Posachedwapa, mzere wopangira zitsulo wa slag ufa wokhala ndi mphamvu zazikulu kwambiri zopanga ku China unamalizidwa ndikuyamba kugwira ntchito ku Shagang Group.Ndalama zonse za polojekitiyi ndi pafupifupi yuan 170 miliyoni, ndipo akuti matani 600000 a ufa wa slag adzapangidwa chaka chilichonse.Chifukwa cha kuuma kwakukulu kwazitsulo zachitsulo, tinthu tating'onoting'ono ta mphero wamba ndi mphero yodzigudubuza idakali pafupifupi 6-8mm pambuyo pophwanya, zomwe zimafuna kuti mabizinesi opanga simenti ayambenso.Thechitsulo slagvertical roller mphero imagwiritsidwa ntchito popanga zitsulo zachitsulo za Shagang, zomwe "zimasiya" mwachindunji ulalo wapakatikati.The m'mimba mwake fineness wa slag zitsulo akhoza kufika za 0.003mm.Pamaziko a kuchepetsa kugwiritsira ntchito mphamvu kwa ndondomekoyi, ikhoza kuchepetsa kuopsa kwa chilengedwe, kupititsa patsogolo mtengo wowonjezera wa mankhwala, kupititsa patsogolo kusintha kwa zitsulo zachitsulo kuchokera ku "zinyalala zolimba" kupita ku "katundu", ndi kukwaniritsa "kuwongolera kawiri." ” za phindu loteteza chilengedwe komanso phindu lazachuma.Izi zikuwonetsa kuti mphero yachitsulo imakhala ndi chiyembekezo chabwino pamsika.Monga katswiri zitsulo slag ofukula wodzigudubuza mphero, HCMilling (Guilin Hongcheng) adzayambitsa ntchito msika wa zitsulo slag ofukula wodzigudubuza mphero.

zitsulo slag akuperamphero

Zikumveka kuti "chitsulo slag akupera" ndi makampani anazindikira chitetezo chilengedwe polojekiti, recyclable chuma polojekiti, komanso "kudumpha wachiwiri" wa zitsulo slag mankhwala Shagang.Mu 2020, Shagang adzamanga pulojekiti yaikulu kwambiri ya zitsulo zokwana matani 3.3 miliyoni ku China, ndikukwaniritsa 100% yokwanira yogwiritsira ntchito slag yachitsulo kupyolera mu kupatukana kwa maginito, kuphwanya, kugaya ndodo, kufufuza ndi zina zakuya.Kumapeto kwa Okutobala chaka chomwecho, pafupifupi matani 600 a zitsulo zachitsulo kuchokera ku Shagang adagwiritsidwa ntchito bwino pantchito yosintha masiponji amisewu ya Zhangjiagang.Pambuyo pazitsulo slag akuperampheromzere wopanga wayamba kugwira ntchito, chitsulo chachitsulo chasinthadi kuchokera ku "zinyalala zolimba" kupita ku "chinthu", ndipo zinthu zobwezeretsanso "zaumitsidwa ndi kufinyidwa", kupititsa patsogolo unyolo wachuma wobiriwira."M'mimba mwake wa zinthu zopangira ndi 6-8mm, ndiyeno timawaperanso ndi chitsulo chachitsulo chowongoka chowongoka, ndipo fineness amafika pafupifupi 0.003mm m'mimba mwake."Malinga ndi katswiri wochokera ku msonkhano wopukutira wa Shagang New Materials Co., mzere wamba wopangira zitsulo ndi pafupifupi matani 300000 pamakampani onse.Mzere wathu watsopano wopangira matani 600000 ndiwofotokozera zamakampani onse ndipo ndiwothandiza kwambiri pakupanga machitidwe ogwira mtima amakampani.

Kafukufuku wokhudza kakulidwe ndi kagwiritsidwe ntchito ka chitsulo cha slag micro powder ndi mutu wovuta kwambiri kutsatira kugwiritsa ntchito kwakukulu kwa ufa wa slag m'zaka zaposachedwa.Kupanga yaying'ono ufa kapena kompositi yaying'ono ufa ndi zitsulo slag akhoza kuthetsa kusiyana grindability kupanga zitsulo slag simenti.Pamene zitsulo slag pansi kwa fineness inayake ndichitsulo slag vertical roller mphero, pamene malo enieniwo ali aakulu kuposa 400m2Kg, chitsulo chachitsulo chikhoza kuchotsedwa pamlingo waukulu kwambiri.Mapangidwe a kristalo a zinthuzo amakonzedwanso ndi kupukuta kopitilira muyeso, ndipo mawonekedwe a tinthu tating'onoting'ono amasintha, Pamwambapo amatha kusintha komanso kupangitsa kuti ntchito yachitsulo ikhale yogwira ntchito, ndikusewera pamakhalidwe a hydraulic cementing materials.Pamene zitsulo za slag ufa ndi slag ufa zikuphatikizidwa, iwo ali ndi mwayi wapamwamba.Kashiamu hydroxide wopangidwa pamene C3S ndi C2S mu zitsulo slag ndi hydrated ndi chiyambi activator wa slag.Deta yaposachedwa ikuwonetsa kuti ngakhale kugwiritsa ntchito ufa wa slag ngati kusakaniza konkire kumatha kupititsa patsogolo mphamvu ya konkire ndikuwongolera magwiridwe antchito ndi kukhazikika kwa osakaniza a konkire, kutsika kwa alkalinity ya ng'anjo yamoto slag (% CaO+% MgO)/(% SiO2+% Al2O3) , pafupifupi 0.9 ~ 1.2, idzachepetsa kwambiri mchere wamadzimadzi mu konkire, kuwononga filimu yokhazikika yolimbikitsira mu konkire (pH <12.4 ndiyosavuta kuwononga), ndipo imayambitsa dzimbiri kulimbitsa konkire.Kuphatikiza apo, blast ng'anjo slag ndi vitreous thupi ndi C3AS ndi C2MS2 monga zigawo zikuluzikulu.Kutsekemera kwa granulated blast ng'anjo ya slag ufa kumachokera ku kupasuka kwa slag vitreous structure.Mankhwala a hydration amatha kupangidwa kokha pansi pa zochita za Ca (OH) 2. Slag yachitsulo imakhala ndi alkalinity yapamwamba (% CaO +% MgO) / (% SiO2), yomwe ili pafupi ndi 1.8 ~ 3.0.The mchere makamaka C3S, C2S, CF, C3RS2, RO, etc. The fCaO ndi yogwira mchere mu zitsulo slag kupanga Ca (OH) 2 pamene kukumana madzi, amene bwino madzi amchere a dongosolo konkire, Angagwiritsidwe ntchito ngati alkaline activator wa ufa wa slag.Konkire yosakanikirana ndi chitsulo cha slag ufa imakhala ndi makhalidwe amphamvu kwambiri m'nthawi yamtsogolo.Choncho, zitsulo za slag ndi slag composite ufa zingaphunzire kuchokera kwa wina ndi mzake, ndipo ntchitoyo ndi yabwino kwambiri.

Njira yopanga chitsulo slag vertical roller mphero imaphatikizidwa ndi kuphwanya, kugaya, kuyanika ndi kusankha ufa, komwe kumadziwika ndi kugwiritsa ntchito mphamvu zochepa, kusindikiza bwino, malo ang'onoang'ono apansi, njira yosavuta, ndi zina zotero. powder concentrator, kuthamanga kwa mpweya wa fani ya mphero ndi kuthamanga kwa mphero.Ndi kusintha kwa mapangidwe njira ndi malingaliro ndi kuchulukira okhwima ndondomeko luso, ndalama ofukula wodzigudubuza dongosolo mphero kwambiri yafupika, amene kwenikweni ndi ofanana kapena apamwamba pang'ono kuposa chatsekedwa dera dongosolo mphero.Chifukwa cha ubwino wake pakugwira ntchito komanso kugwiritsa ntchito mphamvu, dongosololi lidzagwiritsidwa ntchito kwambiri.HCMilling(Guilin Hongcheng) ndi katswiri zitsulo slag ofukula wodzigudubuza mphero.ZathuMtengo wapatali wa magawo HLMvertical roller mphero ndi zida zabwino kuthandiza ofukula wodzigudubuza mphero kukulitsa msika zitsulo slag ufa.Ikhoza kupera chitsulo cha slag ufa ndi malo apamwamba kwambiri oposa 700, kupulumutsa njira ziwiri zopangira chisanadze ndi kugaya komaliza, ndikumaliza kupanga chitsulo cha slag ufa mu sitepe imodzi.

Ngati muli ndi zofunikira, chonde titumizireni kuti mudziwe zambiri za zida.
