ʻO ka calcium carbonate kaumaha kahi mea pauka calcium carbonate i hana ʻia e ke kaʻina hana mīkini e hoʻohana ana i ka calcite, chalk, marble a me nā ores ʻē aʻe e like me nā mea maka.Loaʻa iā ia nā hiʻohiʻona o ke kumu ākea o nā mea maka, keʻokeʻo kiʻekiʻe, haʻahaʻa ka waiwai absorption ʻaila, hoʻohana maikaʻi a me ke kumu kūʻai haʻahaʻa.ʻO ia ka mea i hoʻohana nui ʻia i kēia manawa ka mea hoʻohana nui ʻole i ka pauka mineral non-metallic me ka ʻai nui loa.

I kēia manawa, ʻo ka ʻenehana hana maikaʻi o ka calcium carbonate kaumaha ka mea nui i ka wili ʻana a me ka hoʻololi ʻana i ka ʻili e hoʻoponopono i nā huahana e kū ana i nā koi o nā ʻano noiʻi like ʻole, me ka pauka maikaʻi, ka pauka ultrafine, ka pauka i hoʻololi ʻia (active) a me ka slurry papermaking. a ʻoi aku ma mua o ʻumi mau ʻano huahana calcium carbonate koʻikoʻi me ka maikaʻi like ʻole a me ka hoʻololi ʻana a me ka hoʻōla ʻana.No laila he aha nā mea hana e hana ai i ka pauka calcium carbonate?Mīkini HCM he mea hana kaulana o ka mīkini hoʻoheheʻe pauka calcium a me nā mea hana i ka ʻoihana.I kēia lā mākou e hoʻolauna iā ʻoe i ka mīkini hoʻoheheʻe pauka calcium a me nā mea kikoʻī.

ʻO ka wehewehe kikoʻī o nā mīkini hoʻoheheʻe calcium pauka a me nā mea hana:

Hoʻopuka nui ʻia ka calcium carbonate kaumaha me ka d97≥5μm ma ke ʻano maloʻo.Aia nā mea hana i ka wili Raymond i hoʻomaikaʻi ʻia (mill roller mill a i ʻole pendulum mill), wili wili (me ka wili puʻupuʻu / wili kūpaʻa, wili wili apo, a me nā mea ʻē aʻe) a me ka wili pōleʻa, etc.

Hoʻohana maʻamau ʻo Ultrafine heavy calcium carbonate me d97≥5μm i ke kaʻina hana maloʻo, a hoʻohana kekahi i ka wili pulu + kaʻina hoʻomaloʻo.Hoʻohana nui ʻia ka hana maloʻo i nā wili pahu pahu + classifiers, roller mills (me ka hui pū ʻana me ka hoʻokaʻawale ʻana i loko o ka band, nā wili paʻa a me nā wili puʻupuʻu), nā wili hui maloʻo + classifiers, etc.

ʻO ka slurry kalapona kalapona kaumaha nui me ka d97≤5μm, ʻoi aku ka d90≤2μm, hana pinepine ʻia ma ke ʻano pulu, a ʻo ka mea nui he wili hoʻoulu a me kahi wili one.

Hoʻohana nui ʻia ka mill mill + classifier production line e hana i ka calcium carbonate fine pauka a me ka pauka ultrafine me d97 = 5 ~ 43μm.Hōʻike ʻia ia e ka hoʻomau ʻana i ka hana kaapuni paʻa, ka hoʻokaʻawale ʻana i nā pae he nui, ka ukana nui (300% ~ 500%), a me ka mana hana mīkini hoʻokahi.Ua hoʻohana ʻia kēia laina hana mai ka waena o ka makahiki 1990 a ʻo ia kekahi o nā ʻenehana hana nui no nā laina hana calcium carbonate kaumaha nui loa i ka honua i kēia lā.

ʻO ka mīkini wili liʻiliʻi ka mea hoʻohana nui loa i ka wili maikaʻi a me nā mea wili maikaʻi loa ma ke kahua o ka calcium carbonate kaumaha ma Kina i nā makahiki he ʻumi i hala.Hōʻike ʻia ia e ka lākiō kuʻi nui a me ka hoʻohana ʻana i ka ikehu haʻahaʻa no kēlā me kēia huahana.Hiki i ka mea hoʻohālikelike maikaʻi i loko a i waho paha ke hana i nā huahana ultra-fine me d97≤10μm.Hiki ke hoʻololi i ka fineness huahana ma waena o d97 = 5 ~ 40μm;ʻO ka nui o ka nui o nā huahana kūpono loa he d97 = 10 ~ 30μm.

ʻO ka wili wili (vertical roller mill/roller mill) kekahi o nā mea hana nui nui no ka wili maikaʻi a me ka wili maikaʻi loa o ka calcium carbonate kaumaha.Hōʻike ʻia ʻo ia e ka lākiō kuʻi nui.ʻO ka nui o ka nui o nā huahana kūpono ʻo d97 = 15 ~ 45μm.Ma hope o ka hoʻokomo ʻia ʻana o kahi papa helu maikaʻi o waho, hiki iā ia ke hana i nā huahana ultra-fine me d97≤10μm.Loaʻa i ka huahana ke ʻano ʻāpana maikaʻi a me ka waiwai absorption ʻaila haʻahaʻa, kahi kūpono no ka hana ʻana.Hoʻohana ʻia nā mea i hoʻohui ʻia i ka polyester i hoʻopaʻa ʻole ʻia (pōhaku hana ʻia) i nā mea hoʻopiha calcium carbonate kaumaha, a he haʻahaʻa ka hoʻohana ʻana i ka ikehu a me ka lole o kēlā me kēia huahana.

Hoʻohana nui ʻia ka ʻenehana wet ultrafine grinding no ka hana ʻana i ka uhi pepa (slurry) i nā huahana papa me d90≤2μm a me d97≤2μm, a me ka ultrafine kaumaha calcium carbonate me d60≤2μm (hoʻohana ʻia e like me ka hoʻopihapiha plastik ma hope o ka maloʻo ʻana).ʻO ka maʻamau, hoʻohana ʻia hoʻokahi a ʻelua paha mau ʻanuʻu o ka hana wili ultra-fine mau.Loaʻa ka nui o ka mīkini hui ʻana a i ʻole ka wili one a me nā pahu hoʻopaʻa a me nā pamu.

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.
