Ngo-2015, umsunguli u-Cui Weihua wadalula ilungelo lobunikazi: indlela yokulungisa ukukhanya okuphezulu kwe-calcium carbonate kusuka ku-slag yensimbi. Kungenzeka yini ukwenza i-high-purity calcium carbonate kusuka ku-steel slag usebenzisa insimbi slag mpo roller mill?

Ngokusho kwe-China Powder Technology Network, muva nje, "i-100000 ton carbonization method of iron and steel slag comprehensive utilization industrialization line , iphrojekthi enenkontileka "yokuvuselela iMongolia ngesayensi nobuchwepheshe", yethulwe e-Baotou. Le phrojekthi yakhiwa ngokuhlanganyela yi-Baotou Steel Group kanye ne-Yukuang Environmental Protection Technology (Shanghai) Co., Ltd. Kubikwa ukuthi le phrojekthi isuselwe emiphumeleni yolayini wokukhiqiza wokuqinisekisa wamathani ayi-10,000 ukuze kusetshenziswe ngokuphelele i-slag yensimbi ngendlela ye-carbonization". I-steel slag ifakwe ikhabhoni ngokuphelele, futhi ekugcineni ikhiqiza imikhiqizo evela ezimbonini efana ne-high-purity calcium carbonate nezinto eziqukethe insimbi, ukuze kubonwe ukusetshenziswa kabusha kwensiza ye-slag yensimbi. Uma kuqhathaniswa nobuchwepheshe bendabuko, ubuchwepheshe bokwelashwa kwe-carbonization iron kanye ne-steel slag bungathatha ngokuqondile i-carbon dioxide njengento eluhlaza ukuze bahlanganyele ekuphenduleni ngenkathi kunciphisa ukukhishwa kwe-carbon dioxide, okunomphumela wokuncishiswa kwekhabhoni kabili, ukufeza umgomo wokunciphisa ukukhishwa kwegesi ebamba ukushisa kanye nokukhuthaza ukuthuthukiswa kwesiyingi se-carbon dioxide. Ngemva kokuphothulwa kwephrojekthi, amathani angu-424000 we-slag yensimbi angelashwa njalo ngonyaka, kanti amathani angaba ngu-100000 we-carbon dioxide angafakwa (avalwe), futhi amandla okukhiqiza amathani angu-200000 we-high-purity calcium carbonate kanye namathani angu-310000 wezinto zensimbi angafinyelelwa. Le phrojekthi iwukuhlola okwengeziwe kwezimboni, okungathuthukiswa kabanzi emabhizinisini afanayo. Ngenkathi kuhlangatshezwana nesidingo sokusetshenziswa okuphelele kwemfucuza eqinile, kuyasiza ekufinyeleleni umgomo we-carbon peak kanye ne-carbon neutralization. Lokhu kusho ukuba nokwenzeka kwephrojekthi yokukhiqiza i-high-purity calcium carbonate kusuka ku-steel slag. Iphinde inikeze indlela entsha yokusetshenziswa okuphelele kwemfucuza eqinile ye-steel slag.

Izici eziyinhloko zobuchwepheshe zokukhiqiza i-high-purity calcium carbonate kusuka ku-slag yensimbi zimi kanje: okokuqala, gaya i-slag yensimbi ibe yimpushana, uveze i-calcium oxide yamahhala ku-slag yensimbi ebusweni be-slag yensimbi, khipha i-calcium oxide ku-slag yensimbi ngendlela emanzi nge-acetic acid engu-0.5%, isihlungi bese ucacisa, bese ubeka i-carbonize bese, i-carbon desh, i-desh epholile, isikrini se-carbon dioxide, i-desh eyomile, isikrini esipholile ukukhiqiza ukukhanya okuphezulu kwe-calcium carbonate. Ukukhanya okuphezulu kwe-calcium carbonate kusetshenziswa kabanzi njengokugcwalisa amathayela aphansi okwenziwa, irabha, amapulasitiki, ukwenza amaphepha, okokunamathela, opende, oyinki, izintambo, izinto zokwakha, ukudla, umuthi, izindwangu, okuphakelayo, umuthi wokuxubha neminye imikhiqizo. Kule nqubo, ukucoleka kokugaya kwe-steel slag kudinga ukufinyelela kumameshe angaphezu kuka-400. Hlobo luni lwemishini engasetshenziswa ukufeza ukukhiqizwa okukhulu kwe-steel slag micro powder? Njengomkhiqizi ochwepheshe weinsimbiumshini wokugaya i-slag, I-HCMilling(Guilin Hongcheng) incoma ukuthi ukhetheI-HLM yensimbi slagmpo roller mill ukukhiqizwa kwe-steel slag powder. Njengamanje, inqubo yokwelapha ye-steel slag powder emakethe ikakhulukazi i-pre grinding + fine grinding. I-slag yensimbi ingagaywa ibe ngaphezu kwama-microns angu-420 ngemva kokugaya izigaba ezimbili. Intengo yemishini, indawo ephansi kanye nokusetshenziswa kwamandla okumaphakathi konke kuwukutshalwa kwezimali okukhulu.

Ithimba le-R&D le-HCMilling(Guilin Hongcheng) kanye nochwepheshe bezimboni, ngokubambisana okujulile nokuhlola, bethule uhlelo.HLM uchungechunge steel slagmpo roller mill, engakwazi ukugaya i-steel slag powder ibe yisimo ngesikhathi esisodwa, ithuthukise kakhulu inani lokusetshenziswa kwe-steel slag powder, futhi ivule imakethe yesicelo esingezansi. Kuyinto efanelekile yensimbi ye-slag micro powder okonga izindleko, ukusetshenziswa kwamandla, indawo ephansi, isivuno kanye nenani elengeziwe lemikhiqizo eqediwe.

Uma unesidingo sokukhiqizwa nokucubungula kwe-steel slag powder, sicela usithinte ukuze uthole imininingwane futhi usinikeze imininingwane elandelayo:
