Pob zeb limestone yog pob zeb sedimentary, feem ntau yog ua los ntawm calcium carbonate thiab magnesium carbonate. Nws lub hom phiaj tseem ceeb yog los ua cov xuab zeb sib xyaw. Cov pob zeb me me thiab hmoov pob zeb uas tsim tawm thaum lub sijhawm ua thiab tsim khoom dhau los ua cov limestone tailings. Cov limestone tailings raug zom ua hmoov limestone los ntawmzeb zeb sib tsooNws tuaj yeem siv ua cov khoom sib xyaw ua ke thiab cov khoom siv ua ntej ua ntej kom siv tau cov pob zeb ua tej daim ntau ntau. Ua tus tsim khoom ntawm pob zeb av nplaumlub tshuab sib tsootshuab, HCMilling (Guilin Hongcheng) yuav qhia txog daim ntawv thov ntawmpob zeb av nplaumlub tshuab sib tsoo tshuab ua cov hmoov limestone.

Hmoov pob zeb limestone yog hais txog cov hmoov me me uas muaj qhov loj me tsawg dua 0.075 hli (txhais hauv cov pob zeb hydraulic nrog qhov loj me tsawg dua 0.16 hli) tsim tawm thaum lub sijhawm ua cov xuab zeb sib xyaw ua ke. Cov txheej txheem siv tseem ceeb yog:

(1) Pob zeb limestone zom ua hmoov av ua cov khoom sib xyaw ua ke: Kev siv cov hmoov av limestone hauv kev lag luam pob zeb tau kawm ntev heev. Raws li cov khoom tseem ceeb ntawm cov tailings, yuav ua li cas siv cov hmoov av limestone ua cov khoom sib xyaw ua ke tau dhau los ua qhov chaw kub thiab kev txhim kho hauv kev lag luam pob zeb hauv tsev. Hmoov av limestone yog cov khoom sib xyaw ua ke. Raws li cov khoom sib xyaw rau pob zeb, hmoov av limestone muaj qhov zoo thiab qhov ua tau: thawj zaug, kev ntxiv cov hmoov av limestone tuaj yeem ua kom cov cement noo sai dua; Qhov thib ob yog tias cov khoom me me ntawm cov hmoov av limestone muaj cov duab zoo thiab cov nyhuv sau. Nws tsis tsuas yog ua rau kom cov kua ntawm cov khoom sib xyaw ua ke ntau ntxiv, txhim kho cov khoom me me ntawm cov khoom siv cementitious, tab sis kuj txhim kho cov qauv ntawm cov pob zeb; Qhov thib peb, hmoov av limestone muaj cov nyhuv nquag. Nyob rau hauv xyoo tas los no, Tuam Tshoj tau tshaj tawm cov qauv hauv tebchaws thiab hauv zos, uas tau lees paub thiab ua tus qauv rau kev siv cov hmoov av limestone ua cov peev txheej. Raws li cov khoom sib xyaw ua ke, pob zeb limestone zom ua hmoov av muaj kev lag luam dav thiab cov txiaj ntsig zoo rau kev sib raug zoo thiab kev lag luam hauv lub sijhawm ntev.

(2) Kev npaj cov khoom sib xyaw ua ntej los ntawm kev sib tsoo limestone rau hauv cov hmoov av: Lub kaw lus tshiab prefabricated muaj qhov zoo ntawm kev tsim kho sai, kev tswj hwm zoo yooj yim, kev txuag khoom siv, qhov zoo li zoo, kev ruaj khov zoo, txo qhov chaw ua haujlwm ntub dej, thiab kev tiv thaiv ib puag ncig. Hauv thaj chaw ntawm cov khoom prefabricated, ntau cov hmoov av limestone hauv cov tailings limestone kuj tseem siv tau ua cov pob zeb thiab cov cement admixtures. Tus Txheej Txheem rau Kev Tswj Xyuas Zoo ntawm Cov Cheebtsam Precast Concrete (DB11 / T1312-2015) yuav tsum tau hais tias thaum xaiv cov khoom sib xyaw ua ke xws li cov hmoov av limestone rau cov pob zeb precast, nws cov kev ua tau zoo yuav tsum ua tau raws li cov qauv cuam tshuam. Qee qhov kev tshawb fawb tau qhia tias cov hmoov limestone tuaj yeem txhim kho qhov fluidity thiab tiv thaiv kev sib cais ntawm cov pob zeb hauv kev tsim cov khoom siv precast uas tsis muaj kev co thiab tus kheej compacting, thiab muaj qhov cuam tshuam pom tseeb rau cov pwm pob zeb, daws cov teeb meem ntawm cov khoom siv raw tsis txaus. Ntxiv nrog rau cov hmoov limestone uas tau hais los saum toj no, dolomite thiab granite hmoov nrog cov khoom zoo sib xws rau limestone kuj tseem siv tau ua cov pob zeb thiab cement admixtures.

Ntxiv rau daim ntawv thov hauv kev lag luam kev tsim kho, cov pob zeb xuab zeb limestone qib siab tuaj yeem siv los tsim cov khoom lag luam zoo xws li calcium carbonate, hmoov calcium siab rau flux, hmoov limestone rau desulfurization hauv cov chaw tsim hluav taws xob thermal. Cov ntawv thov no tsis tuaj yeem sib cais los ntawm kev txhawb nqa ntawmpob zeb av nplaumlub tshuab sib tsoo tshuab. Raws li tus neeg tsim khoom ntawmpob zeb av nplaumlub tshuab sib tsootshuab, HCMilling (Guilin Hongcheng) tsim cov khoom siv sib tsoo limestone xws lipob zeb Raymondtshuab zeb, pob zeb limestone ntsugtshuab sib tsoo, limestone zoo heevlub tshuab sib tsootshuab, thiab lwm yam. Nws muab kev txhawb nqa cov khoom siv zoo rau kev tsim thiab siv cov hmoov limestone, thiab tuaj yeem ua cov hmoov limestone 80-2500 mesh. Qhov project hmoov limestone muaj kev paub nplua nuj hauv kev tsim qauv thiab ntau tus neeg siv khoom.

Yog tias koj muaj cov kev xav tau tshwj xeeb, thov hu rau peb kom paub cov ntsiab lus ntawm cov khoom siv pob zeb av nplaumlub tshuab sib tsoo tshuab.
