ʻO ka calcium carbonate he mea hoʻohuihui ʻole ʻo ia ka mea nui o ka pōhaku limestone (ka limestone no ka pōkole) a me ka calcite.Hoʻokaʻawale ʻia ka calcium carbonate i ʻelua mau ʻāpana: calcium carbonate kaumaha a me ka calcium carbonate māmā.Ma ke ʻano he mea hana lako calcium carbonate, HC, HCQ series Raymond mill, HLM series vertical mill, HLMX series ultra-fine vertical mill, HCH series ring roller mill i hana ʻia e HCM Machinery ua hoʻohana nui ʻia i ka hana a me ka hana ʻana o ka calcium carbonate.I kēia lā,Mīkini HCMe hoʻolauna iā ʻoe i ka ʻenehana hana a me nā mea hana o ka calcium carbonate.ʻO ka mea mua, ka hana ʻana o ka calcium carbonate kaumaha a me ka ʻenehana hana I kēia manawa, ʻelua mau kaʻina hana nui no ka hana ʻana o ka calcium carbonate kaumaha, hoʻokahi ka hana maloʻo;ʻO kekahi kahi ʻano pulu, hana maloʻo o nā huahana, hiki ke hoʻohana nui ʻia i ka lāʻau, plastics, coatings a me nā ʻoihana ʻē aʻe.Hoʻohana ʻia ke kaʻina wai ma ka ʻoihana pepa, a kūʻai ʻia ka huahana maʻamau ma ke ʻano pulp i nā wili pepa.1. Kaʻina hana maloʻo: Raw Materials → Gangue removal → Jaw Crusher → Impact hammer Crusher → Raymond Mill/ultrafine vertical mill → Grading system → Packaging → Product.ʻO ka mua, hoʻoneʻe ʻia ka gangue e ka lima ma ke koho ʻana i ka calcite, limestone, chalk, seashells, etc., i lawe ʻia mai ka quarry.A laila ʻoki ʻia ka limestone e ka mea ʻuʻuku, a laila ʻoki ʻia ka pauka calcite maikaʻi e Raymond (pendulum) wili ʻia, a ʻo ka hope loa e helu ʻia ka pauka wili ʻia e ka classifier, a ʻo ka pauka e kū ana i nā koi nui o ka nui e hoʻopili ʻia i loko o ka waihona. ma ke ʻano he huahana, i ʻole e hoʻihoʻi ʻia i ka mīkini wili e wili hou.
2, kaʻina hana pulu:
ʻOka maka → ʻāwae haʻihaʻi → ʻili ʻo Raymond → wili hui pulu a i ʻole mīkini wehe ʻia (i ka manawa pōkole, multi-stage a i ʻole ka pōʻai)→ Wet classifier 1 → kānana → hoʻomaloʻo → hoʻōla → Packaging → Huahana.
ʻO ka mea mua, ʻo ka hoʻokuʻu ʻia ʻana o ka pauka maloʻo maloʻo e ʻoki hou ʻia i ka wili, a ma hope o ka maloʻo ʻana a me ka maloʻo ʻana, hoʻomākaukau ʻia ka calcium carbonate kaumaha nui.ʻO nā kaʻina hana nui o ka wili ʻana i ka calcium carbonate kaumaha:
(1) Raw ore → haʻi ʻauwae → Raymond mill → wili hoʻoulu ʻana a i ʻole mīkini ʻili (intermittent, multi-stage or cycle)→ wet classifier → screening → drying → activation → bagging (coating grade heavy calcium).Hoʻohui ʻia ka hoʻokaʻawale ʻana o ka superfine i ke kaʻina hana, hiki ke hoʻokaʻawale i nā huahana kūpono i ka manawa a hoʻomaikaʻi i ka pono.ʻO nā lako hoʻokaʻawale ʻana i ka wai ʻoi aku ka liʻiliʻi o ke anawaena liʻiliʻi, ka mea hoʻokaʻawale spiral a me ka papa helu kīʻaha, ʻoi aku ka lahilahi o ka neʻe ʻana o ka pulp ma hope o ka hoʻohālikelike ʻana, i kekahi manawa pono e hoʻohui i ka pahu sedimentation.Maikaʻi ka papa kuhikuhi waiwai o ke kaʻina hana, akā paʻakikī ka hoʻokaʻawale ʻana, ʻaʻohe mea hoʻomaʻamaʻa maikaʻi loa.
(2) Raw ore → auwae haki - Raymond mill → pulu wili wili - kānana → hoʻomaloʻo -→ ho'ā - → ʻeke ʻeke (packing grade heavy calcium).
(3) ʻOka maka → ʻāʻī āwae → Milla Raymond → ka mīkini hoʻoulu ʻana a i ʻole ka mīkini ʻili (kekahi, ka nui a i ʻole ka pōʻai) → ka nānā ʻana (ka uhi ʻana o ka pepa i ka slurry calcium kaumaha).
ʻO ka lua, ʻo ka hana ʻana o ka calcium carbonate māmā a me ka ʻenehana hana hoʻomākaukau ʻana o ka calcium carbonate māmā: ua haki ka limestone maka i kekahi nui, ka lime kiln forging a puhi i ka lime (Ca0) a me ka flue gas (kiln gas i loaʻa ka carbon dioxide), ka lime. hoʻokomo ʻia i loko o kahi digester mau a hoʻohui ʻia ka wai no ka hoʻoheheʻe ʻana e loaʻa ai ka emulsion Ca (OH)2.Ma hope o ka kānana ʻana a me ka hoʻomaʻemaʻe ʻana, hoʻouna ʻia ka emulsion maikaʻi Ca (OH) 2 i ka carbonization reactor/carbonization hale kiaʻi a i loko o ke kinoea kiln i hoʻomaʻemaʻe ʻia i loaʻa ka carbon dioxide no ka hoʻohui ʻana i ka carbonization.I ka manawa like, ua hoʻohui ʻia ka nui kūpono o nā mea hoʻohui e hana ma lalo o kekahi mau kūlana ʻenehana e hana i ka calcium carbonate ultra-fine.Ua hoʻokomo ʻia ka slurry calcium carbonate superfine i loko o ka reactor uhi a ua hoʻohui ʻia ka mea hoʻopili helu quantitative e hana ma lalo o kekahi mau kūlana ʻenehana no ka loaʻa ʻana o nā huahana calcium carbonate ikaika me ka hoʻololi ʻana i ka ʻili.ʻO ka ultra-fine active calcium carbonate slurry ua kānana a maloʻo, a laila hoʻouna ʻia i ka mea maloʻo no ka hoʻomaʻemaʻe hou ʻana a hiki i ka pauka maloʻo i koi ʻia no ka ʻike wai, a laila ʻoki ʻia no ka hoʻopili ʻana o ka huahana.
ʻO ka mea i luna nei ka hoʻoili ʻana o ka calcium carbonate a me ka hoʻolauna ʻenehana hana.Inā makemake ʻoe e ʻike hou aʻe e pili ana i ka hana ʻana o ka calcium carbonate a me ka ʻenehana hana, e ʻoluʻolu e hāʻawi mai iā mākou i kahi leka no nā kikoʻī:hcmkt@hcmilling.com
