Tailings yog tsim nyob rau hauv txoj kev pab.Vim tias qib qis ore, ntau cov tailings yog tsim nyob rau hauv cov txheej txheem tau txais txiaj ntsig, suav txog li 90% ntawm cov ore raw.Tus naj npawb ntawm tailings nyob rau hauv Tuam Tshoj yog loj, thiab feem ntau ntawm lawv tsis zoo siv.Lawv tsuas yog khaws cia rau hauv cov pas dej tailings los yog landfill mines, ua rau cov khoom siv pov tseg.Kev sib sau loj ntawm cov tailings tsis tsuas yog siv ntau thaj av, tab sis kuj ua rau ib puag ncig thiab cuam tshuam rau tib neeg txoj kev noj qab haus huv.Yog li ntawd, kev siv dav dav ntawm tailings yog ib qho teeb meem ceev uas yuav tsum tau daws nyob rau hauv Tuam Tshoj txoj kev lag luam mining.HCMilling (Guilin Hongcheng), ua cov chaw tsim khoom ntawm tailingsntsug roller mills, yuav qhia cov txheej txheem ntawm kev npaj cov cement clinker los ntawm tailings.
Cov zaub mov tseem ceeb hauv sulphoaluminate cement clinker yog calcium sulphoaluminate thiab dicalcium silicate (C2S).Calcium, silica, aluminium thiab sulfur raw cov ntaub ntawv yuav tsum tau nyob rau hauv cov txheej txheem npaj.Raws li cov sulphoaluminate cement clinker muaj ntau yam khoom siv thiab cov kev xav tau qis rau qib, cov khoom pov tseg tuaj yeem tsim nyog siv los hloov qee cov ntaub ntawv raw.Cov tshuaj lom neeg tseem ceeb ntawm tailings muaj xws li SiO2, Fe2O3, Al2O3, CaF2, thiab lwm yam, nrog rau ib qho me me ntawm 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 ntawm silica raw cov ntaub ntawv siv los npaj sulphoaluminate cement clinker, tailings tuaj yeem siv los hloov silica raw cov ntaub ntawv, uas tsis tsuas yog txuag av, tab sis kuj tiv thaiv ib puag ncig.CaF2 nyob rau hauv tungsten tailings yog ib tug zoo mineralizer, uas yuav txhawb kev tsim ntawm ntau yam minerals nyob rau hauv lub clinker thiab txo qhov kub ntawm 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 lub ntsiab lus tuaj yeem nkag mus rau hauv cov khoom siv lead ua lattice ntawm cov ntxhia.Vim hais tias lub vojvoog ntawm cov khoom nkag yog txawv ntawm cov thawj lattice ntsiab, lub lattice tsis yuav hloov, ua rau lattice distortion, Nws tuaj yeem txhim kho cov haujlwm ntawm cov ntxhia thiab hloov cov khoom ntawm clinker.
Cov txheej txheem ntawm kev npaj cov cement clinker los ntawm tailings: siv tailings los hloov cov ntaub ntawv raw khoom siv hauv kev tsim cov pa sulphoaluminate cement clinker, thiab ib nrab hloov cov ntaub ntawv raw khoom.Tom qab sib tsoo kom zoo, tswj kev tsim cov cement clinker thiab C2S cov zaub mov los ntawm alkalinity coefficient Cm thiab sulfur aluminium ratio P, thiab npaj sulphoaluminate cement clinker nrog txhuas 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 feem ntau hauv av kom tsawg dua 200 meshes;Ntsuas txhua yam khoom siv raw khoom raws li cov khoom siv raw, sib tov thiab sib tov sib xyaw, nias qhov sib tov rau hauv lub khob noom cookie nrog cov ntsiav tshuaj xovxwm, thiab qhuav rau 10h ~ 12h ntawm 100 ℃ ~ 105 ℃ rau standby;Lub khob noom cookie tau npaj tau muab tso rau hauv qhov cub kub kub, rhuab mus rau 1260 ℃~1300 ℃, khaws cia rau 40~55min, thiab quenched rau chav tsev kub kom tau tungsten tailings sulphoaluminate cement clinker.Ntawm lawv, kev siv tailings ntsugroller zeb rau kev sib tsoo yog cov txheej txheem tseem ceeb.
HCMilling (Guilin Hongcheng) yog cov chaw tsim khoom ntawm tailing ntsug cov menyuam zeb.PebHLM series tailingntsug roller millstuaj yeem zom 80-600 mesh tailing hmoov, muab cov cuab yeej zoo txhawb rau txoj kev npaj cov cement clinker los ntawm tailing.Yog tias koj muaj cov cai yuav khoom, thov hu rau HCM kom paub meej cov khoom siv.
