Zinyalala zazikulu za mafakitale ku China ndi monga zinyalala, phulusa la ntchentche, gangue ya malasha, slag yosungunula, slag yoyaka malasha ndi gypsum yosungunuka. Kukonzekera zipangizo zomangira kuchokera ku zinyalala zolimba kwakopa chidwi chachikulu. Ofufuzawa akweza kuchuluka kwa momwe zinyalala zolimba zimagwiritsidwira ntchito m'makampani opanga zida zomangira kudzera mu kukonza ndi kufufuza ndi kupanga zida ndi ukadaulo. Nthawi yomweyo, mayiko osiyanasiyana apereka malamulo ndi malangizo othandizira kuti alimbikitse mabizinesi kuti azikonda kugwiritsa ntchito zinyalala zolimba, motero akuwongolera momwe zinyalala zolimba za mafakitale zimakhudzira chilengedwe mpaka pamlingo winawake. Monga wopanga chitsulo chopukusira mphero, kampani yathuchitsulo choyimirira chozungulira choyimirira yagwiritsidwa ntchito kwambiri mu pulojekiti yogwiritsira ntchito zipangizo zomangira pogwiritsa ntchito mchenga wachitsulo. HCMilling (Guilin Hongcheng) idzayambitsa ukadaulo wokonzekera zipangizo zomangira kuchokera ku zitsulo zachitsulo.

1. Simenti yosungunuka ndi calcined

Kupaka chitsulo kuli ndi zinthu zambiri zachitsulo, zomwe zingalowe m'malo mwa ufa wachitsulo ngati zopangira zopangira simenti. Kuwotcha simenti clinker ndi miyala yamchere, mchenga wa quartz ndi zitsulo zachitsulo ngati zopangira kungachepetse kutentha kwa calcination ndi mtengo wa simenti, koma kuchuluka kosakaniza ndi kochepa, ndipo kuchuluka kosakaniza kwambiri kudzachepetsa kwambiri mphamvu ya simenti. Pakadali pano, kuchuluka kwa zitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga calcining simenti clinker ndi pafupifupi 15%. Ndikofunikira kwambiri kupanga zida zatsopano ndi ukadaulo watsopano kuti muwongolere kuchuluka kwa zitsulo zachitsulo ndikuwonetsetsa kuti zinthu za simenti zili bwino.

2. Chophatikiza cha konkire

Kulimba kwambiri kwa zitsulo zachitsulo makamaka kumachokera ku gawo lamkati la quartz, lomwe kukula kwake kuli pafupi ndi mchenga wachilengedwe wa mumtsinje ndi mchenga wopangidwa, ndipo limatha kusakanizidwa ndi konkriti ngati chophatikiza. Konkriti yokhala ndi mphamvu ya 28d ya pafupifupi 40MPa ikhoza kukonzedwa pogwiritsa ntchito zitsulo zachitsulo zokhala ndi kukula kwa tinthu tosakwana 1mm kuti zilowe m'malo mwa mchenga wachilengedwe wa mumtsinje ngati chophatikiza chabwino. Kutengera ndi kukonza bwino kwa chophatikiza, kugwiritsa ntchito kophatikizana kwa zitsulo ndi mchenga wopangidwa ndi makina ngati chophatikiza sikungokwaniritsa zofunikira za konkriti pazinthu zokha, komanso kumakhala kolimba kuposa kwa zitsulo zachitsulo ndi mchenga wachilengedwe wa mumtsinje, zomwe zimathandiza kwambiri kuwongolera khalidwe la konkriti. Ponena za njira yowonjezerera zinthu pakadali pano, kuti ziwongolere kuchuluka kwa zitsulo, tinthu ta zitsulo zachitsulo tikucheperachepera, zomwe zimakhala zovuta kukwaniritsa muyezo wa chophatikiza chachikulu ndikuyika pa konkriti wamba.

3. Kusakaniza kwa mchere wa konkire

Zinthu zosakaniza za mchere zimapangidwa makamaka ndi zinthu zopanda silika, calcareous ndi aluminiyamu, zomwe zimathandiza kwambiri pakukonza kukhuthala, kusalowa madzi, komanso kulimba kwa konkriti. Zingathe kuchepetsa kugwiritsa ntchito simenti ndikuchepetsa kutentha kwa madzi nthawi imodzi. Chifukwa chake, ndikofunikira kupeza zinthu zatsopano zosakaniza za mchere kuti chitukuko chokhazikika cha makampani a simenti chikhale chokhazikika. Gawo lalikulu la mchere m'magawo achitsulo nthawi zambiri ndi quartz, yomwe ili ndi ntchito yochepa ya pozzolanic m'chilengedwe. Momwe mungakulitsire "ntchito ya pozzolanic" ya magawo achitsulo yakhala nkhani yayikulu ya ofufuza amakono. Monga njira imodzi yomwe imagwiritsidwa ntchito kwambiri poyambitsa magawo achitsulo, kupukusa kwamakina kungachepetse mphamvu yoyambitsa magawo achitsulo ndikupanga zolakwika zambiri za lattice ndi kusintha kwa pulasitiki. Kafukufukuyu akuwonetsa kuti kupukusa kwamakina kungalimbikitse ntchito ya pozzolanic ya magawo wamba a mchere m'magawo achitsulo. Pamene kukula kwa tinthu ta mchere wophwanyidwa ndi makina kumachepa, quartz imatha kuchitapo kanthu ndi Ca (OH) 2 mu simenti kuti ipange calcium silicate gel yosungunuka ndi kristalo ya ettringite ndi zinthu zina zosungunulira madzi. Kafukufukuyu akusonyeza kuti pamene kupukutira kwa makina kuli kopitilira mphindi 40, ngodya yakuthwa ya chitsulo imachepa, tinthu tating'onoting'ono timaonekera, ndipo kufanana kumawonjezeka pang'onopang'ono. Mu dongosolo la anhydrite iron tailing calcium oxide, siliceous iron tailing ya makina opukutira imatha kusakanikirana ndi 30% kuti ipange simenti ya 32.5. Pansi pa chiŵerengero chochepa cha madzi omangirira, ufa wa chitsulo chofewa ukhoza kulimbikitsa kwambiri madzi oyambira a phala la simenti yophatikizika, kupangitsa kapangidwe ka matope kukhala kopapatiza, ndikuwonjezera mphamvu yoyambirira. Kuwonjezeka kwa malo enaake a chitsulo chophatikizika sikukhudza bwino ntchito yake; Kusintha kwa kutentha kophikira kumatha kukulitsa kwambiri ntchito yowerengera kumayambiriro (7d), koma sikukhudza kwenikweni ntchito yowerengera kumapeto (28d). Pa dongosolo la chitsulo chophatikizana cha slag, ntchito yowerengera ikhoza kusinthidwa mwa kukonza njira yopukutira, motero kukonza kulimba kwa konkriti. Kugwiritsa ntchito moyenera mankhwala ochepetsera madzi kumatha kuwonjezera kuchuluka kwa chitsulo chophatikizana mu konkriti wamba kuchokera pa 30% mpaka 40%. Kupera kwa chitsulo kungathandize kuti chitsulo chigwire bwino ntchito pogwiritsa ntchito mphamvu zake, motero kumalimbikitsa ntchito ya chitsulo. Mwa kukonza chiŵerengero cha chitsulo, slag, clinker ndi gypsum composite simenti, konkire yogwira ntchito bwino kwambiri yokhala ndi magwiridwe antchito okwaniritsa muyezo wa dziko lonse ikhoza kukonzedwa.
