Limestone idombo re sedimentary, rinonyanya kuumbwa ne calcium carbonate uye magnesium carbonate.Chinangwa chayo chikuru ndechekugadzira jecha aggregate.Matombo machipisi uye hupfu hwebwe hunogadzirwa mukugadzirisa nekugadzira hunova limestone tailings.Limestone tailings inogayiwa kuita limestone podachigayo chekuya.Inogona kushandiswa sekongiri musanganiswa uye kongiri yakafanogadzirwa zvikamu kuti uwedzere kushandiswa kwematombo machipisi.Somugadziri we limestonekugayamuchina, HCMilling(Guilin Hongcheng) achasuma kushandiswa kwelimestonekugaya muchina wekugadzira limestone hupfu.
Limestone mineral poda inoreva zvidimbu zvehupfu zvine saizi isingasviki 0.075mm (inotsanangurwa mu hydraulic kongiri ine particle size isingasviki 0.16mm) inogadzirwa panguva yekugadziriswa kwejecha rekuvaka.Nzira huru dzekushandisa ndeidzi:
(1) Limestone pasi kuita mineral powder sekongiri musanganiswa: Kushandiswa kwe limestone mineral poda muindasitiri yekongiri kwakadzidzwa kwenguva yakareba.Sechikamu chikuru chemisara, mashandisiro e limestone ore poda sekongiri musanganiswa yave nzvimbo inopisa uye maitiro ekusimudzira muindasitiri yekongiri yemumba.Limestone poda inosanganiswa inert.Semusanganiswa wekongiri, limestone poda ine zvikomborero zvakajeka uye zvinogoneka: kutanga, kuwedzerwa kwechimestone powder kunogona kukurumidza hydration ye simenti;Chechipiri ndechekuti zvimedu zve limestone ore poda zvine chimiro chekuita uye kuzadza mhedzisiro.Iyo haigone kungowedzera fluidity yemusanganiswa, kuvandudza chidimbu chegiredhi chesimentitious zvinhu system, asi zvakare kuvandudza pore chimiro chekongiri;Chechitatu, limestone poda ine inoshanda.Mumakore achangopfuura, China yakatevedzana yakabudisa mitemo yenyika uye yemunharaunda, iyo yakatsigira uye yakamisa kushandiswa kwepoda yeraimestone sechinhu.Semusanganiswa wekongiri, limestone pasi kuita mineral powder ine musika wakafara uye yakanaka yemagariro uye hupfumi mabhenefiti mukufamba kwenguva.
(2) Kugadzirira kwezvakagadzirwa zvakasanganiswa musanganiswa nekukuya limestone kuita mineral powder: Iyo itsva yakafanogadzirirwa chikamu system ine zvakanakira zvekumhanya zvekuvaka, nyore kutonga kwemhando, kuchengetedza zvinhu, kunaka kwechimiro, kusimba kwesimba, kuderedzwa pa-saiti kunyorova kushanda, uye kuchengetedza kwezvakatipoteredza.Mumunda wezvigadzirwa zvakagadzirirwa, huwandu hukuru hwe limestone mineral powder mumarara emarara inogona kushandiswa sekongiri uye simende admixtures.The Standard for Quality Control ye Precast Concrete Components (DB11/T1312-2015) inoda kuti pakusarudza mamineral admixtures akadai se limestone mineral powder ye precast kongiri, kuita kwayo kunofanirwa kuzadzisa zvinodiwa nemazinga akakodzera.Zvimwe zvidzidzo zvakaratidza kuti limestone poda inogona zvinobudirira kuvandudza fluidity uye kupesana-kupatsanurwa kwekongiri mukugadzirwa kwe-vibration-isina uye self-compacting precast kongiri zvikamu, uye zvine mhedzisiro yakajeka pakuumbwa kwekongiri, kugadzirisa matambudziko ekusakwana mbishi zvinhu.Kuwedzera kune limestone poda yataurwa pamusoro apa, dolomite uye granite poda ine zvinhu zvakafanana kune limestone inogona kushandiswawo semusanganiswa wekongiri uye simende.
Pamusoro pekushandiswa muindasitiri yekuvaka, migodhi yepamusoro yelimestone sandstone inogona kushandiswa kugadzira zvigadzirwa zvepamusoro-soro senge calcium carbonate, yakakwirira-calcium poda yekuyerera, limestone poda ye desulfurization mumagetsi ekupisa.Aya maapplication haapatsanurwe kubva kune rutsigiro rwelimestonekugaya muchina.Semugadziri welimestonekugayamuchina, HCMilling(Guilin Hongcheng) inogadzira limestone yekukuya muchina michina yakadailimestone Raymondmuchina wechigayo, limestone yakatwasukamuchina wekugaya, limestone Ultra-yakanakakugayamuchina, etc. Inopa rubatsiro rwemichina yakanaka yekugadzira uye kushandiswa kweimestone powder, uye inogona kugadzira 80-2500 mesh limestone powder.Iyo limestone poda purojekiti ine ruzivo rwakapfuma mukugadzira uye akawanda evatengi makesi.
Kana iwe uine chero zvinoenderana nezvinodiwa, ndapota taura nesu kuti tidzidze ruzivo rwemidziyo ye limestonekugaya muchina.
