Njengoba izwe libheka ukubaluleka kokuvikelwa kwemvelo, njengohlobo lwemfucuza eqinile, indlela yokusebenzisa i-slag yensimbi isibe yisihloko esibalulekile. Lesi sihloko sethula ikhambi lobuchwepheshe eliphelele lokuvuselela i-slag yensimbi. Ubuchwepheshe bokucubungula okomile kumele buqinisekise ukubuyiswa okuphumelelayo kwezinsimbi ngakolunye uhlangothi kanye nokusetshenziswa okugcwele kwezinsalela zemfucuza kolunye. Izinyathelo ezilandelayo zokucubungula i-slag yensimbi zichazwe: Ukuchoboza okukhethayo; ukuhlukaniswa kwamagnetic kanye nendima yomshini omusha we-roller osebenzisa umfutho ophezulu we-single-drive ekusetshenzisweni okugcwele kwe-slag yensimbi; ukusetshenziswa kwemishini emisha kunganciphisa kakhulu izindleko zokuchoboza i-slag yensimbi, ngaleyo ndlela kudale izinzuzo ezengeziwe zokusetshenziswa kwe-slag yensimbi. Ukukhuthazwa kokusetshenziswa okugcwele kwe-slag yensimbi kudale ithuba. Ukukhuthazwa kwalomqondo obanzi embonini kudinga imizamo ehlangene yezinkampani zokukhiqiza insimbi, ochwepheshe bokucubungula izimbiwa kanye nezazi, ukusetshenziswa okuphelele kwesicelo, kanye neminyango yokumaketha nokukhuthaza.
Ukusetshenziswa kwe-slag yensimbi ekwakheni
1) I-slag yensimbi isetshenziselwa ukukhiqiza usimende kanye nezingxube zekhonkrithi. I-slag yensimbi iqukethe amaminerali asebenzayo njenge-triccalcium silicate (C3S), i-dicalcium silicate (C2S) kanye ne-iron aluminate enezakhiwo zokusimisa nge-hydraulic, ezihambisana nezici zesimende. Ngakho-ke, ingasetshenziswa njengezinto zokusetshenziswa kanye nengxube yesimende ekukhiqizeni usimende ongeyona i-clinker, i-clinker cement encane. I-slag yensimbi inezimpawu ezinhle kakhulu njengokumelana nokuguguleka, amandla aphezulu okugoba, ukumelana nokugqwala kanye nokumelana nesithwathwa.
2) I-slag yensimbi ithatha indawo yetshe elichotshoziwe kanye ne-aggregate encane. Itshe elichotshoziwe le-slag yensimbi linezinzuzo zokuba namandla aphezulu, indawo elukhuni, ukumelana nokuguguleka okuhle nokuqina, ivolumu enkulu, ukuzinza okuhle, kanye nokuhlanganiswa okuqinile ne-asphalt. Uma kuqhathaniswa netshe elichotshoziwe elivamile, liphinde limelane nezici zokuqhekeka kwezinga lokushisa eliphansi, ngakho-ke lingasetshenziswa kabanzi ekugcwaliseni kabusha kobunjiniyela bemigwaqo. I-slag yensimbi, njenge-ballast yesitimela, inezimpawu zokungaphazamisi umsebenzi wezokuxhumana wesistimu yesitimela kanye nokuqhuba kahle kukagesi. Ngenxa yokuthi i-slag yensimbi inokungena kwamanzi okuhle kanye nokugeleza kwamanzi, izingxenye ezifaka usimende kuyo zingenza iqine ibe yizicucu ezinkulu. I-slag yensimbi ifaneleka futhi ekwakhiweni kwemigwaqo emaxhaphozini nasemabhishi.
Njengamanje, indlela evame kakhulu yokusebenzisa i-slag yensimbi yasekhaya ukuchoboza i-slag yensimbi ibe yi--5mm ukuze ithathe indawo yesihlabathi somfula njengento yokwakha, noma ukugaya i-slag yensimbi echotshoziwe ibe yimpuphu ecolekileyo ukuze isetshenziswe njengesithako sikasimende. I-Shandong Huate Magnetoelectric Technology Co., Ltd. iphinde yenza ucwaningo olujulile ngokusetshenziswa okuphelele kwe-slag yensimbi, yasebenzisa ngobuhlakani i-roller mill ene-drive eyodwa ekuchotshozweni okuhle kwe-slag yensimbi, yathuthukisa ubuchwepheshe bokucubungula i-slag yensimbi, futhi yathola izinzuzo ezinhle kwezomnotho. Isetshenziswe ngempumelelo ePangang Mining kanye nasebhizinisini elithile le-slag yensimbi eLianyungang.
Inqubo yokukhiqiza yendabuko ye-slag yensimbi imi kanje:
1) Izingcezu ezinkulu zichotshozwa nge-jaw crusher kuya ku--50, bese i-magnetic ihlukaniswa nge-pulley yamagnetic.
2) Setha usayizi wokuhlukaniswa kwensimbi ube yi-+45 mm. Ama-0-45 mm asele avame ukusetshenziswa njengokwakhiwa komgwaqo nezinto zokugcwalisa. Ukuze kwandiswe inani lokusetshenziswa kwayo, i-slag yensimbi ingahlukaniswa ibe yi-0-4, 4-8 kanye namanye amamaki ahlukene. Ubuchwepheshe budinga imali encane kanye nezindleko zokusebenza eziphansi. Kodwa-ke, okuqukethwe kwensimbi okungaphezu kuka-50% ku-slag kugxile emandleni angu--10 mm, ngakho-ke lobu buchwepheshe buzobangela ukulahlekelwa okukhulu kwensimbi, kodwa okuqukethwe kwensimbi esindayo kuzokwanda.
Ngakho-ke, ukugaya okumanzi okuthambile kuye kwasetshenziswa kabanzi ikakhulukazi kwi-slag ekhiqizwa ekukhiqizweni kwensimbi ene-alloy ephezulu equkethe i-Cr, i-Ni, i-Mo, njll. Izinqubo ezijwayelekile zifaka phakathi ukuchoboza nokugaya okunezinyathelo ezimbili (i-rod mill/ball mill). Njengoba insimbi enokunwebeka ilula ukuyigaya, ukuhlukaniswa kwe-slag yensimbi nensimbi kungatholakala ngokusikeka noma ukuhlukaniswa. Ubukhulu bengxenye yamaminerali ye-slag buvame ukuba ngaphezu kuka-95% nangaphansi kuka-0.2mm. Izinga lokubuyisa insimbi lale nqubo lidlula u-95%, kanti isivuno sokugxila kwensimbi esikhiqizwayo singama-90 kuya ku-92%. Ngokombono wokuhlukanisa insimbi ne-slag, le nqubo ingashiwo njengenqubo engcono kakhulu.
Ububi obukhulu bale nqubo ukuthi i-slag yensimbi ehlukanisiwe iyi-slurry ecolekile. Ngenxa yokuthi le nqubo iyinqubo emanzi, kunzima ukuyisebenzisa ekwakheni isakhiwo. Ngakho-ke, iningi lezinto ze-slag yensimbi ezisele ngemva kokukhethwa kwensimbi ziyalahlwa, futhi lokhu kuvame ukubangelwa yizindleko eziphezulu zokomisa okumanzi kanye nemikhawulo yezomthetho emhlabeni jikelele. Noma yikuphi ukusetshenziswa kwenani eliphakeme kudinga ezinye izindlela zokwelapha i-sludge emanzi (ukomisa, ukuqina, njll.).
Ngokuvamile kufanele kwenziwe ukukhetha phakathi kwesilinganiso sokubuyisa insimbi noma ukutholakala kwe-slag esele. Ngokuvamile, lokhu kukhetha kuncike enanini lensimbi etholiwe.
Izinqubo ezivamile kulesi sigaba yilezi ezilandelayo:
Izingcezu ezinkulu zichotshozwa nge-jaw crusher kuya ku--50, bese i-magnetic iron ihlukaniswa nge-pulley yamagnetic.
I-slag yensimbi engu-50 ichotshozwa nge-hammer crusher noma i-cone crusher, i-impact crusher, ihlungwe ngesihlungo esinezingqimba eziningi, umkhiqizo we-grit ongu-20-10 ungasetshenziswa njengetshe, umkhiqizo we-grit ongu-10-1 ungasetshenziswa njengesihlabathi esicolekile.

Ukuhlaziywa kosayizi wezinhlayiya ze-feed engu-50mm ku-hammer crusher
I-slag yensimbi engu-10 igxotshwa ibe yi-dry ball mill ibe yi--200 mesh fine powder, bese kusetshenziswa i-electromagnetic dry powder separator ukususa insimbi njengesithako sikasimende.
