He pōhaku sedimentary ka Limestone, i haku ʻia me ka calcium carbonate a me ka magnesium carbonate. ʻO kāna kumu nui ka hana ʻana i ka one aggregate. ʻO nā ʻāpana pōhaku a me ka pauka pōhaku i hana ʻia i ke kaʻina hana a me ka hana ʻana e lilo i nā ʻōpala limestone. Kuʻi ʻia nā ʻōpala limestone i pauka limestone ewili wili pōhaku lepoHiki ke hoʻohana ʻia e like me ka hui ʻana o ka sima a me nā ʻāpana i hana mua ʻia no ka sima e hoʻonui i ka hoʻohana ʻana i nā ʻāpana pōhaku. Ma ke ʻano he mea hana o pōhaku lepowili wilimīkini, e hoʻolauna ʻo HCMilling (Guilin Hongcheng) i ka noi opōhaku lepowili wili mīkini e hana i ka pauka pōhaku lepo.

ʻO ka pauka mineral limestone e pili ana i nā ʻāpana pauka me ka nui o nā ʻāpana ma lalo o 0.075mm (i wehewehe ʻia i loko o ka sima hydraulic me ka nui o nā ʻāpana ma lalo o 0.16mm) i hana ʻia i ka wā o ka hana ʻana o ka hoʻohuihui one kūkulu. ʻO nā ʻano noi nui:

(1) ʻO ka lepo limestone i wili ʻia i loko o ka pauka mineral e like me ka hui ʻana o ka sima: Ua lōʻihi ka noi ʻana o ka pauka mineral limestone i loko o ka ʻoihana sima. Ma ke ʻano he ʻāpana nui o nā tailings, pehea e hoʻohana ai i ka pauka ore limestone e like me ka hui ʻana o ka sima ua lilo ia i wahi wela a me ke ʻano hoʻomohala i ka ʻoihana sima kūloko. ʻO ka pauka limestone kahi hui inert. Ma ke ʻano he hui no ka sima, he mau pono maopopo a me ka hiki ke hana ʻia ka pauka limestone: ʻo ka mea mua, hiki i ka hoʻohui ʻana o ka pauka limestone ke hoʻolalelale i ka hydration o ka sima; ʻO ka lua, ʻo nā ʻāpana o ka pauka ore limestone he hopena ʻano a me ka hopena hoʻopiha. ʻAʻole hiki ke hoʻonui wale i ka wai o ka hui ʻana, hoʻomaikaʻi i ka grading ʻāpana o ka ʻōnaehana mea sima, akā hoʻomaikaʻi pū i ka hoʻonohonoho pore o ka sima; ʻO ke kolu, he hopena ikaika ka pauka limestone. I nā makahiki i hala iho nei, ua hoʻopuka mau ʻo Kina i nā kūlana aupuni a me nā kūloko, i hōʻoia a hoʻopaʻa i ka hoʻohana ʻana i ka pauka limestone ma ke ʻano he kumuwaiwai. Ma ke ʻano he hui ʻana o ka sima, he mākeke ākea ka limestone i wili ʻia i loko o ka pauka mineral a me nā pono pilikanaka a me ka hoʻokele waiwai maikaʻi i ka wā lōʻihi.

(2) Hoʻomākaukau ʻana i ka hui ʻāpana i hana mua ʻia ma ke wili ʻana i ka pōhaku lepo i loko o ka pauka mineral: Loaʻa i ka ʻōnaehana ʻāpana i hana mua ʻia nā pono o ka wikiwiki o ke kūkulu ʻana, ka maʻalahi o ka kaohi ʻana i ka maikaʻi, ka mālama ʻana i nā mea, ke ʻano maikaʻi, ka lōʻihi maikaʻi, ka hoʻemi ʻana i ka hana pulu ma kahi, a me ka palekana o ke kaiapuni. Ma ke kahua o nā ʻāpana i hana mua ʻia, hiki ke hoʻohana ʻia ka nui o ka pauka mineral limestone i loko o nā ʻōpala limestone e like me nā hui sima a me ka sima. Ke koi nei ke Kūlana no ka Manaʻo Kūlana o nā ʻĀpana Sima Precast (DB11/T1312-2015) i ka wā e koho ai i nā hui mineral e like me ka pauka mineral limestone no ka sima precast, pono e hoʻokō kāna hana i nā koi o nā kūlana pili. Ua hōʻike kekahi mau haʻawina e hiki i ka pauka limestone ke hoʻomaikaʻi maikaʻi i ka wai a me ka anti-separation o ka sima i ka hana ʻana i nā ʻāpana sima precast ʻole haʻalulu a me ka hoʻopaʻa ponoʻī, a he hopena maopopo i ka hoʻoheheʻe ʻana i ka sima, e hoʻoponopono ana i nā pilikia o nā mea maka ʻole. Ma waho aʻe o ka pauka limestone i ʻōlelo ʻia ma luna, hiki ke hoʻohana ʻia ka pauka dolomite a me ka granite me nā waiwai like me ka limestone e like me ka hui ʻana o ka sima a me ka sima.

Ma waho aʻe o ka hoʻohana ʻana i ka ʻoihana kūkulu hale, hiki ke hoʻohana ʻia nā mines one limestone kiʻekiʻe e hoʻomohala i nā huahana kiʻekiʻe e like me ka calcium carbonate, ka pauka calcium kiʻekiʻe no ka flux, ka pauka limestone no ka desulfurization i nā mea kanu mana wela. ʻAʻole hiki ke hoʻokaʻawale ʻia kēia mau noi mai ke kākoʻo opōhaku lepowili wili mīkini. Ma ke ʻano he mea hana opōhaku lepowili wilimīkini, hana ʻo HCMilling (Guilin Hongcheng) i nā lako mīkini wili limestone e like mepōhaku lepo ʻo Raymondmīkini wili, pōhaku lepo kū pololeimīkini wili, pōhaku lepo maikaʻi loawili wilimīkini, a pēlā aku. Hāʻawi ia i ke kākoʻo lako maikaʻi no ka hana ʻana a me ka hoʻopili ʻana i ka pauka limestone, a hiki ke hana i ka pauka limestone 80-2500 mesh. Loaʻa i ka papahana pauka limestone ka ʻike nui i ka hoʻolālā a me nā hihia he nui o nā mea kūʻai aku.

Inā he mau koi pili kāu, e ʻoluʻolu e leka uila mai iā mākou e aʻo i nā kikoʻī o nā lako o pōhaku lepowili wili mīkini.
