Cov pob zeb tailings raug tsim tawm hauv cov txheej txheem beneficiation. Vim tias cov ore qib qis, muaj ntau cov pob zeb tailings raug tsim tawm hauv cov txheej txheem beneficiation, suav txog li 90% ntawm cov ore nyoos. Tus naj npawb ntawm cov pob zeb tailings hauv Suav teb yog loj heev, thiab feem ntau ntawm lawv tsis siv tau zoo. Lawv feem ntau khaws cia rau hauv cov pas dej tailings lossis cov chaw pov tseg, ua rau pov tseg cov peev txheej. Kev sib sau ua ke ntawm cov pob zeb tailings tsis yog tsuas yog siv ntau cov peev txheej hauv av xwb, tab sis kuj ua rau ib puag ncig tsis huv thiab cuam tshuam rau tib neeg txoj kev noj qab haus huv. Yog li ntawd, kev siv cov pob zeb tailings tag nrho yog qhov teeb meem ceev ceev uas yuav tsum tau daws hauv kev lag luam mining hauv Suav teb. HCMilling (Guilin Hongcheng), ua tus tsim khoom ntawm cov khoom seemntsug roller zeb, yuav qhia txog txoj kev npaj cov cement clinker los ntawm cov tailings.

Cov zaub mov tseem ceeb hauv cov sulphoaluminate cement clinker yog calcium sulphoaluminate thiab dicalcium silicate (C2S). Cov khoom siv raw calcium, silica, txhuas thiab sulfur yog qhov xav tau hauv cov txheej txheem npaj. Vim tias sulphoaluminate cement clinker muaj ntau yam khoom siv thiab tsis tas yuav tsum tau qib, cov khib nyiab khov kho tuaj yeem siv los hloov qee cov khoom siv raw. Cov khoom siv tshuaj lom neeg tseem ceeb ntawm cov tailings suav nrog SiO2, Fe2O3, Al2O3, CaF2, thiab lwm yam, nrog rau me ntsis W, Mo, Bi thiab lwm yam kab kawm. Vim tias cov khoom siv tshuaj lom neeg ntawm cov tailings zoo ib yam li cov khoom siv raw silica siv los npaj sulphoaluminate cement clinker, cov tailings tuaj yeem siv los hloov cov khoom siv raw silica, uas tsis tsuas yog txuag cov peev txheej av, tab sis kuj tiv thaiv ib puag ncig. CaF2 hauv tungsten tailings yog cov mineralizer zoo heev, uas tuaj yeem txhawb kev tsim ntau yam zaub mov hauv clinker thiab txo qhov kub sintering ntawm clinker. Tib lub sijhawm, cov cement clinker tuaj yeem daws Ti hauv titanium gypsum thiab W, Mo, Bi thiab lwm yam kab hauv tungsten tailings. Qee cov ntsiab lus tuaj yeem nkag mus rau hauv lub lattice siv lead ua ntawm cov mineral. Vim tias lub vojvoog ntawm cov ntsiab lus nkag mus txawv ntawm cov ntsiab lus lattice thawj, cov kev teeb tsa lattice yuav hloov pauv, ua rau muaj kev cuam tshuam lattice, Nws tuaj yeem txhim kho kev ua haujlwm ntawm cov minerals thiab hloov cov khoom ntawm clinker.

Txoj kev npaj cov cement clinker los ntawm cov tailings: siv cov tailings los hloov cov khoom siv siliceous siv rau hauv kev tsim cov sulphoaluminate cement clinker, thiab hloov ib feem ntawm cov khoom siv aluminium raw. Tom qab sib tsoo rau qee qhov fineness, tswj kev tsim cov cement clinker thiab C2S minerals los ntawm alkalinity coefficient Cm thiab sulfur aluminium piv P, thiab npaj sulphoaluminate cement clinker nrog aluminium tshauv, calcium carbide slag, titanium gypsum thiab lwm yam khoom xyaw. Cov kauj ruam yog raws li nram no: tailings, aluminium tshauv, carbide slag thiab titanium gypsum yog sib tsoo rau tsawg dua 200 meshes; Ntsuas txhua yam khoom siv raw raws li cov khoom siv raw piv, sib tov thiab do kom sib npaug, nias cov khoom sib tov rau hauv lub ncuav mog qab zib sim nrog lub ntsiav tshuaj nias, thiab ziab nws rau 10h ~ 12h ntawm 100 ℃ ~ 105 ℃ rau standby; Lub ncuav mog qab zib sim npaj tau muab tso rau hauv lub cub tawg kub, cua sov rau 1260 ℃.～1300 ℃, khaws cia rau 40～55 feeb, thiab quenched rau chav tsev kub kom tau txais tungsten tailings sulphoaluminate cement clinker. Ntawm lawv, kev siv tailings ntsuglub tshuab zeb rau kev sib tsoo yog cov kauj ruam tseem ceeb.

HCMilling (Guilin Hongcheng) yog cov chaw tsim khoom ntawm tailing ntsug roller mill. PebHLM series tailingntsug roller zebtuaj yeem sib tsoo 80-600 mesh tailing hmoov, muab kev txhawb nqa zoo rau txoj kev npaj cement clinker los ntawm tailing. Yog tias koj muaj cov kev xav tau yuav khoom, thov hu rau HCM kom paub meej ntxiv txog cov khoom siv.
