Limestone yog cov pob zeb sedimentary, feem ntau yog tsim los ntawm calcium carbonate thiab magnesium carbonate.Nws lub hom phiaj tseem ceeb yog ua cov xuab zeb sib sau ua ke.Pob zeb chips thiab pob zeb hmoov ua nyob rau hauv cov txheej txheem ntawm kev ua thiab ntau lawm ua limestone tailings.Limestone tailings yog hauv av rau limestone hmoov los ntawmlimestone sib tsoo zeb.Nws tuaj yeem siv los ua cov khoom sib xyaw ua ke thiab cov pob zeb ua vaj tse prefabricated kom siv tau cov pob zeb ua kom zoo tshaj plaws.Raws li ib tug manufacturers ntawm limestonesib tsoo zebtshuab, HCMilling (Guilin Hongcheng) yuav qhia txog daim ntawv thov ntawmlimestonesib tsoo zeb tshuab ua cov limestone hmoov.

Limestone ntxhia hmoov yog hais txog cov hmoov nplej uas muaj qhov me me tsawg dua 0.075mm (txhais tau nyob rau hauv hydraulic pob zeb nrog particle loj tsawg dua 0.16mm) ua thaum lub sij hawm ua cov xuab zeb aggregate.Cov kev siv tseem ceeb yog:

(1) Limestone hauv av rau hauv cov hmoov ntxhia ua pob zeb sib xyaw: Daim ntawv thov ntawm limestone ntxhia hmoov hauv kev lag luam pob zeb tau kawm ntev.Raws li lub ntsiab lus tseem ceeb ntawm tailings, yuav ua li cas siv limestone ore hmoov raws li cov khoom sib xyaw ua ke tau dhau los ua qhov chaw kub thiab kev txhim kho hauv kev lag luam hauv tsev.Limestone hmoov yog ib qho inert admixture.Raws li kev sib xyaw ua ke rau pob zeb, limestone hmoov muaj qhov zoo thiab qhov ua tau zoo: ua ntej, qhov sib ntxiv ntawm limestone hmoov tuaj yeem ua kom cov dej ntawm cov cement;Qhov thib ob yog tias cov khoom ntawm limestone ore hmoov muaj cov nyhuv zoo thiab cov nyhuv filling.Nws tuaj yeem tsis tsuas yog ua kom cov kua dej sib xyaw ua ke, txhim kho cov khoom sib xyaw ntawm cov khoom siv cementitious, tab sis kuj txhim kho lub pore qauv ntawm cov pob zeb;Thib peb, limestone hmoov muaj cov nyhuv ua haujlwm.Nyob rau hauv xyoo tas los no, Tuam Tshoj tau ua tiav cov qauv hauv teb chaws thiab hauv zos, uas tau lees paub thiab ua qauv siv cov hmoov limestone los ua cov peev txheej.Raws li kev sib xyaw ua ke, limestone hauv av rau hauv cov hmoov ntxhia muaj kev lag luam dav thiab cov txiaj ntsig zoo hauv zej zog thiab kev lag luam hauv lub sijhawm ntev.

(2) Kev npaj prefabricated tivthaiv admixture los ntawm kev sib tsoo limestone rau hauv cov hmoov ntxhia: Cov txheej txheem prefabricated tshiab muaj qhov zoo ntawm kev siv ceev ceev, yooj yim tswj, khoom txuag, zoo li zoo, zoo durability, txo nyob rau hauv qhov chaw ntub dej, thiab kev tiv thaiv ib puag ncig.Nyob rau hauv lub tshav pob ntawm prefabricated Cheebtsam, ib tug loj npaum li cas ntawm limestone ntxhia hmoov nyob rau hauv limestone tailings kuj yuav siv tau raws li pob zeb thiab cement admixtures.Tus Qauv rau Kev Tswj Xyuas Zoo ntawm Precast Concrete Cheebtsam (DB11/T1312-2015) xav kom thaum xaiv cov ntxhia ntxiv xws li limestone ntxhia hmoov rau cov pob zeb ua ntej, nws qhov kev ua tau zoo yuav tsum ua tau raws li cov qauv tsim nyog.Qee cov kev tshawb fawb tau pom tias cov hmoov limestone tuaj yeem txhim kho cov dej ntws zoo thiab tiv thaiv kev sib cais ntawm cov pob zeb hauv kev tsim cov khoom tsis muaj kev vibration thiab nws tus kheej-compacting precast qhob Cheebtsam, thiab muaj kev cuam tshuam rau cov pob zeb molding, daws cov teeb meem ntawm cov khoom tsis txaus.Ntxiv rau cov hmoov limestone tau hais los saum no, dolomite thiab granite hmoov nrog cov khoom zoo sib xws rau limestone kuj tuaj yeem siv los ua cov khoom sib xyaw ntawm cov pob zeb thiab cov cement.

Ntxiv rau daim ntawv thov hauv kev tsim kho kev lag luam, qib high-qib limestone sandstone mines tuaj yeem siv los tsim cov khoom lag luam siab xws li calcium carbonate, high-calcium hmoov rau flux, limestone hmoov rau desulfurization hauv thermal fais fab nroj tsuag.Cov ntawv thov no yog sib cais los ntawm kev txhawb nqa ntawmlimestonesib tsoo zeb tshuab.Raws li cov neeg tsim khoom ntawmlimestonesib tsoo zebtshuab, HCMilling (Guilin Hongcheng) tsim limestone sib tsoo zeb tshuab khoom xws liLimestone Raymondtshuab tshuab, limestone ntsugsib tsoo tshuab, limestone ultra-zoosib tsoo zebtshuab, thiab lwm yam. Nws muab cov cuab yeej zoo txhawb rau kev tsim thiab siv cov hmoov limestone, thiab tuaj yeem ua cov 80-2500 mesh limestone hmoov.Txoj haujlwm limestone hmoov muaj kev paub dhau los hauv kev tsim thiab ntau tus neeg siv khoom.

Yog tias koj muaj qee qhov kev xav tau, thov hu rau peb kom paub cov ntaub ntawv ntawm cov khoom siv limestonesib tsoo zeb tshuab.
