandla e-centrifugal ajikelezayo, njl., inokufikelela ekukhetheni kwangaphambili okomileyo kwe-0-5mm particle size magnetite okanye iphucule kakhulu umgangatho we-fine powder magnetite. Iziphumo eziphambili zezi zilandelayo:
A. Udidi olukhethiweyo lwe-0-5mm magnetite lunokwandiswa ukusuka kwi-10% ukuya ngaphezulu kwe-40%. Lungasetyenziswa njengokulahla ngaphambi kokuba lugaywe, nto leyo enokuphucula kakhulu umgangatho wokungena kwaye iphucule ukusebenza kakuhle kwesixhobo sokugaya.
B. Udidi olukhethiweyo lwe-magnetite ecolekileyo ye--74um kunye ne--45um lunokwandiswa ukusuka kwi-10% ukuya ngaphezulu kwe-60%, kwaye i-concentrate efanelekileyo ingafunyanwa ngokuthe ngqo ngokukhetha okomileyo.
