Dhagaxa limestone waa dhagax sedimentary ah, oo inta badan ka kooban calcium carbonate iyo magnesium carbonate.Ujeeddadeeda ugu weyn waa in la habeeyo wadarta ciidda.Dhagaxyada dhagxaanta iyo budada dhagaxa ee la soo saaro habka wax-soo-saarka iyo wax-soo-saarka ayaa noqda dabo-dhagax-dhagax.Dabada limestone waxaa lagu shubaa budada nuuradeedka bydhagax nuurad shiidi.Waxaa loo isticmaali karaa sida isku-darka shubka ah iyo qaybo la sii diyaariyay oo shub ah si loo kordhiyo isticmaalka jajabyada dhagxaanta.Sida soo saaraha ee dhagax nuuradshiididmashiinka, HCMilling (Guilin Hongcheng) ayaa soo bandhigi doona codsigadhagax nuuradshiidid mashiinka lagu farsameeyo budada nuuradda.

Budada macdanta limestone waxaa loola jeedaa qaybaha budada ah ee cabbirkoodu ka yar yahay 0.075mm (oo lagu qeexay shubka hydraulic oo leh cabbirka qayb ka yar 0.16mm) oo la soo saaro inta lagu jiro habaynta isku-darka ciidda dhismaha.Siyaabaha codsiga ugu muhiimsan waa:

(1) Dhagax nuurad ah oo lagu shubo budada macdanta sida isku-darka la taaban karo: Codsiga budada macdanta macdanta ee warshadaha shubka ah ayaa la bartay muddo dheer.Sida qaybta ugu muhiimsan ee dabada, sida loo isticmaalo budada macdanta limestone sida isku-darka la taaban karo ayaa noqday meel kulul iyo isbeddel horumarineed ee warshadaha shubka gudaha.Budada limestone waa isku-dar aan firfircoonayn.Sida isku-dhafka ah ee la taaban karo, budada limestone waxay leedahay faa'iidooyin muuqda iyo suurtogalnimo: marka hore, ku darida budada nuuradda waxay dardargelin kartaa fuuq-celinta sibidhka;Midda labaad waa in qaybaha budada dhagaxa limestone ay leeyihiin saamayn qaabaysan iyo saamayn buuxin.Ma kordhin karto oo kaliya dareeraha isku dhafka ah, hagaajinta qayb ka mid ah nidaamka walxaha sibidhka, laakiin sidoo kale waxay hagaajinaysaa qaabdhismeedka daloolka ee la taaban karo;Saddexaad, budada limestone waxay leedahay saameyn firfircoon.Sanadihii la soo dhaafay, Shiinuhu wuxuu si isdaba joog ah u soo saaray heerar heer qaran iyo heer maxalli ah, kuwaas oo xaqiijiyay oo habeeyey isticmaalka budada limestone sida kheyraad.Sida isku-dhafka la taaban karo, dhagaxa nuuradda ah ee lagu shubay budada macdanta ayaa leh suuq ballaadhan iyo faa'iidooyin bulsho iyo dhaqaale oo wanaagsan mustaqbalka fog.

(2) Diyaarinta isku-darka qaybaha hore loo diyaariyey iyadoo lagu shiidayo dhagax nuurad ah budada macdanta: Nidaamka cusub ee qaybta hore loo diyaariyey wuxuu leeyahay faa'iidooyinka xawaaraha dhismaha degdega ah, xakamaynta tayada fudud, badbaadinta alaabta, tayada muuqaalka wanaagsan, adkeysiga wanaagsan, hoos u dhaca hawlgalka qoyan ee goobta, iyo Ilaalinta deegaanka.Goobta qaybaha hore loo diyaariyey, qadar badan oo budada macdanta ah ee dhagaxa limestone ee dabada dhagaxa limestone ayaa sidoo kale loo isticmaali karaa isku-dhafka sibidhka iyo sibidhka.Halbeegga Xakamaynta Tayada ee Qaybaha Shubka ah ee Precast (DB11/T1312-2015) waxay u baahan tahay marka la dooranayo isku-darka macdanta sida budada macdanta limestone ee shubka precast, waxqabadkeedu waa inuu buuxiyo shuruudaha heerarka khuseeya.Daraasadaha qaarkood waxay muujiyeen in budada limestone ay si wax ku ool ah u wanaajin karto dareeraha iyo ka-hortagga kala-soocidda ee la taaban karo ee soo saarista qaybaha la taaban karo ee gariir-la'aanta iyo is-xakamaynta, waxayna leedahay saameyn cad oo ku saabsan qaabeynta la taaban karo, xalinta dhibaatooyinka alaabta ceeriin ee aan ku filnayn.Marka lagu daro budada nuuradda ee kor ku xusan, dolomite iyo budada granite ee leh sifooyin la mid ah dhagax nuurad ayaa sidoo kale loo isticmaali karaa isku-darka shubka iyo sibidhka.

Marka lagu daro codsiga warshadaha dhismaha, miinooyinka dhagaxa limestone ee heerka sare ah ayaa loo isticmaali karaa si loo horumariyo alaabada sare sida calcium carbonate, budada sare ee calcium ee qulqulka, budada nuuradda ee desulfurization ee dhirta tamarta kuleylka.Codsiyadani waa kuwo aan kala sooc lahayn taageeradadhagax nuuradshiidid mashiinka.Sida soo saaraha eedhagax nuuradshiididmishiinka, HCMilling (Guilin Hongcheng) waxay soo saartaa qalabka wax lagu shiida ee dhagaxa nuuradda sidadhagax nuurad Raymondmashiinka wax lagu shubo, dhagax nuurad toosanmishiinka shiida, dhagax nuurad ultra-fineshiididmashiinka, iwm. Waxay bixisaa taageero qalab wanaagsan oo loogu talagalay soo saarista iyo codsiga budada nuuradda, waxayna ka shaqeyn kartaa 80-2500 mesh budada dhagaxa.Mashruuca budada nuuradda wuxuu leeyahay waayo-aragnimo qani ah oo ku saabsan naqshadeynta iyo kiisas badan oo macaamiisha ah.
