Nickel isimbi yakakosha isina ferrous ine huwandu hwakawanda hwekushandisa. Inonyanya kuitika mu nickel sulfide uye nickel oxide ores mune zvakasikwa. 30% yezviwanikwa zvenickel ndeye sulfide ores uye 70% ndeye laterite nickel ores. Nekuwedzera kuri kuita nickel uye kuderera zvishoma nezvishoma kwe nickel sulfide ore, kuvandudzwa kwelateite nickel ore kunoratidza maitiro ane simba. Mukuita kwe sulfuric acid kuora kwe laterite nickel ore, tsvina yakasara ye laterite nickel ore yave chinhu chinotadzisa kunyorova nickel kutorwa. Somugadziri wenickel slagvertical grinding mill, HCMilling(Guilin Hongcheng) ichasuma nzira dzekudzoreredza uye kushandiswazve kwelatitic nickel ore waste slag kwauri pazasi.

Nzira yekudzoreredza uye kushandiswa zvakare kwelaititic nickel ore tsvina yakasara ndeye calcine latetitic nickel ore tsvina pa160 ~ 900 ℃ kwe20 ~ 120 min, uye mushure mekutonhodzwa kwechisikigo, ikuya muhupfu ine 0.08 mm yakasara kuburikidza nepasi pe10% nickel slagvertical grinding millkugadzirira raw material ye magnesium simenti, mugwagwa base kurapa zvinhu kana kuvaka madziro pendi putty. Matanho chaiwo ekudzoreredza uye kushandiswazve kwelateite nickel ore slag ndeaya anotevera:

(1) Iyo nickel slag ine hunyoro hwehuwandu hwe12% ~ 18% (yakanaka zvidimbu pazasi 3 mm account inodarika 70%, uye viscosity yakasimba) yakaomeswa neiyo inokurumidza kufashaidza yakaoma, iyo hunyoro inoderedzwa kusvika isingasviki 3%, uye yozoiswa mudura mushure mekurapwa kwesimbi yakawanda, uye zvinongedzo zvinoiswa mukati.nickel slagkugaya.

(2) Iyo yakaomeswa nickel slag inodyiswa mu nickel slag mill ye extrusion uye kupwanya mushure mekuputira (kuwedzera huwandu hwakakodzera hwe activator), uye zvino inoparadzaniswa nekuparadzaniswa kwemhepo. Zvimedu zvakakora zvinodzoserwa kunickel slagverticalrollerchigayo, uye hupfu hwakatsetseka hwakasara hunopinda muhupfu hwehupfu nemhepo kuti hugadzirire chigadzirwa chakapedzwa, icho chinozoiswa mukuchengetedza. Hupfu hwakakasharara hune nzvimbo chaiyo ye<200m2/kg hunodzoserwa kune nickel slag vertical grinding mill yobva yapwanywa. Imwe ultra-fine poda ine yakananga nzvimbo ye> 450m2/kg inounganidzwa nemuunganidzi weguruva yobva yatakurwa yakananga kunzvimbo yekuchengetera chigadzirwa.

Laterite nickel ore waste slag chaizvoizvo musanganiswa we calcium sulfate, magnesium hydroxide, calcium silicate hydrate uye calcium aluminate hydrate. Mushure mekuoma kana kuderera kwekushisa calcination, musanganiswa weanhydrous calcium sulfate, magnesium oxide, dicalcium silicate uye calcium aluminate inowanikwa. Iyo ine maitiro akajairwa ePortland simende, magnesite simende uye gypsum. Irwo rudzi rutsva rwesimende zvinhu uye runoshandiswa zvakanyanya muindasitiri yekuvaka. Kudzoreredza uye kushandisazve maitiro e laterite nickel ore waste slag iri nyore, haisanganisi tembiricha yakakwira, kumanikidza kwakanyanya uye zvinhu zvinodhura, uye zviri nyore kuita. Nzira yenickel slagverticalrollerchigayondiyo nhanho inonyanya kukosha mukugadzirisa, kushandiswa zvakare uye kushandiswa kwezviwanikwa zve laterite nickel slag, kuverenga kwehafu yesimba rose rekushandisa, kuitira kuderedza mari yekugadzira, kushandiswa kwesimba uye kuvandudza kushanda kwe nickel slag grinding. Isu tinokurudzira kuti usarudze nickel ore vertical grinding mill kuti utsive chigayo chebhora sechigayo chikuru chekudzoreredza uye kushandisa zvakare laterite nickel ore slag. Thenickel slag ultra-finechigayoprocess ye nickel slagvertical grinding mill inogamuchirwa, uye hunyoro hwakakodzera hwekukuya hunowanikwa nekugadzirisa zvinonzwisisika mugadziri kuti ave nechokwadi chekugadzirwa kwehupfu hwakatsetseka hune nzvimbo chaiyo inosangana nesimba uye basa rinodiwa pasi pekushandiswa kwesimba rakaderera, kuitira kudzivirira dambudziko rehuwandu hwehupfu hwehupfu kana kushandiswa kwesimba kwakanyanya kunokonzerwa nekunyanya-kugaya chiitiko chetsika bhora kugaya.

HLM yakatevedzana nickel slagvertical grinding mill inogadzirwa neHCMilling(Guilin Hongcheng) yakashandiswa zvakanyanya mumhando dzakasiyana dzemarara slag kudzokorodza uye kudzokorodza kugadzira zvigadzirwa zvesimende zvakasvibirira, zvichipa tsigiro yemidziyo yakanaka yekudzoreredza uye kushandiswazve kwelaite nickel ore waste slag. Kana iwe uine kudiwa kwe laterite nickel ore tsvina yekudzokorodza uye nickel slagkugaya, ndapota taura neHCM kuti uwane ruzivo rwemidziyo.
