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 use industrialization demonstration", iphrojekthi enenkontileka "yokuvuselela iMongolia ngesayensi nobuchwepheshe", yethulwe e-Baotou.Lo msebenzi wakhiwa ngokuhlanganyela i-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 be-carbonization iron kanye ne-steel slag yokwelashwa bungathatha ngokuqondile i-carbon dioxide njengento eluhlaza ukuze babambe iqhaza ekuphenduleni ngenkathi kunciphisa ukukhishwa kwe-carbon dioxide, okunomphumela wokuncishiswa kwekhabhoni kabili, ukufeza umgomo wokunciphisa ukushisa. ukukhishwa kwegesi kanye nokukhuthaza ukuthuthukiswa kwe-circular low-carbon.Ngemuva kokuphothulwa kwephrojekthi, amathani angama-424000 we-slag yensimbi angelashwa minyaka yonke, kanti amathani angaba ngu-100000 e-carbon dioxide angafakwa (avalwe), kanye namandla okukhiqiza amathani angama-200000 we-high-purity calcium carbonate kanye namathani angama-310000 ensimbi. izinto zokwakha zingafinyelelwa.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 zobuchwepheshe eziyinhloko zokukhiqiza i-high-purity calcium carbonate kusuka ku-steel slag yilezi ezilandelayo: okokuqala, gaya i-slag yensimbi ibe yimpushana, uveze i-calcium oxide yamahhala e-slag yensimbi ebusweni be-slag yensimbi, khipha i-calcium oxide i-steel slag ngendlela emanzi nge-acetic acid engu-0.5%, isihlungi futhi icacise, bese i-carbonize nge-carbon dioxide gas, bese iqeda amanzi, igeze, yomile, ipholile, iyiphahlaze futhi uyihlole ukuze ikhiqize 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:
