Muna 2015, muvambi Cui Weihua akaburitsa patent: nzira yekugadzirira yakakwirira-kuchena mwenje calcium carbonate kubva musimbi slag. Zvinokwanisika here kugadzira yakakwirira-kuchena calcium carbonate kubva kusimbi slag uchishandisa simbi slag vertical roller chigayo?

Maererano neChina Powder Technology Network, nguva pfupi yadarika, "100000 ton carbonization method iron and steel slag comprehensive utilization industrialization demonstration line", chirongwa chakabvumiranwa che "kuvandudza Mongolia kuburikidza nesainzi uye tekinoroji", chakatangwa muBaotou. Iyo purojekiti yakavakwa pamwe chete neBaotou Steel Group uye Yukuang Environmental Protection Technology (Shanghai) Co., Ltd. Zvinonzi chirongwa ichi chakavakirwa pamhedzisiro ye "10,000 ton verification yekugadzira mutsara wekushandiswa kwakadzama kwesimbi slag necarbonization nzira". Iyo simbi slag yakazara carbonized, uye pakupedzisira inogadzira maindasitiri ne-zvigadzirwa zvakaita seyakakwirira-kuchena calcium carbonate uye iron ine zvinhu, kuitira kuti uone mashandisirwo ekushandisazve simbi slag. Kuenzaniswa nehunyanzvi hwechinyakare, iyo carbonization iron uye simbi slag kurapwa tekinoroji inogona zvakananga kutora kabhoni dhaimoni seyakagadzirwa kuti itore chikamu mukuita uku ichidzikisa kuburitswa kwekabhoni dioxide, iyo ine mbiri yekudzikisa kabhoni mhedzisiro, kuzadzisa chinangwa chekudzikisa greenhouse gasi kuburitswa uye kusimudzira kuvandudzwa kwedenderedzwa yakaderera-kabhoni. Mushure mekupedzwa kweprojekti, 424000 matani esimbi slag anogona kurapwa gore rega rega, nepo anenge 100000 matani ecarbon dioxide anogona kuve carbonized (akaiswa chisimbiso), uye simba rekugadzira re200000 matani epamusoro-kuchena calcium carbonate uye 310000 matani emidziyo yesimbi inogona kuwanikwa. Iyi purojekiti ndeyekuwedzera maindasitiri ekuratidzira kuongorora, iyo inogona kusimudzirwa zvakanyanya mumabhizinesi akafanana. Ndichiri kusangana nechido chekushandiswa kwakazara kwemarara akasimba, zvinogoneka pakuzadzisa chinangwa checarbon peak uye carbon neutralization. Izvi zvinoreva kugona kweprojekiti yekugadzira yakakwirira-kuchena calcium carbonate kubva kusimbi slag. Inopawo nzira itsva yekushandiswa kwakazara kwesimbi slag yakasimba tsvina.

Hukuru hwehunyanzvi hwekugadzira yakakwirira-kuchena calcium carbonate kubva musimbi slag ndeiyi: kutanga, kukuya simbi slag kuita upfu, buritsa yakasununguka calcium oxide musimbi slag kusvika pamusoro pesimbi slag, bvisa calcium oxide musimbi slag nenzira yekunyorova ne 0.5% acetic acid, sefa uye kujekesa, ipapo carbonize iyo uye ipapo, carbon desh uye mhepo inotonhorera, inotonhorera iyo ne carbon desh, wai inotonhorera, inotonhorera uye ipapo carbon desh, gasi rinotonhorera kugadzira yakakwirira-kuchena chiedza calcium carbonate. Yakakwirira kuchena mwenje calcium carbonate inoshandiswa zvakanyanya sekuzadza kune artificial floor tiles, rabha, mapurasitiki, kugadzira mapepa, machira, pendi, ingi, tambo, zvekuvakisa, chikafu, mushonga, machira, chikafu, mushonga wemazino nezvimwe zvigadzirwa. Muchiitiko ichi, kukuya fineness yesimbi slag inoda kusvika kupfuura 400 meshes. Ndeupi rudzi rwemidziyo inogona kushandiswa kuwana yakakura-yakakura kugadzirwa kwesimbi slag micro poda? Semugadziri wenyanzvi wesimbislag grinding guyo, HCMilling(Guilin Hongcheng) inokurudzira kuti usarudzeHLM simbi slagvertical roller chigayo nokuda kwekugadzirwa kwesimbi slag powder. Parizvino, maitiro ekurapa esimbi slag poda pamusika anonyanya kufaya + kugaya zvakanaka. Iyo simbi slag inogona kukuyiwa kune anopfuura 420 microns mushure mematanho maviri ekukuya. Mutengo wemidziyo, nzvimbo yepasi uye avhareji mashandisirwo emagetsi ese mahombe ekudyara.

HCMilling(Guilin Hongcheng)'s R&D timu uye nyanzvi dzeindasitiri, kuburikidza nekubatana kwakadzama uye bvunzo, yakatangaHLM akatevedzana simbi slagvertical roller chigayo, iyo inogona kukuya simbi slag poda kuita chimiro panguva imwe, ichinatsiridza zvakanyanya kukosha kwekushandiswa kwesimbi slag poda, uye kuvhura iyo yakaderera application musika. Iyo yakanakira simbi slag micro poda zvishandiso kuchengetedza mutengo, kushandiswa kwesimba, pasi nzvimbo, goho uye yakawedzera kukosha kwezvakapera zvigadzirwa.

Kana iwe uine kudiwa kwesimbi slag poda kugadzirwa uye kugadzirisa, ndapota taura nesu kuti uwane ruzivo uye upe ruzivo rwekutevera kwatiri:
