Nickel yog ib qho hlau tseem ceeb uas tsis yog ferrous uas muaj ntau yam kev siv. Nws feem ntau tshwm sim hauv nickel sulfide thiab nickel oxide ores hauv xwm. 30% ntawm cov peev txheej nickel yog sulfide ores thiab 70% yog laterite nickel ores. Nrog rau kev thov nickel ntau ntxiv thiab kev maj mam ploj ntawm nickel sulfide ore, kev txhim kho ntawm laterite nickel ore qhia txog kev sib hloov pauv. Hauv cov txheej txheem ntawm sulfuric acid decomposition ntawm laterite nickel ore, cov khib nyiab ntawm laterite nickel ore tau dhau los ua ib qho tseem ceeb uas txwv tsis pub cov txheej txheem rho tawm nickel ntub. Raws li tus neeg tsim khoom ntawmnickel slagzeb sib tsoo ntsug, HCMilling (Guilin Hongcheng) yuav qhia koj txog cov txheej txheem ntawm kev rov qab thiab rov siv dua cov khib nyiab lateritic nickel ore rau hauv qab no.

Txoj kev rov qab thiab siv cov khib nyiab lateritic nickel ore yog calcine lateritic nickel ore khib nyiab ntawm 160 ~ 900 ℃ rau 20 ~ 120 feeb, thiab tom qab txias ntuj, zom nws rau hauv cov khoom siv hmoov nrog 0.08 hli sieve residue tsawg dua 10% los ntawm nickel slagzeb sib tsoo ntsuglos npaj cov khoom siv raw ntawm magnesium cement, cov khoom siv kho txoj kev lossis cov xim pleev phab ntsa. Cov kauj ruam tshwj xeeb rau kev rov qab thiab siv cov laterite nickel ore slag yog raws li nram no:

(1) Cov nickel slag nrog cov dej noo ntawm 12% ~ 18% (cov khoom me me hauv qab 3 hli suav rau ntau dua 70%, thiab viscosity yog muaj zog) yog ziab los ntawm lub tshuab ziab sai, cov dej noo raug txo kom tsawg dua 3%, thiab tom qab ntawd nws raug muab tso rau hauv qhov chaw cia khoom tom qab kev kho mob tshem tawm hlau ntau theem, thiab cov khoom xyaw raug muab tso rau hauvnickel slaglub tshuab sib tsoo.

(2) Cov nickel slag qhuav raug pub rau hauv lub tshuab nickel slag rau extrusion thiab crushing tom qab batching (ntxiv ib qho nyiaj tsim nyog ntawm activator), thiab tom qab ntawd sib cais los ntawm kev sib cais huab cua. Cov khoom me me raug xa rov qab mus raunickel slagntsuglub menyuamlub zeb, thiab cov hmoov zoo seem nkag mus rau hauv lub tshuab ua hmoov nrog cua los npaj cov khoom tiav, uas tom qab ntawd muab tso rau hauv qhov chaw khaws cia. Cov hmoov ntxhib nrog thaj chaw tshwj xeeb ntawm <200m2 / kg raug xa rov qab mus rau lub tshuab sib tsoo nickel slag ntsug thiab tom qab ntawd tsoo. Qee cov hmoov zoo heev nrog thaj chaw tshwj xeeb ntawm> 450m2 / kg raug sau los ntawm lub tshuab sau hmoov av thiab tom qab ntawd thauj mus rau lub tsev rau khoom tiav.

Cov pob zeb laterite nickel ore pov tseg yog qhov sib xyaw ntawm calcium sulfate, magnesium hydroxide, calcium silicate hydrate thiab calcium aluminate hydrate. Tom qab ziab lossis calcination kub qis, cov sib xyaw ntawm anhydrous calcium sulfate, magnesium oxide, dicalcium silicate thiab calcium aluminate tau txais. Nws muaj cov yam ntxwv zoo ib yam li Portland cement, magnesite cement thiab gypsum. Nws yog ib hom cementitious tshiab thiab muaj kev siv dav hauv kev lag luam kev tsim kho. Cov txheej txheem rov qab thiab rov siv dua ntawm laterite nickel ore pov tseg slag yog yooj yim, tsis muaj kev kub siab, siab siab thiab cov ntaub ntawv kim, thiab yooj yim rau kev siv. Cov txheej txheem ntawmnickel slagntsuglub menyuamlub zebyog kauj ruam tseem ceeb tshaj plaws hauv kev rov qab, rov siv dua thiab siv cov peev txheej ntawm laterite nickel slag, suav txog li ib nrab ntawm tag nrho cov kev siv hluav taws xob, txhawm rau txo cov nqi tsim khoom, kev siv hluav taws xob thiab txhim kho kev ua haujlwm ntawm nickel slag sib tsoo. Peb xav kom koj xaiv lub tshuab sib tsoo nickel ore ntsug los hloov lub tshuab pob zeb ib txwm ua cov khoom siv tseem ceeb rau kev rov qab thiab rov siv dua ntawm laterite nickel ore slag. Lubnickel slag zoo heevlub zebtxheej txheem ntawm nickel slagzeb sib tsoo ntsug tau txais yuav, thiab qhov kev sib tsoo zoo tsim nyog tau ua tiav los ntawm kev kho qhov classifier kom tsim nyog kom ntseeg tau tias cov hmoov zoo heev nrog thaj chaw tshwj xeeb ua tau raws li lub zog thiab kev ua haujlwm xav tau hauv qab kev siv hluav taws xob tsawg, yog li kom tsis txhob muaj teeb meem ntawm cov hmoov zoo ntau dhau lossis kev siv hluav taws xob ntau dhau los ntawm qhov xwm txheej sib tsoo ntau dhau ntawm kev sib tsoo pob ib txwm muaj.

HLM series nickel slagzeb sib tsoo ntsug tsim los ntawm HCMilling (Guilin Hongcheng) tau siv dav hauv ntau hom kev siv rov qab thiab rov ua dua cov khib nyiab slag los tsim cov khoom siv cementitious ntsuab, muab kev txhawb nqa cov khoom siv zoo rau kev rov qab thiab rov siv dua ntawm laterite nickel ore pov tseg slag. Yog tias koj muaj qhov xav tau rau laterite nickel ore pov tseg rov ua dua thiab nickel slaglub tshuab sib tsoo, thov hu rau HCM kom paub meej txog cov khoom siv.
