Limestone ndi thanthwe la sedimentary, makamaka lopangidwa ndi calcium carbonate ndi magnesium carbonate.Cholinga chake chachikulu ndikukonza mchenga.Tchipisi tamiyala ndi ufa wamwala wopangidwa pokonza ndi kupanga zimakhala zomangira miyala yamwala.Miyendo ya miyala ya laimu imaphwanyidwa kukhala ufa wa laimumphero ya miyala yamchere.Itha kugwiritsidwa ntchito ngati kusakaniza konkriti ndi zida zopangira konkriti kuti muwonjezere kugwiritsa ntchito tchipisi ta miyala.Monga wopanga miyala yamcherempheromakina, HCMilling(Guilin Hongcheng) adzayambitsa ntchitomiyala yamcheremphero makina opangira ufa wa laimu.

Laimu mchere ufa amatanthauza particles ufa ndi tinthu kukula zosakwana 0.075mm (chotanthauziridwa mu hayidiroliki konkire ndi tinthu kukula zosakwana 0.16mm) opangidwa pokonza yomanga mchenga akaphatikiza.Njira zazikulu zogwiritsira ntchito ndi:

(1) Limestone pansi kukhala mchere wa ufa monga wosakaniza konkire: Kugwiritsa ntchito ufa wa mchere wa laimu m'makampani a konkire kwaphunziridwa kwa nthawi yaitali.Monga gawo lalikulu la michira, momwe mungagwiritsire ntchito ufa wa miyala yamwala ngati konkire kusakaniza kwakhala kotentha kwambiri komanso chitukuko m'makampani a konkire.Limestone ufa ndi kuphatikiza kwa inert.Monga kusakaniza kwa konkire, ufa wa laimu uli ndi ubwino woonekeratu ndi zotheka: choyamba, kuwonjezera pa ufa wa laimu kumatha kufulumizitsa hydration ya simenti;Chachiwiri ndi chakuti tinthu tating'onoting'ono ta ufa wa laimu timakhala ndi mawonekedwe komanso kudzaza.Iwo akhoza kuwonjezera fluidity wa osakaniza, kusintha tinthu kusanja dongosolo cementitious chuma, komanso kusintha pore dongosolo konkire;Chachitatu, ufa wa laimu uli ndi mphamvu yogwira ntchito.M'zaka zaposachedwa, dziko la China latulutsa motsatizana malamulo adziko lonse komanso am'deralo, omwe atsimikizira ndikugwiritsa ntchito ufa wa laimu ngati gwero.Monga kusakaniza konkire, miyala ya miyala yamchere kukhala ufa wa mchere imakhala ndi msika wotakata komanso phindu labwino pazachuma komanso pazachuma pamapeto pake.

(2) Kukonzekera kwa prefabricated chigawo admixture pogaya miyala ya laimu mu mchere ufa: latsopano prefabricated chigawo dongosolo ali ndi ubwino wa liwiro kumanga mofulumira, mosavuta kulamulira khalidwe, kupulumutsa chuma, maonekedwe abwino, durability, kuchepetsa pa malo ntchito yonyowa, ndi kuteteza chilengedwe.M'munda wa zigawo zokonzedweratu, kuchuluka kwa miyala yamchere yamchere yamchere m'mizere ya miyala yamwala ingagwiritsidwenso ntchito ngati konkriti ndi simenti admixtures.The Standard for Quality Control of Precast Concrete Components (DB11/T1312-2015) imafuna kuti posankha zosakaniza za mchere monga ufa wa mchere wa laimu wa precast konkire, ntchito yake iyenera kukwaniritsa zofunikira za miyezo yoyenera.Kafukufuku wina wasonyeza kuti ufa wa miyala ya laimu ukhoza bwino kusintha fluidity ndi odana ndi kulekana kwa konkire kupanga kugwedera-free ndi kudziona compacting precast konkire zigawo zikuluzikulu, ndipo ali ndi zotsatira zoonekeratu pa akamaumba konkire, kuthetsa mavuto osakwanira zipangizo zopangira.Kuphatikiza pa ufa wa laimu wotchulidwa pamwambapa, ufa wa dolomite ndi granite wokhala ndi zinthu zofanana ndi miyala yamchere angagwiritsidwe ntchito ngati kusakaniza konkire ndi simenti.

Kuphatikiza pa ntchito yomangamanga, migodi ya mchenga wa miyala yamtengo wapatali yamtengo wapatali ingagwiritsidwe ntchito kupanga zinthu zapamwamba monga calcium carbonate, high-calcium powder for flux, laimu ufa wa desulfurization mu zomera zotentha.Mapulogalamuwa ndi osasiyanitsidwa ndi chithandizo chamiyala yamcheremphero makina.Monga wopangamiyala yamcherempheromakina, HCMilling(Guilin Hongcheng) umabala laimu akupera zida makina mphero mongaRaymond mwalamakina a mphero, miyala yamchere yoyimamakina opangira mphero, miyala yamchere kwambirimpheromakina, etc. Amapereka zida zabwino zothandizira kupanga ndi kugwiritsa ntchito ufa wa laimu, ndipo amatha kukonza ufa wa 80-2500 mesh laimu.Pulojekiti ya ufa wa limestone ili ndi chidziwitso chochuluka pakupanga komanso makasitomala ambiri.

Ngati muli ndi zofunikira zilizonse, chonde titumizireni kuti mudziwe zambiri za zida miyala yamcheremphero makina.
