Ngowama-2015, umqambi uCui Weihua watyhila ilungelo lomenzi: indlela yokulungiselela i-calcium carbonate ekhaphukhaphu ephezulu evela kwi-slag yentsimbi. Ngaba kunokwenzeka ukwenza i-calcium carbonate ekhaphukhaphu ephezulu evela kwi-slag yentsimbi usebenzisa i-slag yentsimbi i-roller mill ethe nkqo?

Ngokutsho kweChina Powder Technology Network, kutshanje, "umgca wokubonisa ukusetyenziswa kwemizi-mveliso ye-carbonization ye-iron kunye ne-steel slag ye-100000 ton", iprojekthi evunyelweneyo "yokuvuselela iMongolia ngesayensi netekhnoloji", yaqaliswa eBaotou. Le projekthi yakhiwe ngokubambisana yiBaotou Steel Group kunye neYukuang Environmental Protection Technology (Shanghai) Co., Ltd. Kubikwa ukuba le projekthi isekelwe kwiziphumo "zomgca wemveliso yokuqinisekisa iitoni ezili-10,000 zokusetyenziswa ngokupheleleyo kwe-steel slag ngendlela ye-carbonization". I-steel slag yenziwe nge-carbon ngokupheleleyo, kwaye ekugqibeleni ivelisa iimveliso zemizi-mveliso ezifana ne-calcium carbonate ecocekileyo kakhulu kunye nezinto eziqulathe isinyithi, ukuze kusetyenziswe kwakhona izixhobo ze-steel slag. Xa kuthelekiswa netekhnoloji yendabuko, itekhnoloji yonyango lwe-carbonization yentsimbi kunye ne-steel slag inokuthabatha ngqo i-carbon dioxide njengezinto eziluhlaza ukuze ithathe inxaxheba kwimpendulo ngelixa inciphisa ukukhutshwa kwe-carbon dioxide, enefuthe eliphindwe kabini lokunciphisa ikhabhoni, ifezekisa injongo yokunciphisa ukukhutshwa kwegesi eluhlaza kunye nokukhuthaza uphuhliso lwe-circular low-carbon. Emva kokugqitywa kwale projekthi, iitoni ezingama-424000 ze-slag yentsimbi zinokunyangwa minyaka le, ngelixa malunga neetoni ezili-100000 ze-carbon dioxide zinokufakwa kwi-carbon dioxide (zivalwe), kwaye amandla emveliso eetoni ezingama-200000 ze-calcium carbonate ecocekileyo kakhulu kunye neetoni ezingama-310000 zezixhobo zesinyithi zinokufezekiswa. Le projekthi yindlela yokubonisa ngakumbi ephucukileyo, enokukhuthaza kakhulu kumashishini afanayo. Ngelixa ihlangabezana neemfuno zokusetyenziswa ngokupheleleyo kwenkunkuma eqinileyo, iluncedo ekufezekiseni injongo ye-carbon peak kunye ne-carbon neutralization. Oku kuthetha ukuba kunokwenzeka iprojekthi yokuvelisa i-calcium carbonate ecocekileyo kakhulu kwi-slag yentsimbi. Ikwabonelela ngendlela entsha yokusetyenziswa ngokupheleleyo kwenkunkuma eqinileyo ye-slag yentsimbi.

Iimpawu eziphambili zobugcisa zokuvelisa i-calcium carbonate ecocekileyo kakhulu kwi-slag yentsimbi zezi zilandelayo: okokuqala, tyuba i-slag yentsimbi ibe ngumgubo, tyhila i-calcium oxide ekhululekileyo kwi-slag yentsimbi kumphezulu we-slag yentsimbi, khupha i-calcium oxide kwi-slag yentsimbi ngendlela emanzi nge-0.5% ye-acetic acid, uyihluze kwaye uyicacise, uze uyifake i-carbon dioxide ngegesi, uze uyisuse emanzini, uyihlambe, uyomise, uyipholise, uyityumze kwaye uyikhusele ukuze ivelise i-calcium carbonate ekhanyayo ecocekileyo kakhulu. I-calcium carbonate ekhanyayo ecocekileyo kakhulu isetyenziswa kakhulu njengesizalisi seetayile zomgangatho ezenziweyo, irabha, iiplastiki, ukwenza amaphepha, iingubo, iipeyinti, ii-inki, iintambo, izixhobo zokwakha, ukutya, amayeza, amalaphu, ukutya, i-toothpaste kunye nezinye iimveliso. Kule nkqubo, ubunono bokugaywa kwe-slag yentsimbi kufuneka bufikelele kwi-meshes ezingaphezu kwama-400. Luhlobo luni lwezixhobo olunokusetyenziswa ukufezekisa imveliso enkulu ye-slag micro powder yentsimbi? Njengomenzi oqeqeshiweyo weintsimbiisixhobo sokugaya i-slag, I-HCMilling (Guilin Hongcheng) icebisa ukuba ukhetheI-HLM steel slagi-roller mill ethe nkqo ukuveliswa komgubo we-slag wentsimbi. Okwangoku, inkqubo yokunyanga umgubo we-slag wentsimbi emarikeni ikakhulu kukuqala kokugaywa + ukugaywa okucolekileyo. I-slag yentsimbi ingagaywa ibe ngaphezulu kwe-420 microns emva kokugaywa ngamanqanaba amabini. Ixabiso lezixhobo, indawo yomgangatho kunye nokusetyenziswa kwamandla okuqhelekileyo zonke zityalo-mali olukhulu.

Iqela le-R&D le-HCMilling (Guilin Hongcheng) kunye neengcali zoshishino, ngokusebenzisa intsebenziswano enzulu kunye novavanyo, baqalise i-I-slag yentsimbi ye-HLM seriesi-roller mill ethe nkqo, enokucola umgubo we-slag wentsimbi ube yimo ngaxeshanye, iphucula kakhulu ixabiso lokusetyenziswa komgubo we-slag wentsimbi, kwaye ivula imakethi yesicelo esisezantsi. Sisixhobo esifanelekileyo somgubo we-slag wentsimbi ukonga iindleko, ukusetyenziswa kwamandla, indawo yomgangatho, isivuno kunye nexabiso elongezelelweyo leemveliso ezigqityiweyo.

Ukuba unesidingo sokwenza nokucubungula umgubo we-slag wentsimbi, nceda unxibelelane nathi ukuze ufumane iinkcukacha kwaye usinike ulwazi olulandelayo:
