Calcium oxide, nrog rau cov tshuaj formula CaO, yog tsim los ntawm thermally decomposing limestone los yog plhaub uas muaj calcium carbonate los ntawm cua sov rau saum 825 degrees Celsius nyob rau hauv ib tug txiv qaub kiln. Cov txheej txheem no, hu ua calcination los yog txiv qaub burning, tso carbon dioxide, tawm hauv quicklime. Quicklime tsis ruaj tsis khov thiab tshwj tsis yog tias slaked nrog dej los ua cov kua txiv qaub los yog txiv qaub mortar, nws yuav tshwm sim nrog CO2 nyob rau hauv cov huab cua thaum nws txias, nws thiaj li hloov tag nrho rov qab rau hauv calcium carbonate.

Kev siv cov calcium oxide

Calcium oxide muaj ntau yam kev siv hauv ntau lub teb vim nws muaj ntau yam. Hauv kev tsim kho, calcium oxide tuaj yeem siv los ua cov khoom siv hauv tsev los txhim kho qhov teeb tsa sai ntawm cov cement. Hauv cov txheej txheem metallurgical, nws ua raws li cov flux los pab yaj cov hlau. Hauv kev ua cov roj zaub, calcium oxide ua tus neeg sawv cev decolorizing los txhim kho cov khoom roj zoo. Tsis tas li ntawd, nws tseem tuaj yeem siv rau kev txhim kho cov av kom cov av fertility, ua cov khoom siv tshuaj los txhim kho kev ruaj ntseg thiab bioavailability ntawm cov tshuaj, thiab ua cov calcium chiv los txhawb cov nroj tsuag kev loj hlob.

Calcium oxide kuj tseem siv los ua cov ntaub ntawv refractory los txhim kho qhov kub thiab txias ntawm cov ntaub ntawv. Raws li tus desiccant, nws tuaj yeem nqus dej noo hauv huab cua thiab khaws cov khoom kom qhuav. Hauv kev kho dej khib nyiab, calcium oxide yog siv los kho cov dej khib nyiab acidic thiab sludge conditioning kom huv dej kom zoo. Tsis tas li ntawd, nws kuj yog siv los ua cov tshuaj xws li calcium carbide, soda tshauv, thiab tshuaj dawb huv.

Calcium oxide processing ntws

Kev ua haujlwm ntawm calcium oxide feem ntau suav nrog calcination ntawm limestone thiab kev sib tsoo ntawm calcium oxide. Tom qab lub limestone yog crushed thiab soj ntsuam, nws raug xa mus rau lub txiv qaub kiln rau calcination. Ntawm qhov kub ntawm 900 txog 1200 degrees Celsius, limestone decomposes tsim calcium oxide thiab carbon dioxide. Tom qab cov calcined calcium oxide txias thiab crushed, cov khoom ua ntej calcium oxide tuaj yeem tau. Txhawm rau kom tau txais cov hmoov calcium oxide zoo dua, cov khoom siv ua hmoov yuav tsum tau ua. 200 mesh calcium oxide hmoov ua tshuab ua lub luag haujlwm tseem ceeb hauv qhov txuas no. Cov cuab yeej no tuaj yeem zom cov calcium oxide ntxiv rau hauv 200 mesh hmoov zoo kom tau raws li ntau yam kev xav tau.

200 mesh calcium oxide hmoov ua tshuab qhia

200 mesh calcium oxide hmoov ua tshuab yog cov kws tshaj lij calcium oxide hmoov sib tsoo cov cuab yeej tsim los ntawm Guilin Hongcheng Mining Equipment Manufacturing Co., Ltd. Nws tuaj yeem zom cov calcium oxide zoo rau hauv 200 mesh hmoov zoo, thiab tuaj yeem kho cov khoom loj ntawm 80 mesh mus rau 400 mesh raws li qhov xav tau tiag tiag. Cov khoom siv tuaj yeem ua kom muaj peev xwm ntau dua 40% thiab txo cov nqi siv hluav taws xob ntau dua 30%. Nws muaj suab nrov tsawg, kev faib ua haujlwm siab, muaj peev xwm thauj khoom loj thiab kev faib tawm siab. Nws yog ib qho zoo tagnrho tshiab ib puag ncig tus phooj ywg suab nrov txo kev sib tsoo khoom. Nyob rau tib lub sijhawm, cov cuab yeej tau nruab nrog cov motors siab heev thiab kev tswj hwm, uas tuaj yeem paub txog kev tsim khoom siv hluav taws xob thiab txhim kho kev tsim khoom.

Guilin Hongcheng 200 mesh calcium oxide hmoovua tshuab plays lub luag haujlwm tseem ceeb hauv kev ua cov calcium oxide. Los ntawm kev sib tsoo zoo, nws tuaj yeem zom cov calcium oxide rau hauv 200 mesh hmoov zoo kom tau raws li ntau yam kev thov. Yog xav paub ntxiv cov kev ntsuas thiab cov lus tshaj tawm ntawm cov cuab yeej no, thov hu rau peb kom paub meej.
