Inkunkuma eqinileyo yemizi-mveliso yaseTshayina ikakhulu ziintsalela, uthuthu oluyimpukane, i-gangue yamalahle, i-slag yokunyibilikisa, i-slag etshiswa ngamalahle kunye ne-desulfurization gypsum. Ukulungiswa kwezixhobo zokwakha ezivela kwinkunkuma eqinileyo kutsale ingqalelo engakumbi. Abaphandi baphucule izinga lokusetyenziswa ngokupheleleyo kwenkunkuma eqinileyo kwishishini lezixhobo zokwakha ngokuphucula nophando kunye nophuhliso lwezixhobo kunye netekhnoloji. Kwangaxeshanye, amazwe ahlukeneyo akhuphe imithetho nemigaqo exhasayo yokukhuthaza umdla wamashishini ekusebenziseni inkunkuma eqinileyo, ngaloo ndlela kuphucula impembelelo yenkunkuma eqinileyo yemizi-mveliso kwindalo esingqongileyo ukuya kwinqanaba elithile. Njengomvelisi we-iron tailings grinding mill, yethui-roller mill yemisila yentsimbi ethe nkqo Isetyenziswe kakhulu kwiprojekthi yokusetyenziswa kwezixhobo zokwakha ezisebenzisa isanti yesinyithi. I-HCMilling (Guilin Hongcheng) iza kwazisa itekhnoloji yokulungiselela izixhobo zokwakha ezisebenzisa isanti yesinyithi.

1. I-clinker yesamente ekhaltsiniweyo

Ukuthunga ngentsimbi kutyebile kwi-iron element, enokuthi ithathe indawo yomgubo wentsimbi njengezinto eziluhlaza zokuvelisa i-cement clinker. Ukutshisa i-cement clinker nge-limestone, isanti ye-quartz kunye ne-iron tailings njengezinto eziluhlaza kunokunciphisa ngempumelelo ubushushu be-calcination kunye neendleko zesamente, kodwa ubungakanani bokuxuba buncinci, kwaye ubungakanani bokuxuba obugqithisileyo buya kunciphisa kakhulu amandla esamente. Okwangoku, ubungakanani be-iron tailings ezisetyenziselwa i-calcining i-cement clinker bumalunga ne-15% kuphela. Kungxamisekile ukuphuhlisa izixhobo ezintsha kunye nobuchwepheshe obutsha ukuphucula ubungakanani be-iron tailings kunye nokuqinisekisa umgangatho weemveliso zesamente.

2. I-aggregate yekhonkrithi

Ubunzima obukhulu beentsalela zesinyithi buvela kwisigaba sangaphakathi se-quartz, esineenxalenye eziphantse zibe kufutshane nesanti yomlambo yendalo kunye nesanti eyenziweyo, kwaye sinokuxutywa kwikhonkrithi njenge-aggregate. Ikhonkrithi enamandla angama-28d angama-40MPa ingalungiswa ngokusebenzisa iintsalela zesinyithi ezinobukhulu beentsalela ezingaphantsi kwe-1mm ukuze zithathe indawo yesanti yomlambo yendalo njenge-aggregate entle. Ngokusekelwe ekuphuculeni ukuhlelwa kwe-aggregate, ukusetyenziswa kwentsalela zesinyithi kunye nesanti eyenziwe ngomatshini njenge-aggregate akunakuhlangabezana neemfuno zekhonkrithi yezinto zokwakha kuphela, kodwa kukwanozinzo olungcono kunezo zentsalela zesinyithi kunye nesanti yomlambo yendalo, nto leyo enceda ngakumbi ekulawuleni umgangatho wekhonkrithi. Ngokuphathelele inkqubo yokuphucula ngoku, ukuze kuphuculwe izinga lokubuyiswa kwesinyithi, iintsalela zentsalela zesinyithi ziya zisiba zincinci, nto leyo enzima ukuhlangabezana nomgangatho wentsalela erhabaxa kwaye zisetyenziswe kwikhonkrithi eqhelekileyo.

3. Umxube weeminerali zekhonkrithi

Iiminerali ezidityanisiweyo zenziwe kakhulu ngezinto ze-siliceous, calcareous kunye ne-aluminium, ezidlala indima ebalulekileyo ekuphuculeni ubuncinci, ukungangeni kunye nokuqina kwekhonkrithi. Zinokunciphisa ukusetyenziswa kwesamente kwaye zinciphise ubushushu bokufuma kwangaxeshanye. Ke ngoko, kubalulekile ukufumana iiminerali ezintsha zophuhliso oluzinzileyo lweshishini lesamente. Isigaba esiphambili seminerali kwiintsalela zesinyithi sidla ngokuba yi-quartz, enomsebenzi omncinci we-pozzolanic kwimeko yendalo. Indlela yokuphucula "umsebenzi we-pozzolanic" weentsalela zesinyithi ibe yingongoma ephambili yabaphandi bangoku. Njengenye yeendlela ezisetyenziswa kakhulu ekusebenzeni kweentsalela zesinyithi, ukugaywa koomatshini kunokunciphisa amandla okusebenza kweentsalela zesinyithi kwaye kuvelise iziphene ezininzi ze-lattice kunye nokuguqulwa kweplastiki. Uphando lubonisa ukuba ukugaywa koomatshini kunokukhuthaza umsebenzi we-pozzolanic wezigaba eziqhelekileyo zeeminerali kwiintsalela zesinyithi. Njengoko ubungakanani beesuntswana zeeminerali ezigaywa ngoomatshini buncipha, i-quartz inokusabela nge-Ca (OH) 2 kwi-slurry yesamente ukuvelisa i-amorphous hydrated calcium silicate gel kunye ne-ettringite crystal kunye nezinye iimveliso ze-hydration. Uphando lubonisa ukuba xa ukugaya ngoomatshini kungaphezulu kwemizuzu engama-40, i-engile ebukhali yee-iron tailings iyancitshiswa ngokucacileyo, amasuntswana amancinci ayabonakala, kwaye ukufana kuyaphucuka kancinci kancinci. Kwinkqubo ye-anhydrite iron tailing calcium oxide, i-siliceous iron tailing yokugaya ngoomatshini ingaxutywa ne-30% ukulungiselela isamente engama-32.5. Phantsi kwesimo somlinganiselo ophantsi we-water binder, i-fine iron tailings powder inokukhuthaza kakhulu ukufuma kwasekuqaleni kwe-composite cement paste, yenze ulwakhiwo lwe-pore ye-mortar lube mncinci ngakumbi, kwaye iphucule amandla okuqala. Ukwanda kwendawo ethile yomphezulu wee-iron tailings akunampembelelo icacileyo ekuphuculeni i-activity index yayo; Utshintsho lobushushu bokuphilisa lunokunyusa kakhulu i-activity index kwinqanaba lokuqala (7d), kodwa alunampembelelo ingako kwi-activity index kwinqanaba lokugqibela (28d). Kwinkqubo ye-iron tailings slag composite, i-activity index inokuphuculwa ngokuphucula indlela yokugaya, ngaloo ndlela kuphuculwe ukuqina kwekhonkrithi. Ukusetyenziswa ngokufanelekileyo kwe-arhente yokunciphisa amanzi kunokunyusa umxholo wee-iron tailings kwikhonkrithi eqhelekileyo ukusuka kwi-30% ukuya kwi-40%. Ukusila ii-iron tailings kunokuphucula ukusebenza kakuhle kokusila ngesiphumo sako, ngaloo ndlela kuvuselele umsebenzi we-pozzolanic wee-iron tailings. Ngokuphucula umlinganiselo wee-iron tailings, i-slag, i-clinker kunye nezinto ze-gypsum composite cementitious, ikhonkrithi esebenza kakhulu enentsebenzo ehlangabezana nomgangatho wesizwe ingalungiselelwa.
