Zinyalala zolimba zamafakitale ku China zimakhala makamaka michira, phulusa la ntchentche, gangue ya malasha, slag yosungunula, slag yoyaka malasha ndi gypsum desulfurization.Kukonzekera kwa zipangizo zomangira kuchokera ku zinyalala zolimba kwachititsa chidwi kwambiri.Ofufuzawa asintha kuchuluka kwa zinyalala zogwiritsidwa ntchito m'makampani opanga zida zomangira kudzera pakuwongolera ndi kafukufuku ndi chitukuko cha zida ndiukadaulo.Panthawi imodzimodziyo, mayiko osiyanasiyana apereka malamulo ndi malamulo othandizira kulimbikitsa mabizinesi kukhala ndi chidwi chogwiritsa ntchito zinyalala zolimba, motero kupititsa patsogolo kukhudzidwa kwa zinyalala zolimba m'mafakitale pazachilengedwe.Monga wopanga zitsulo tailings akupera mphero, wathuchitsulo tailings ofukula wodzigudubuza mphero wakhala chimagwiritsidwa ntchito chitsulo tailings mchenga akupera zomangira mabuku magwiritsidwe ntchito.HCMilling(Guilin Hongcheng) adzayambitsa luso pokonzekera zomangira tailings chitsulo.

1. Calcined simenti clinker

Chitsulo chachitsulo chimakhala ndi chitsulo chochuluka, chomwe chingalowe m'malo mwa ufa wachitsulo ngati zopangira zopangira simenti.Kuwotcha simenti clinker ndi miyala yamchere, quartz mchenga ndi tailings chitsulo monga zopangira angathe bwino kuchepetsa kutentha calcination ndi mtengo wa simenti, koma kusanganikirana kuchuluka ndi ochepa, ndipo kwambiri kusanganikirana kuchuluka kudzachepetsa kwambiri mphamvu simenti.Pakali pano, kuchuluka kwa zitsulo zachitsulo zomwe zimagwiritsidwa ntchito popukuta simenti ndi 15% yokha.Ndikofunikira kupanga zida zatsopano ndi ukadaulo watsopano kuti muwonjezere kuchuluka kwazitsulo zachitsulo ndikuwonetsetsa kuti zinthu za simenti zili bwino.

2. Konkire aggregate

Kuuma kwakukulu kwa michira yachitsulo makamaka kumachokera ku gawo lamkati la quartz, lomwe kukula kwake kwa tinthu kuli pafupi ndi mchenga wachilengedwe wa mtsinje ndi mchenga wopangidwa, ndipo amatha kusakanizidwa mu konkriti monga akaphatikiza.Konkire yokhala ndi mphamvu ya 28d pafupifupi 40MPa imatha kukonzedwa pogwiritsa ntchito michira yachitsulo yokhala ndi tinthu tating'onoting'ono tosakwana 1mm m'malo mwa mchenga wamtsinje wachilengedwe ngati wophatikiza bwino.Kutengera kukhathamiritsa kwa aggregate grading, ndi gulu ntchito tailings chitsulo ndi mchenga wopangidwa ndi makina monga aggregate sangakhoze kokha kukwaniritsa zofunika za konkire kwa zipangizo, komanso ali ndi kukhazikika bwino kuposa tailings chitsulo ndi masoka mtsinje mchenga, amene kwambiri. zothandiza kulamulira khalidwe la konkire.Monga momwe ndondomeko ya beneficiation ikukhudzidwira, kuti apititse patsogolo kuchira kwachitsulo, tinthu tating'onoting'ono tazitsulo tating'ono tating'ono tikupeza bwino kwambiri, zomwe zimakhala zovuta kuti zigwirizane ndi zofunikira zowonongeka ndikugwiritsanso ntchito ku konkire wamba.

3. Konkire mchere kusakaniza

Maminolo ophatikizika amapangidwa makamaka ndi amorphous siliceous, calcareous ndi aluminiyamu zida, zomwe zimagwira ntchito yofunika kwambiri pakuwongolera kukhazikika, kusasunthika komanso kulimba kwa konkriti.Amatha kuchepetsa kugwiritsa ntchito simenti ndikuchepetsa kutentha kwa hydration nthawi yomweyo.Chifukwa chake, ndikofunikira kupeza zophatikiza zatsopano zamamineral kuti pakhale chitukuko chokhazikika chamakampani a simenti.Gawo lalikulu la mchere muzitsulo zachitsulo nthawi zambiri zimakhala quartz, yomwe imakhala ndi zochitika zochepa za pozzolanic mu chilengedwe.Momwe mungasinthire "ntchito za pozzolanic" zazitsulo zachitsulo zakhala mutu waukulu wa ofufuza amakono.Monga imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri poyambitsa michira yachitsulo, kugaya mawotchi kumatha kuchepetsa mphamvu yazitsulo zachitsulo ndikutulutsa zolakwika zambiri za lattice ndi kupunduka kwa pulasitiki.Kafukufukuyu akuwonetsa kuti kugaya kwamakina kumatha kulimbikitsa ntchito ya pozzolanic ya magawo amchere amchere mu michira yachitsulo.Monga tinthu kukula umakaniko pansi mchere amachepetsa, khwatsi akhoza kuchita ndi Ca (OH) 2 mu simenti slurry kupanga amorphous hydrated kashiamu silicate gel osakaniza ndi ettringite galasi ndi mankhwala ena hydration.Kafukufukuyu akuwonetsa kuti pamene makina akupera amaposa 40min, mbali yakuthwa yachitsulo imachepetsedwa, tinthu tating'ono tating'ono timawonetsedwa, ndipo kufananiza kumasinthidwa pang'onopang'ono.Mu anhydrite chitsulo tailing kashiamu okusayidi dongosolo, siliceous chitsulo tailing wa makina akupera akhoza kusakaniza 30% kukonzekera 32.5 simenti.Pansi pa chiŵerengero cha madzi otsika opangira madzi, ufa wabwino wachitsulo ukhoza kulimbikitsa kusungunuka koyambirira kwa phala la simenti, kupanga pore kapangidwe ka matope kwambiri, ndikuwonjezera mphamvu zoyamba.Kuwonjezeka kwa malo enieni a zitsulo zachitsulo kulibe zotsatira zoonekeratu pakusintha ndondomeko yake ya ntchito;Kusintha kwa kutentha kwa machiritso kungathe kuonjezera chiwerengero cha zochitika kumayambiriro (7d), koma zimakhala ndi zotsatira zochepa pa ndondomeko ya zochitika kumapeto (28d).Kwa makina achitsulo a slag composite system, index ya zochitikazo zitha kusinthidwa ndikuwongolera makina akupera, motero kumapangitsa kuti konkriti ikhale yolimba.Kugwiritsa ntchito moyenera kwa madzi ochepetsera kumatha kuwonjezera zomwe zili muzitsulo zachitsulo mu konkire wamba kuchokera 30% mpaka 40%.The chitsulo tailings akupera akhoza kusintha akupera dzuwa mwa zotsatira zake, motero zolimbikitsa pozzolanic zochita za chitsulo michira.Mwa kukhathamiritsa chiŵerengero cha michira yachitsulo, slag, clinker ndi gypsum composite cementitious materials, konkire yopambana kwambiri yogwira ntchito mogwirizana ndi dziko lonse ikhoza kukonzekera.
