Nui nā ʻano lako wili a me ka hana ʻana no ka calcium kaumaha ma Kina. Ma keʻano laulā, hiki iā lākou ke hoʻokō i ka hopena o ka hana ultra-fine ma ka hui pū ʻana me ka mea hoʻokaʻawale ultra-fine e hana i kahi ʻōnaehana hana ultra-fine. Eia nō naʻe, ʻo wai ke kaʻina hana a me nā lako i ʻoi aku ka kūpono e pono ai ke loiloi pono i nā kaʻina hana like ʻole a me nā lako e like me nā koi fineness o ka mākeke a me ka loaʻa kālā nui o ka ʻoihana. A laila, pehea e koho ai i ka laina hana hana maloʻo o ka calcium kaumaha? HCMilling (Guilin Hongcheng), ma ke ʻano he mea hana o kawili wili kalipuna kaumahanā lako, ua hoʻolauna ʻia ma lalo nei e pili ana i ka hoʻohālikelike ʻana o nā kaʻina hana maloʻo o ka calcium carbonate kaumaha:

Kalipuna kāpona kaumaha wili wili kū pololei maikaʻi loa

I kēia manawa, ʻo ke koi nui ma ka mākeke calcium kaumaha o Kina he 600 ~ 1500 meshes o nā huahana calcium kaumaha; ʻO ka nui o ka hoʻonui waiwai i hoʻohui ʻia o nā huahana calcium kaumaha he haʻahaʻa (hoʻohālikelike ʻia me ka talc, barite, kaolin, a me nā mea ʻē aʻe), a ʻo ka unahi kekahi o nā kumu nui e pili ana i nā pono. I mea e hoʻokō ai i nā koi o ka mākeke a me ka loaʻa kālā o ka ʻoihana, pono e koho ʻia ka ʻenehana hana a me nā lako o ka calcium kaumaha ma ke kumumanaʻo: ʻenehana makua, hana pono, kūlana huahana paʻa, hoʻopukapuka kālā liʻiliʻi no kēlā me kēia tona o ka huahana, a me ka hoʻohana ikehu haʻahaʻa. Pehea e koho ai i ka laina hana hana maloʻo no ka calcium kaumaha? ʻO nā lako hana maloʻo superfine no ka calcium kaumaha ua haku nui ʻia me nā lako wili a me ka grading. ʻO nā lako wili makua e pili ana i ka calcium carbonate kaumaha Raymond mill, vibration mill, calcium carbonate kaumaha ultra-fine ring roller mill, dry stirring mill,wili wili kū pololei calcium carbonate kaumahaa me ka wili pōpō. ʻO nā lako hoʻokaʻawale he mea hoʻokaʻawale superfine ʻano impeller i hana ʻia e ke kumumanaʻo o ke au eddy i hoʻoikaika ʻia. Eia ka hoʻohālikelike ʻana o ke kaʻina hana maloʻo o ka calcium carbonate kaumaha e pili ana i nā ʻano loea o nā lako wili:

(1) kaʻina hana hoʻokaʻawale calcium carbonate kaumaha ʻo Raymond mill+no ka calcium carbonate kaumaha. No ka wili Raymond ka ʻōwili a me ka kuʻi ʻana. Hoʻokele ka motika i ka wili wili, a hoʻohana ʻia ka ikaika centrifugal e koi i nā mea e ʻomi, friction a me ka ʻokiʻoki i ka wikiwiki haʻahaʻa, me ka kuʻi ʻana i ka hopena intermittent. Loaʻa i ka wili Raymond nā pono nui ma ke ʻano o ka hoʻopukapuka kālā a me ka hoʻohana ʻana i ka ikehu i ka wā e hana ai i nā huahana ma lalo o 400 meshes. Eia nō naʻe, ʻo ke kumumanaʻo o ka ʻōwili a me ka kuʻi ʻana e hoʻoholo ana he liʻiliʻi ka nui o ka pauka maikaʻi i hana ʻia e ka wili Raymond. No ka laʻana, ma waena o ka pauka maikaʻi 400 mesh, ʻo ka pauka maikaʻi <10 m wale nō ka helu no kahi 36% o g1]. Ma keʻano laulā, hiki ke hoʻololi ʻia ka wili Raymond a i ʻole hiki ke hoʻohui ʻia ka ʻōnaehana grading ultra-fine e hana i nā huahana ultra-fine o 800 ~ 1250 meshes. Eia naʻe, ma muli o ka haʻahaʻa o ka pauka micro, ʻo ka hiki ke hana o ka pauka calcium kaumaha superfine ma luna o 800 meshes me ka wili Raymond he liʻiliʻi.

(2) Kaʻina hana wili maloʻo + ka mea hoʻokaʻawale. Ua ʻike ʻia hoʻi ka wili maloʻo ʻo ia ka wili pōpō hoʻoulu. ʻO ke kino wili he cylinder kū pololei, me kahi ʻau hoʻoulu ma waena, a ua hoʻohuli ʻia nā mea holoholona a me ka medium e hana i ka wili. He kiʻekiʻe kona pono wili, a hiki ke hoʻohana pū ʻia me kahi mea hoʻokaʻawale, ʻoi aku ka kūpono no ka hana ʻana i ka calcium kaumaha superfine ma luna o 1250 mesh; Eia naʻe, ma muli o ka nui o ka pilina ma waena o nā mea a me nā mea wili, nui ka haumia o nā mea haumia a maikaʻi ʻole ka hopena palekana o ke kaiapuni.

(3) Kaʻina hana hoʻokaʻawale ʻana o ka wili haʻalulu. ʻO ka wili haʻalulu ka hoʻohana ʻana i ka haʻalulu alapine kiʻekiʻe e hana i ka hopena ikaika a me ka wili ʻana ma waena o ka mea wili a me nā mea, i mea e wāwahi ai i nā mea. Loaʻa i ka wili haʻalulu ka pono wili kiʻekiʻe a me ka nui o ka pauka maikaʻi i loko o ka pauka, ʻoi aku ka kūpono no ka wili ʻana i nā huahana me ka nui o ka mesh ma mua o 1250; He nui ka lakio o ke anawaena o ka wili haʻalulu, a he koʻikoʻi ka hanana wili nui. ʻAʻole ia he koho maikaʻi no ka hana ʻana i ka calcium kaumaha.

(4) Kaʻina hana wili apo superfine calcium carbonate+classifier. Ua like ke ʻano mechanical a me ke ʻano wili o ka wili apo me ko ka wili Raymond. No lāua ʻelua i ke kaomi centrifugal o ka wili wili e hānai i nā mea a wāwahi iā lākou. Eia naʻe, ua hoʻomaikaʻi nui ʻia ke ʻano o ka wili wili. ʻOi aku ka maikaʻi o kāna hana wili ma mua o ka wili Raymond, a hoʻohana nui ʻia lākou e hana i ka calcium kaumaha superfine ma lalo o 1500 meshes. I kēia manawa, ua hoʻolaha koke ʻia kēia ʻano mea hana wili i ka ʻoihana calcium kaumaha ma muli o kona mālama mana a me ka hoʻopukapuka haʻahaʻa. No ka laʻana, ua hōʻoia ʻia ka wili apo HCH1395 e ka China Calcium Carbonate Association ma ke ʻano he mea mālama ikehu a me ka hoʻemi ʻana i ka hoʻohana ʻana ma ke kahua o ka hana superfine calcium carbonate ma Kina.

(5) Kaʻina hana wili wili kū pololei calcium carbonate+classifier. ʻO ke ʻano wili o ka wili wili kū pololei (i kapa ʻia ʻo ka wili wili kū pololei no ka pōkole) ua like ia me ka wili Raymond, nona ka wili a me ka kuʻi ʻana. Ma muli o ke kaomi ʻana o ka wili e ke ʻano hydraulic kiʻekiʻe, piʻi ke kaomi wili o ka wili ma luna o nā mea i nā ʻumi manawa a ʻoi aku paha, no laila ʻoi aku ka maikaʻi o kāna hana kuʻi ʻana ma mua o ka wili Raymond. I kēia manawa, ʻo ia kekahi o nā lako hana nui no ka hana nui ʻana o ka calcium kaumaha. ʻO ka wili wili kū pololei super-fine HLMX series i hoʻomohala ʻia e HCMilling (Guilin Hongcheng) ma ke kumu o ka wili wili kū pololei maʻamau hiki ke hoʻokaʻawale i nā ʻāpana maikaʻi o nā mea i wili ʻia e ka wili wili kū pololei, a ʻo ka laulā fineness hoʻokaʻawale he 3um a 45um. Hiki iā ia ke hoʻokō i ka hana ʻana o nā huahana o nā kikoʻī like ʻole me hoʻokahi wili wili kū pololei, a hiki ke hana wikiwiki a paʻa i nā huahana o ka fineness like. Ua hoʻonohonoho ʻia ka ʻōnaehana hoʻokaʻawale ea lua, nona ka pono hoʻokaʻawale kiʻekiʻe, hiki ke hoʻokaʻawale pono i ka pauka coarse a me ka pauka maikaʻi, a hiki i ka fineness hoʻokaʻawale a hiki i ka 3 μ m. E kiʻi i nā huahana kūpono o nā kikoʻī like ʻole. Hoʻohana nui ʻia ia i ka hana ʻana i nā minelala ʻaʻole metala e like me ka calcite, barite, talc a me kaolin. Ma ka lawe ʻana i ka hana ʻana o ka pauka calcium carbonate ma ke ʻano he laʻana, hiki iā ia ke hana i nā huahana 325-3000 mesh, kūpono loa no nā huahana 800-2500 mesh, me kahi pālākiō hana hoʻokahi o 4-40t/h. Hoʻohana nui ʻia e nā ʻoihana kūloko ma luna o ka nui i koho ʻia a me nā ʻoihana pauka kaulana ma ʻEulopa a me ʻAmelika.

(6) Kaʻina hana wili pōpō + ka mea hoʻokaʻawale. ʻO ke kumumanaʻo kuʻi o ka wili pōpō, ʻo ia ka hopena o nā mea a me nā mea wili a wili kekahi i kekahi i ke kaʻina hana hoʻohuli o ka wili pōpō. ʻOi aku ka haʻahaʻa o kāna pauka maikaʻi ma mua o nā huahana i wili ʻia e ka wili hoʻoulu maloʻo a me ka wili haʻalulu, akā ʻoi aku ka kiʻekiʻe o kona hiki ke hana ma mua o nā lako hana ʻē aʻe, kahi kūpono no nā ʻoihana hana nui. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka ikehu o nā huahana me ka maikaʻi like a me ka hiki ma mua o ka ʻōnaehana wili wili kū pololei. ʻO kona pono, kokoke ke ʻano o ka ʻāpana o ka huahana i ka poepoe, a ʻo ka ʻoihana e koi ana i ke ʻano o ka ʻāpana he pono ia ʻaʻole hiki i nā hana ʻē aʻe ke hoʻohālikelike.

I kēia manawa, nui nā mea hana ma ka mākeke ʻenehana hana calcium kaumaha a me nā lako, a ke alakaʻi nei nā ʻōkuhi loea ma ka home a i ʻole ma ka honua holoʻokoʻa. No nā mea hoʻopukapuka kālā, he paʻakikī ke hoʻomaopopo i ke kūlana maoli. Manaʻo ʻia e nānā nā mea hoʻopukapuka kālā i nā hoʻonā loea o nā mea hana ʻenehana kaulana o ka honua e hoʻomaopopo i kā lākou mau ʻōkuhi loea i ka wā e kū nei i nā hoʻonā loea a me nā ʻōkuhi loea. Ma ke kahua o ka hana mīkini o nā huahana calcium kaumaha, ua like mau a kokoke paha nā ʻōkuhi loea holomua. Ma ke ʻano o nā lako hana calcium kaumaha, no ka laina hana like, ʻokoʻa paha ka mana i hoʻokomo ʻia o kēlā me kēia mea hana lako ma 30% a ʻoi aku paha. Ma ke koho ʻana i nā ʻōnaehana loea kūpono a ʻepekema hiki ke hoʻokō ʻia nā hopena hana kūpono a me nā pono waiwai.

Ma ke ʻano he mea hana me kahi kokoke i 30 mau makahiki o ka ʻike i ka hana ʻana i nā lako hana pauka calcium, loaʻa iā HCMilling (Guilin Hongcheng) nā hihia mea kūʻai aku waiwai. ʻO kā mākou lako hana hana maloʻo calcium carbonate kaumaha, e like mekalaka kalapona kaumaha Wili Raymond, calcium carbonate kaumaha wili wili apo maikaʻi loaa mekalaka kalapona kaumaha wili wili kū pololei maikaʻi loa, hauʻoli i kahi inoa maikaʻi ma ka home a ma waho. Inā he mau nīnau kāu e pili ana i ke koho ʻana i ka laina hana hana maloʻo no ka calcium kaumaha, e ʻoluʻolu e kelepona mai iā mākou no nā kikoʻī.
