MaChina akawanda maindasitiri akasimba tsvina anonyanya kumisa, nhunzi dota, marasha gangue, kunyungudutsa slag, marasha-anopfuta marasha uye desulfurization gypsum.Kugadziriswa kwezvinhu zvekuvaka kubva mumarara akaoma kwakakwezva zvakanyanya uye zvakanyanya kutarisirwa.Vatsvagiri vakavandudza huwandu hwekushandiswa kwemarara akasimba muindasitiri yezvivakwa zvekuvaka kuburikidza nekuvandudza uye kutsvagisa nekuvandudza kwemidziyo uye tekinoroji.Panguva imwe cheteyo, nyika dzakasiyana-siyana dzakapa mitemo inotsigira nemirau kuti ikurudzire shungu dzemabhizinesi pakushandisa marara, nokudaro kuvandudza kukanganiswa kwemarara akasimba muindasitiri kune zvakatipoteredza kusvika kumwero wakati.Semugadziri wesimbi yekukuya mill, yeduiron tailings vertical roller mill yakashandiswa zvakanyanya musimbi tailings jecha rekukuya zvivakwa zvekuvaka yakazara yekushandisa chirongwa.HCMilling(Guilin Hongcheng) ichaunza tekinoroji yekugadzira zvinhu zvekuvaka kubva kumatare esimbi.

1. Calcined simende clinker

Iron tailing yakapfuma mune iron element, iyo inogona kutsiva iron poda seyakabikwa yekugadzira simende clinker.Kupisa simende clinker ine limestone, jecha requartz uye masimbi esimbi semidziyo yakasvibirira inogona kunyatso kudzikisa tembiricha yecalcination uye mutengo wesimende, asi huwandu hwekusanganisa hushoma, uye kuwanda kwekusanganiswa kunoderedza zvakanyanya simba resimende.Parizvino, huwandu hwesimbi tailings inoshandiswa calcining simende clinker inongova 15%.Zviri kukurumidza kugadzira michina mitsva uye tekinoroji nyowani yekuvandudza huwandu hwesimbi tailings uye kuve nechokwadi chemhando yezvigadzirwa zvesimende.

2. Concrete aggregate

Kuomarara kwesimbi kwesimbi kunonyanya kunobva muchikamu chemukati chequartz, icho saizi yechikamu chiri padyo nejecha rerwizi rwechisikigo uye jecha rakagadzirwa, uye rinogona kusanganiswa mukongiri semuunganidzwa.Iko kongiri ine 28d simba reinenge 40MPa inogona kugadzirwa nekushandisa simbi miswe ine particle size isingasviki 1mm kutsiva yakasikwa rwizi jecha seyakakwana aggregate.Zvichienderana nekukwenenzverwa kweaggregate giredhi, kushandiswa kwakasanganiswa kwesimbi uye jecha rakagadzirwa nemuchina semusanganiswa haungogone kuzadzisa zvinodiwa zvekongiri yezvigadzirwa, asiwo kune kugadzikana kuri nani pane kuya kwesimbi uye jecha rerwizi rwechisikigo, iro rakawanda. inobatsira pakutonga kwekongiri yehutano.Nezvezvino maitiro ekubatsirikana ane chekuita, kuitira kuvandudza mwero wekudzoreredza simbi, zvimedu zvesimbi zviri kuramba zvichiwedzera kunaka, izvo zvakaoma kuzadzisa mwero weiyo coarse aggregate uye kushandisa kune yakajairika kongiri.

3. Concrete mineral admixture

Mineral admixtures anonyanya kuumbwa neamorphous siliceous, calcareous uye aluminium zvinhu, izvo zvinoita basa rakakosha mukuvandudza compactness, kusamira uye kusimba kwekongiri.Vanogona kuderedza kushandiswa kwesimende uye kuderedza kupisa kwe hydration panguva imwe chete.Naizvozvo, zvakakosha kuwana mitsva yemamineral admixtures ekusimudzira indasitiri yesimende.Iyo huru yemaminerari chikamu musimbi tailings inowanzova quartz, iyo ine zvishoma pozzolanic chiitiko mune zvakasikwa.Maitiro ekuvandudza iyo "pozzolanic chiitiko" yesimbi tailings yave iyo huru musoro wevaongorori vemazuva ano.Seimwe yenzira dzinowanzo shandiswa pakuita activation yesimbi tailings, mechanical grinding inogona kuderedza activation simba resimbi tailings uye kuburitsa mamwe mareti akaremara uye epurasitiki deformation.Tsvagiridzo iyi inoratidza kuti kukuya kwemuchina kunogona kumutsa chiitiko chepozzolanic cheyakajairwa mineral phases musimbi tailings.Sezvo saizi yemaminerari epasi inodzikira, quartz inogona kuita neCa (OH) 2 mune simende slurry kugadzira amorphous hydrated calcium silicate gel uye ettringite crystal uye zvimwe zvigadzirwa zvehydration.Tsvagiridzo inoratidza kuti kana iyo mechanic kugaya inopfuura 40min, iyo inopinza kona yesimbi tailings iri pachena yakaderedzwa, mamwe madiki madiki anoratidzwa, uye kufanana kunovandudzwa zvishoma nezvishoma.Mune anhydrite iron inotora calcium oxide system, iyo siliceous iron tailing yemakanika kugaya inogona kusanganiswa ne30% kugadzirira 32.5 simende.Pasi pemamiriro emvura yakaderera binder reshiyo, yakanaka iron tailings poda inogona kusimudzira zvakanyanya hydration yecomposite simende paste, kuita kuti pore chimiro chedhaka chiwedzere compact, uye kuvandudza simba rekutanga.Kuwedzera kwenzvimbo chaiyo yesimbi tailings haina mhedzisiro yakajeka pakuvandudza indekisi yayo yebasa;Shanduko yekupisa tembiricha inogona kuwedzera zvakanyanya indekisi yebasa padanho rekutanga (7d), asi ine mhedzisiro shoma pane indekisi yebasa panguva yekupedzisira (28d).Kune iyo iron tailings slag composite system, iyo indekisi yebasa inogona kuvandudzwa nekuvandudza nzira yekukuya, nekudaro ichivandudza kusimba kwekongiri.Iko kushandiswa zvine musoro kwemvura yekudzikisa mumiriri kunogona kuwedzera zvirimo zvesimbi tailings muyakajairika kongiri kubva pa30% kusvika 40%.Kukuya kwesimbi kunogona kuvandudza kushanda kwayo kuburikidza nekuita kwayo, nekudaro kunomutsa basa repozzolanic resimbi.Nekugadzirisa chiyero chesimbi tailings, slag, clinker uye gypsum composite cementitious zvinhu, Ultra-yakakwirira performance kongiri ine mashandiro inosangana neyakajairwa yenyika inogona kugadzirwa.
