Nickel isimbi inokosha isina ferrous ine mashandisirwo akasiyana-siyana. Inonyanya kuwanikwa mu nickel sulfide uye nickel oxide ores. 30% yezviwanikwa zve nickel i sulfide ores uye 70% i laterite nickel ores. Nekuwedzera kwekuda kwe nickel uye kupera zvishoma nezvishoma kwe nickel sulfide ore, kukura kwe laterite nickel ore kunoratidza maitiro akasimba. Mukuita kwekuora kwe sulfuric acid ye laterite nickel ore, marara e laterite nickel ore ave chinhu chinodzivisa maitiro ekubvisa nickel yakanyorova. Semugadziri wenickel slagchigayo chekukuya chakamira, HCMilling (Guilin Hongcheng) ichakuzivisai nzira dzekudzoreredza nekushandisazve marara e lateritic nickel ore.

Nzira yekudzoreredza nekushandisazve marara e lateritic nickel ore ndeyekukanda marara e lateritic nickel ore residue pa 160~900 ℃ kwemaminitsi 20~120, uye mushure mekutonhorera kwechisikigo, pwanya kuita upfu ne 0.08 mm sieve residue pasi pe 10% kuburikidza. nickel slagchigayo chekukuya chakamirakugadzira zvinhu zvakagadzirwa nesimende yemagnesium, zvinhu zvinogadzirisa mugwagwa kana putty yependi yekuvaka pamadziro. Matanho chaiwo ekudzoreredza nekushandisazve laterite nickel ore slag ndeaya anotevera:

(1) Nickel slag ine hunyoro hwe12% ~ 18% (zvidimbu zvidiki zviri pasi pe3 mm zvinopfuura 70%, uye viscosity yakasimba) inoomeswa nemuchina wekuomesa unokurumidza kufashaira, hunyoro hunoderedzwa kusvika pasi pe3%, uye inobva yaiswa mudura mushure mekubvisa simbi mumatanho akawanda, uye zvinoshandiswa zvinoiswa mudura.nickel slagchigayo chekukuya.

(2) Nickel slag yakaomeswa inoiswa munickel slag mill kuti ibudiswe uye ipwanywe mushure mekusanganiswa (kuwedzera huwandu hwakakodzera hweactivator), uye yobva yaparadzaniswa nekuparadzaniswa kwemhepo. Zvidimbu zvakakora zvinodzoserwa kunickel slagyakatwasukachinotendererachigayo, uye hupfu hwakatsetseka hwasara hunopinda mupombi inosanganisa hupfu nemhepo kuti hugadzirire chigadzirwa chapera, icho chinozoiswa mudura. Hupfu hwakatsetseka hune nzvimbo yakatarwa ye<200m2/kg hunodzoserwa ku nickel slag vertical grinding mill hwobva hwapwanywa. Humwe hupfu hwakatsetseka kwazvo hune nzvimbo yakatarwa ye>450m2/kg hunounganidzwa nemuchina wekuunganidza guruva uye hwozoendeswa zvakananga kuchitoro chezvigadzirwa zvapera.

Laterite nickel ore waste slag chaizvoizvo musanganiswa wecalcium sulfate, magnesium hydroxide, calcium silicate hydrate uye calcium aluminate hydrate. Mushure mekuomeswa kana kupiswa nekupisa kwakaderera, musanganiswa weanhydrous calcium sulfate, magnesium oxide, dicalcium silicate uye calcium aluminate unowanikwa. Une hunhu hwakafanana nePortland cement, magnesite cement uye gypsum. Imhando itsva yezvinhu zvinosimbisa uye zvinoshandiswa zvakanyanya muindasitiri yekuvaka. Maitiro ekudzoreredza uye kushandisazve laterite nickel ore waste slag ari nyore, haabatanidzi kupisa kwakanyanya, kumanikidzwa kwakanyanya uye zvinhu zvinodhura, uye zviri nyore kuita. Maitiro enickel slagyakatwasukachinotendererachigayoNdiyo nhanho inonyanya kukosha mukugadzirisa, kushandisazve uye kushandisa zviwanikwa zve laterite nickel slag, zvichiita kuti pave nehafu yesimba rese rinoshandiswa, kuitira kuderedza mari yekugadzira, kushandisa simba uye kuvandudza kushanda zvakanaka kwe nickel slag grinding. Tinokurudzira kuti usarudze nickel ore vertical grinding mill kutsiva bhora rekare sechishandiso chikuru chekudzoreredza uye kushandisazve laterite nickel ore slag.nickel slag zvakanaka kwazvochigayomaitiro e nickel slagchigayo chekukuya chakamira yatorwa, uye kutsetseka kwakakodzera kwekukuya kunowanikwa nekugadzirisa zvine musoro muchina wekusarudza kuti ive nechokwadi chekuti upfu hwakatsetseka hwakanyanya hunosangana nezvinodiwa nesimba uye mashandiro pasi pesimba shoma, kuitira kudzivirira dambudziko rehuwandu hwakawanda hweupfu hwakatsetseka kana kushandiswa kwesimba rakawanda kunokonzerwa nekukwesha zvakanyanya kwekugaya bhora kwechinyakare.

HLM dzakatevedzana nickel slagchigayo chekukuya chakamira yakagadzirwa neHCMilling (Guilin Hongcheng) yakashandiswa zvakanyanya mumhando dzakasiyana dzemarara ekudzokorodza nekudzokorodza kugadzira zvinhu zvegirini zvinosimbisa simende, zvichipa rutsigiro rwakanaka rwemidziyo yekudzokorodza nekudzokorodza marara e laterite nickel ore. Kana uchida marara e laterite nickel ore ekudzokorodza uye nickel slagchigayo chekukuya, ndapota taura neHCM kuti uwane rumwe ruzivo nezvemichina.
