Xyoo 2015, tus tsim khoom Cui Weihua tau tshaj tawm daim ntawv pov thawj patent: ib txoj kev rau kev npaj cov calcium carbonate uas muaj cov khoom siv siab thiab huv los ntawm cov hlau slag. Puas yog nws ua tau los ua cov calcium carbonate uas muaj cov khoom siv siab thiab huv los ntawm cov hlau slag siv hlau slag ntsug roller zeb?

Raws li Tuam Tshoj Powder Technology Network, tsis ntev los no, "100000 ton carbonization method iron and steel slag comprehensive utilization industrialization demonstration line", ib qho project cog lus ntawm "rejuvenating Mongolia los ntawm kev tshawb fawb thiab thev naus laus zis", tau pib hauv Baotou. Qhov project no tau tsim los ntawm Baotou Steel Group thiab Yukuang Environmental Protection Technology (Shanghai) Co., Ltd. Nws tau tshaj tawm tias qhov project no yog raws li cov txiaj ntsig ntawm "10,000 ton verification production line rau kev siv tag nrho ntawm steel slag los ntawm carbonization method". Cov steel slag yog carbonized tag nrho, thiab thaum kawg tsim cov khoom lag luam xws li cov khoom siv calcium carbonate thiab hlau uas muaj cov khoom siv, kom paub txog kev siv cov peev txheej ntawm steel slag. Piv nrog rau cov thev naus laus zis ib txwm muaj, cov thev naus laus zis carbonization iron and steel slag kho tshuab tuaj yeem siv carbon dioxide ua cov khoom siv raw los koom nrog hauv kev tshuaj tiv thaiv thaum txo cov pa roj carbon dioxide, uas muaj ob qho txiaj ntsig carbon txo qis, ua tiav lub hom phiaj ntawm kev txo cov pa roj av thiab txhawb kev txhim kho ntawm cov pa roj carbon tsawg. Tom qab ua tiav qhov project, 424000 tons ntawm cov hlau slag tuaj yeem kho tau txhua xyoo, thaum kwv yees li 100000 tons ntawm cov pa roj carbon dioxide tuaj yeem carbonized (kaw), thiab muaj peev xwm tsim tau 200000 tons ntawm cov calcium carbonate siab-purity thiab 310000 tons ntawm cov khoom siv hlau tuaj yeem ua tiav. Qhov project no yog kev tshawb nrhiav kev lag luam ntxiv, uas tuaj yeem txhawb nqa dav hauv cov lag luam zoo sib xws. Thaum ua tau raws li qhov xav tau rau kev siv cov khib nyiab khov kho, nws yog qhov zoo rau kev ua tiav lub hom phiaj ntawm cov pa roj carbon siab thiab cov pa roj carbon neutralization. Qhov no txhais tau tias qhov ua tau ntawm qhov project ntawm kev tsim cov calcium carbonate siab-purity los ntawm cov hlau slag. Nws kuj muab txoj hauv kev tshiab rau kev siv cov khib nyiab khov kho steel slag tag nrho.

Cov yam ntxwv tseem ceeb ntawm kev tsim cov calcium carbonate uas muaj cov khoom siv siab heev los ntawm cov hlau slag yog raws li nram no: ua ntej, zom cov hlau slag ua hmoov, tso cov calcium oxide dawb hauv cov hlau slag rau saum npoo ntawm cov hlau slag, rho tawm cov calcium oxide hauv cov hlau slag los ntawm txoj kev ntub dej nrog 0.5% acetic acid, lim thiab ua kom meej, tom qab ntawd carbonize nws nrog cov pa roj carbon dioxide, thiab tom qab ntawd dehydrate, ntxuav, qhuav, txias, tsoo thiab tshuaj ntsuam nws kom tsim cov calcium carbonate uas muaj cov khoom siv siab heev. Cov calcium carbonate uas muaj cov khoom siv siab heev yog siv dav ua cov khoom siv rau cov vuas pem teb dag, roj hmab, yas, ua ntawv, txheej, xim, kua mem, cables, khoom siv hauv tsev, khoom noj, tshuaj, textiles, pub, tshuaj txhuam hniav thiab lwm yam khoom. Hauv cov txheej txheem no, qhov sib tsoo zoo ntawm cov hlau slag yuav tsum ncav cuag ntau dua 400 meshes. Cov khoom siv hom twg tuaj yeem siv los ua tiav kev tsim cov hmoov hlau slag me me loj? Ua tus kws tshaj lij tsim khoom ntawmhlauslag sib tsoo zeb, HCMilling (Guilin Hongcheng) pom zoo kom koj xaivHLM steel slagntsug roller zeb rau kev tsim cov hmoov hlau slag. Tam sim no, cov txheej txheem kho cov hmoov hlau slag ntawm kev ua lag luam feem ntau yog ua ntej sib tsoo + sib tsoo zoo. Cov hlau slag tuaj yeem sib tsoo rau ntau dua 420 microns tom qab sib tsoo ob theem. Tus nqi khoom siv, thaj chaw hauv pem teb thiab kev siv hluav taws xob nruab nrab yog cov peev txheej loj heev.

HCMilling (Guilin Hongcheng) pab pawg R&D thiab cov kws tshaj lij hauv kev lag luam, los ntawm kev koom tes tob thiab kev sim, tau tshaj tawm qhovHLM series steel slagntsug roller zeb, uas tuaj yeem zom cov hmoov hlau slag ua cov duab tib lub sijhawm, txhim kho qhov siv ntawm cov hmoov hlau slag, thiab qhib kev lag luam daim ntawv thov downstream. Nws yog cov khoom siv hmoov hlau slag micro zoo tagnrho los txuag nqi, kev siv hluav taws xob, thaj chaw hauv pem teb, cov txiaj ntsig thiab cov nqi ntxiv ntawm cov khoom tiav.

Yog tias koj muaj qhov xav tau rau kev tsim thiab ua cov hmoov hlau slag, thov hu rau peb kom paub meej ntxiv thiab muab cov ntaub ntawv hauv qab no rau peb:
