O le calcium carbonate mamafa o se pa'u calcium carbonate e gaosia e ala i le fa'aaogaina o le calcite, sima, ma'a ma isi minerale e fai ma mea mata. E iai ona uiga o le tele o punaoa o mea mata, maualuga le pa'epa'e, maualalo le aoga o le mitiia o le suau'u, lelei le fa'aaogaina ma taugofie. O le taimi nei o le oloa pa'u minerale e le o ni u'amea e sili ona fa'aaogaina lautele ma e tele le fa'aaogaina.

I le taimi nei, o le tekinolosi fa'agasolo lelei o le calcium carbonate mamafa e taula'i tele i le oloina ma le fa'aleleia o luga e fa'agasolo ai oloa e fetaui ma mana'oga lelei o vaega eseese o fa'aoga, e aofia ai le pauta lelei, pauta ultrafine, pauta fa'aleleia (gaoioi) luga ma le slurry pepa e aofia ai le tele o vaega ma le silia ma le sefulu ituaiga oloa fa'apitoa o le calcium carbonate mamafa ma le eseese o le lelei ma le fa'aleleia ma le fa'agaoioia o luga. O a la meafaigaluega e fa'agasolo ai le pauta calcium carbonate?Masini HCM o se kamupani gaosi oloa lauiloa o masini ma meafaigaluega e gaosi ai le pa'u kalisiu i le alamanuia. O le asō o le a matou fa'ailoa atu ai ia te oe masini ma meafaigaluega e gaosi ai le pa'u kalisiu i auiliiliga.

Fa'amatalaga auiliili o masini ma meafaigaluega e fa'agaoioia ai le pa'u o le calcium:

O le calcium carbonate mamafa masani e iai le d97≥5μm e tele lava ina gaosia e ala i le metotia mago. O masini e aofia ai le Raymond mill ua fa'aleleia (hanging roller mill po'o le pendulum mill), roller mill (e aofia ai le pressure roller mill/vertical mill, ring roller mill, ma isi) ma le ball mill, ma isi.

O le calcium carbonate mamafa tele e iai le d97≥5μm e masani ona faʻaaogaina le faiga o le gaosiga mago, ma o nisi e faʻaaogaina le faiga o le olo susu + faʻamago. O le gaosiga mago e faʻaaogaina tele lava le drum ball mills + classifiers, roller mills (e aofia ai le ring roller mills ma le in-band classification, vertical mills/pressure roller mills), dry mixing mills + classifiers, ma isi.

O le oloina o le calcium carbonate mamafa e matuā lelei le valiina o pepa ma le d97≤5μm, aemaise lava le d90≤2μm, e masani ona gaosia i le auala susu, ma o meafaigaluega autū o se olo fa'agae'e ma se olo oneone.

O le laina gaosiga o le ball mill + classifier e faʻaaogaina tele e gaosia ai le pauta mamafa o le calcium carbonate ma le pauta ultrafine ma le d97=5~43μm. E iloga i le gaosiga faifai pea o le tapunia o le matagaluega, faʻavasegaga e tele-vaega, avega tele o le taamilosaga (300%~500%), ma le tele o le gafatia gaosiga o le masini e tasi. O lenei laina gaosiga ua faʻaaogaina talu mai le ogatotonu o le 1990s ma o se tasi o tekinolosi gaosi autu mo laina gaosiga tetele o le calcium carbonate mamafa ultra-fine i le lalolagi i aso nei.

O le ring roller mill o le masini olo lelei ma le olo manifinifi sili ona faʻaaogaina i le matata o le calcium carbonate mamafa i Saina i le sefulu tausaga ua tuanaʻi. E iloga i le tele o le fua faatatau o le oloina ma le maualalo o le malosi e faʻaaogaina i le iunite oloa. O le faʻavasegaga manifinifi i totonu poʻo fafo e mafai ona gaosia ni oloa manifinifi tele ma le d97≤10μm. E mafai ona fetuʻunaʻi le manifinifi o le oloa i le va o le d97=5~40μm; o le tele o le fasi oloa e sili ona talafeagai o le d97=10~30μm.

O le vili olo (vili olo fa'atulagaina/vili olo) o se tasi o meafaigaluega tetele mo le oloina lelei ma le oloina lelei tele o le calcium carbonate mamafa. E iloga i le tele o le fua faatatau o le oloina. O le tele o le vaega o le oloa e sili ona talafeagai o le d97=15~45μm. A mae'a ona fa'apipi'i se fa'avasega lelei i fafo, e mafai ona gaosia ni oloa lelei tele ma le d97≤10μm. E lelei foliga o le oloa ma e maualalo le mitiia o le suau'u, lea e sili ona talafeagai mo le gaosiga. O mea fa'apipi'i e fa'avae i luga o le polyester unsaturated (ma'a fa'apitoa) e fa'aogaina ai mea fa'atumu mamafa o le calcium carbonate, ma e itiiti le fa'aaogaina o le malosi ma le ofuina i le iunite oloa.

O le tekinolosi oloina manifinifi susu e faʻaaogaina tele e gaosia ai oloa vali pepa (slurry) e iai le d90≤2μm ma le d97≤2μm, ma le calcium carbonate mamafa manifinifi e iai le d60≤2μm (e faʻaaogaina e fai ma faʻatumu palasitika pe a uma ona mago). E masani ona faʻaaogaina le tasi pe lua laʻasaga o le faʻagasologa oloina manifinifi faifai pea. E aofia ai se olo palu susu poʻo se olo oneone ma tane teu ma pamu e fetaui.

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.
