Njengoko ilizwe lifaka ukubaluleka kokukhuselwa kwendalo, njengoluhlobo lwenkunkuma eqinileyo, indlela yokusebenzisa i-slag yensimbi ibe yinto ebalulekileyo. Eli nqaku lizisa isisombululo sobugcisa esibanzi kwi-steel slag recycling.I-teknoloji yokucoca i-Dry kufuneka iqinisekise ukubuyiswa ngokufanelekileyo kwesinyithi kwelinye icala kunye nokusetyenziswa okubanzi kweentsalela zenkunkuma kwelinye. La manyathelo alandelayo okwenziwa kwe-slag yentsimbi achazwe: Ukutyumza okukhethiweyo; ukwahlukana kwamagnetic kunye nendima yesixhobo esitsha se-single-drive high-pressure roller mill kusetyenziso olubanzi lwe-slag yensimbi; ukusetyenziswa kwezixhobo ezitsha kunokunciphisa kakhulu iindleko zokutyumzwa kwe-slag yensimbi, ngaloo ndlela kudala inzuzo eninzi yokusetyenziswa kwe-slag yensimbi. Ukukhuthazwa kokusetyenziswa ngokubanzi kwe-slag yensimbi kuye kwadala ukuba kunokwenzeka. Ukukhuthazwa kolu luvo lubanzi kushishino kufuna iinzame ezidibeneyo zeenkampani zokwenziwa kwentsimbi, iingcali zokulungisa izimbiwa kunye nabaphengululi, ukuphunyezwa ngokubanzi kwesicelo, kunye namasebe okuthengisa nokukhuthaza.
Ukwakhiwa kokusetyenziswa kwe-slag yensimbi
1) I-Slag yensimbi isetyenziselwa ukuvelisa i-samente kunye ne-concrete admixtures. I-slag yensimbi iqulethe iiminerali ezisebenzayo ezifana ne-tricalcium silicate (C3S), i-dicalcium silicate (C2S) kunye nentsimbi ye-aluminate eneempawu ze-hydraulic cementing, ezihambelana neempawu zesamente. Ngoko ke, ingasetyenziselwa njengento ekrwada kunye ne-samente admixture yokuvelisa i-samente engekho-clinker, i-samente encinci ye-clinker. I-samente ye-Slag yensimbi ineempawu ezibalaseleyo ezifana nokunganyangeki, amandla aphezulu aguquguqukayo, ukuxhathisa umhlwa kunye nokumelana neqabaka.
2) I-Slag yensimbi ithatha indawo yelitye elichotshoziweyo kunye ne-fine aggregate. Ilitye elichotshoziweyo le-steel slag lineenzuzo zamandla aphezulu, indawo erhabaxa, ukumelana nokunxiba kakuhle kunye nokuqina, umthamo omkhulu, uzinzo oluhle, kunye nokudibanisa okuqinileyo kunye ne-asphalt. Xa kuthelekiswa nelitye eliqhekeziweyo eliqhelekileyo, liphinda lixhathise kwiimpawu zeqondo lokushisa eliphantsi, ngoko linokusetyenziswa ngokubanzi kwi-backfill yobunjineli bendlela. I-Slag yensimbi, njenge-ballast kaloliwe, ineempawu zokungaphazamisi umsebenzi wonxibelelwano lwenkqubo kaloliwe kunye nokuhanjiswa kombane kakuhle. Ngenxa yokuba i-slag yensimbi inokugqithiswa kakuhle kwamanzi kunye ne-drainage, amacandelo e-cementitious kuyo angayenza ibe nzima ibe ngamaqhekeza amakhulu. I-Steel slag nayo ifanelekile ukwakhiwa kweendlela kwimigxobhozo kunye neelwandle.
Okwangoku, eyona ndlela iqhelekileyo yasekhaya yokusetyenziswa kwe-slag kukutyumza i-slag yentsimbi ukuya kwi-5mm ukubuyisela isanti yomlambo njengesixhobo sokwakha, okanye ukugaya i-slag yentsimbi etyunyuziweyo ibe ngumgubo ocolekileyo ukuze isetyenziswe njengedibansi yesamente. I-Shandong Huate Magnetoelectric Technology Co., Ltd. iye yaqhuba uphando olunzulu malunga nokusetyenziswa okubanzi kwe-slag yensimbi, yasebenzisa ngokutsha i-single-drive high-pressure roller mill ukutyumza i-slag yensimbi, iphucule iteknoloji yokucubungula i-steel slag, kwaye sizuze iinzuzo ezintle kwezoqoqosho. Isetyenziswe ngempumelelo kwi-Pangang Mining kunye neshishini elithile le-slag yensimbi e-Lianyungang.
Inkqubo yemveli yokuvelisa i-slag yensimbi yile ilandelayo:
I-1) Iziqwenga ezinkulu zityunyuzwa nge-crusher yomhlathi ukuya kwi-50, kwaye intsimbi yamagnetic ihlukaniswe nge-pulley magnetic.
2) Beka ubungakanani bokuhlukana kwentsimbi ukuya +45 mm. I-0-45 mm eseleyo idla ngokusetyenziswa njengokwakhiwa kwendlela kunye nezixhobo zokuzalisa. Ukuze ukwandise ixabiso layo lesicelo, i-slag yensimbi ingahlulwa ibe yi-0-4, 4-8 kunye namanye amabakala ahlukeneyo. Itekhnoloji ifuna imali encinci kunye neendleko eziphantsi zokusebenza. Nangona kunjalo, ngaphezu kwe-50% yomxholo wetsimbi kwi-slag igxininiswe kwi--10 mm force, ngoko le teknoloji iya kubangela ubuninzi belahleko yesinyithi, kodwa umxholo wensimbi onzima uya kwanda.
Ngoko ke, ukugaya okulungileyo okumanzi kusetyenziswe ngokubanzi ngokukodwa kwi-slag eveliswe ekwenzeni i-high-alloy steel equkethe i-high-grade Cr, i-Ni, i-Mo, njl. ). Ekubeni isinyithi esine-ductility akulula ukusila, ukuhlukana kwesinyithi kunye ne-slag yensimbi kunokufezekiswa ngokucoca okanye ukuhlelwa. Ukulunga kwenxalenye yeminerali ye-slag ngokuqhelekileyo ingaphezulu kwe-95% nangaphantsi kwe-0.2mm. Izinga lokubuyisela isinyithi sale nkqubo lidlula i-95%, kwaye isivuno se-metal concentrate eveliswa yi-90 ukuya kwi-92%. Ukususela kumbono wokwahlula isinyithi kunye ne-slag, le nkqubo inokuthiwa yinkqubo engcono kakhulu.
Ukungalungi okuphambili kwale nkqubo kukuba i-slag yensimbi ehlukeneyo i-slurry-grained slurry. Ngenxa yokuba inkqubo yinkqubo emanzi, kunzima ukufaka isicelo ekwakhiweni kwesakhiwo. Ngoko ke, ininzi ye-slag yensimbi eseleyo emva kokukhethwa kwesinyithi ilahlwa, kwaye oku kudla ngenxa yeendleko eziphezulu zokumisa okumanzi kunye nezithintelo ezisemthethweni emhlabeni jikelele. Naluphi na usetyenziso lwexabiso eliphezulu lufuna ezinye iindlela zokunyanga i-sludge emanzi (ukomisa, ukuqina, njl.).
Ukhetho kufuneka lwenziwe ngokuqhelekileyo phakathi kwezinga lokubuyisela isinyithi okanye ukufumaneka kwe-slag eseleyo. Ngokuqhelekileyo, olu khetho luxhomekeke kwixabiso lentsimbi efunyenweyo.
Iinkqubo eziqhelekileyo kwesi sigaba zezi zilandelayo:
Iziqwenga ezinkulu zityunyuzwa nge-crusher yomhlathi ukuya kwi-50, kwaye intsimbi yamagnetic ihlukaniswe ne-pulley magnetic.
-I-50 yensimbi ye-slag ityunyuzwe ngesando sokutyumza okanye i-cone crusher, isityuli sempembelelo, sieved nge-multi-layer sieve, -20-10 imveliso yegrit ingasetyenziswa njengegrabile, -10-1 imveliso yegrit ingasetyenziswa njengesanti ecocekileyo.

Uhlalutyo lwesayizi ye-particle ye-50mm feed kwi-hammer crusher
-10 grain steel slag igutywa ibeyibhola eyomileyo ibe yi -200 mesh yomgubo ocolekileyo, kuze emva koko i-electromagnetic powder dry separator isetyenziswe ukususa intsimbi njengento edibanisa nesamente.
