ʻO ka calcium carbonate kaumaha kahi mea pauka calcium carbonate i hana ʻia ma ke ʻano hana kuʻi mechanical me ka hoʻohana ʻana i ka calcite, chalk, marble a me nā ores ʻē aʻe ma ke ʻano he mea maka. Loaʻa iā ia nā ʻano o ke kumu kūʻai ākea o nā mea maka, keʻokeʻo kiʻekiʻe, ka waiwai omo aila haʻahaʻa, ka hoʻohana maikaʻi a me ke kumukūʻai haʻahaʻa. ʻO ia ka huahana pauka mineral inorganic non-metallic i hoʻohana nui ʻia me ka hoʻohana nui loa.

I kēia manawa, ʻo ka ʻenehana hana maikaʻi o ka calcium carbonate kaumaha e kālele nui ana i ka wili ʻana a me ka hoʻololi ʻana o ka ʻili e hana i nā huahana e hoʻokō i nā koi fineness o nā ʻano noi like ʻole, me ka pauka maikaʻi, ka pauka ultrafine, ka pauka i hoʻololi ʻia (hana) a me ka slurry hana pepa e komo pū ana me kekahi mau ʻano a ʻoi aku ma mua o ʻumi mau ʻano o nā huahana calcium carbonate kaumaha kūikawā me nā fineness like ʻole a me ka hoʻololi ʻana a me ka hoʻāla ʻana o ka ʻili. No laila he aha nā lako e hana ai i ka pauka calcium carbonate?Mīkini HCM he mea hana kaulana ʻo ia no nā mīkini hana pauka calcium a me nā lako hana i ka ʻoihana. I kēia lā e hoʻolauna mākou iā ʻoe i nā mīkini hana pauka calcium a me nā lako hana me nā kikoʻī.

Ka wehewehe kikoʻī ʻana i nā mīkini hana pauka calcium a me nā lako:

ʻO ka calcium carbonate kaumaha maʻamau me d97≥5μm ka mea nui i hana ʻia ma ke ʻano maloʻo. ʻO ka lako e komo pū me ka wili Raymond i hoʻomaikaʻi ʻia (wili wili kau a i ʻole ka wili pendulum), ka wili wili (me ka wili wili kaomi/wili kū, ka wili wili apo, a pēlā aku) a me ka wili pōpō, a pēlā aku.

ʻO ka calcium carbonate kaumaha Ultrafine me d97≥5μm ma ke ʻano laulā e hoʻohana i ke kaʻina hana maloʻo, a hoʻohana kekahi i ke kaʻina hana wili pulu + maloʻo. Hoʻohana nui ka hana maloʻo i nā wili pōpō pahu + nā mea hoʻokaʻawale, nā wili wili (me nā wili wili apo me ka hoʻokaʻawale ʻana i loko o ka band, nā wili kū pololei / nā wili wili kaomi), nā wili hui maloʻo + nā mea hoʻokaʻawale, a pēlā aku.

ʻO ka slurry calcium carbonate kaumaha ultra-fine me ka hana pepa me d97≤5μm, ʻoi aku hoʻi ʻo d90≤2μm, i hana pinepine ʻia e ke ʻano pulu, a ʻo nā mea hana nui he wili hoʻoulu a me kahi wili one.

Hoʻohana nui ʻia ka laina hana wili pōpō + classifier e hana i ka pauka calcium carbonate kaumaha a me ka pauka ultrafine me d97=5 ~ 43μm. Hōʻike ʻia ia e ka hana kaapuni pani mau, ka hoʻokaʻawale ʻana i nā pae he nui, ka ukana pōʻaiapuni nui (300% ~ 500%), a me ka nui o ka hana mīkini hoʻokahi. Ua hoʻohana ʻia kēia laina hana mai ka waena a hiki i ka hopena o nā makahiki 1990 a ʻo ia kekahi o nā ʻenehana hana nui no nā laina hana calcium carbonate kaumaha ultra-fine nui ma ka honua i kēia lā.

ʻO ka wili wili apo ka mea wili maikaʻi loa a me nā mea wili maikaʻi loa i hoʻohana nui ʻia ma ke kahua o ka calcium carbonate kaumaha ma Kina i nā makahiki he ʻumi i hala. Hōʻike ʻia ia e ka lakio wili nui a me ka hoʻohana ʻana i ka ikehu haʻahaʻa no kēlā me kēia huahana. Hiki i ka mea hoʻokaʻawale maikaʻi kūloko a i waho paha ke hana i nā huahana maikaʻi loa me d97≤10μm. Hiki ke hoʻoponopono ʻia ka maikaʻi o ka huahana ma waena o d97=5~40μm; ʻo ka laulā nui o ka ʻāpana huahana kūpono loa ʻo d97=10~30μm.

ʻO ka wili wili (wili wili kū pololei/wili wili) kekahi o nā lako nui nui no ka wili maikaʻi a me ka wili maikaʻi loa o ka calcium carbonate kaumaha. Hōʻike ʻia e ka lakio wili nui. ʻO ka laulā nui o ka ʻāpana huahana kūpono loa ʻo d97=15~45μm. Ma hope o ke kau ʻana o kahi mea hoʻokaʻawale maikaʻi waho, hiki iā ia ke hana i nā huahana maikaʻi loa me d97≤10μm. He ʻano ʻāpana maikaʻi ka huahana a he haʻahaʻa ka waiwai omo aila, kūpono loa no ka hana ʻana. Hoʻohana nā mea hui polyester unsaturated (pōhaku hana) i nā mea hoʻopihapiha calcium carbonate kaumaha, a he haʻahaʻa ka hoʻohana ʻana i ka ikehu a me ke komo ʻana i kēlā me kēia huahana.

Hoʻohana nui ʻia ka ʻenehana wili ultrafine pulu e hana i nā huahana papa uhi pepa (slurry) me d90≤2μm a me d97≤2μm, a me ka calcium carbonate kaumaha ultrafine me d60≤2μm (hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha plastik ma hope o ka maloʻo ʻana). Ma ke ʻano laulā, hoʻokahi a ʻelua paha pae o ke kaʻina wili ultra-fine mau e hoʻohana ʻia. ʻO ia hoʻi kahi wili hui pulu a i ʻole ka wili one a me nā pahu mālama a me nā pamu e pili ana.

The production capacity of ordinary heavy calcium in the domestic market has become saturated, and the product price is low, and the technological content and added value are not high. For ultra-fine and active heavy calcium, domestic production capacity cannot meet the demand and still has great market potential. Overall, the main development trends of heavy calcium carbonate industry technology are large-scale, functional and intelligent. This is an inevitable requirement for the intensification, stabilization, structural optimization or specialization of heavy calcium carbonate production, as well as improving production efficiency, reducing energy consumption, wear and tear and reducing production costs. It is also an inevitable requirement for the development of production technology due to the significant increase in market demand and saving the amount of resin in polymer-based composite materials.It is necessary for domestic heavy calcium carbonate companies to learn from the successful experiences of world-famous calcium carbonate companies such as Omya and Imerys, and adopt high-efficiency, energy-saving large-scale equipment and advanced production technology to promote the in-depth development of my country’s heavy calcium carbonate industry in terms of scale and product refinement.As an equipment supplier recognized by Omya, HCM has provided calcium powder processing machinery and equipment to many Omya factories around the world, which are highly praised and favored by customers.
