Calcium carbonate wolemera kwambiri ndi ufa wa calcium carbonate wopangidwa ndi njira yophwanyira makina pogwiritsa ntchito calcite, choko, marble ndi miyala ina ngati zopangira. Uli ndi mawonekedwe a gwero lalikulu la zopangira, kuyera kwambiri, mafuta ochepa kuyamwa, kugwiritsidwa ntchito bwino komanso mtengo wotsika. Pakadali pano ndi ufa wa mchere wosapangidwa ndi zinthu zachilengedwe womwe umagwiritsidwa ntchito kwambiri ndipo umagwiritsidwa ntchito kwambiri.

Pakadali pano, ukadaulo wokonza bwino wa heavy calcium carbonate umayang'ana kwambiri pakugaya ndi kusintha pamwamba kuti zinthu zigwirizane ndi zofunikira za fineness m'magawo osiyanasiyana ogwiritsira ntchito, kuphatikiza ufa wosalala, ufa wosalala kwambiri, ufa wosinthidwa pamwamba (wogwira ntchito) ndi slurry yopanga mapepala imaphatikizapo magulu angapo ndi mitundu yoposa khumi ya zinthu zapadera za calcium carbonate zolemera zokhala ndi fineness yosiyana komanso kusintha pamwamba ndi kuyambitsa. Ndiye ndi zipangizo ziti zomwe zimapanga ufa wa calcium carbonate?Makina a HCM ndi kampani yodziwika bwino yopanga makina ndi zida zopangira ufa wa calcium mumakampani. Lero tikudziwitsani mwatsatanetsatane za makina ndi zida zopangira ufa wa calcium.

Kufotokozera mwatsatanetsatane kwa makina ndi zida zopangira ufa wa calcium:

Kalisiyumu carbonate wamba wolemera wokhala ndi d97≥5μm umapangidwa makamaka pogwiritsa ntchito njira youma. Zipangizozi zimaphatikizapo mphero yabwino ya Raymond (mphero yopachika kapena mphero ya pendulum), mphero yopukutira (kuphatikiza mphero yopukutira/mphero yowongoka, mphero yopukutira, ndi zina zotero) ndi mphero yopukutira, ndi zina zotero.

Kalisiyumu wolemera kwambiri wa calcium carbonate wokhala ndi d97≥5μm nthawi zambiri umagwiritsa ntchito njira yopangira youma, ndipo ena amagwiritsa ntchito njira yopukutira yonyowa + youma. Kupanga kouma kumagwiritsa ntchito makamaka ma mphero a mpira wa ng'oma + ma classifiers, ma roller mills (kuphatikiza ma ring roller mills okhala ndi gulu la in-band, ma vertical mills/pressure roller mills), ma dry mixing mills + ma classifiers, ndi zina zotero.

Chopaka mapepala chopangidwa ndi calcium carbonate cholemera kwambiri chokhala ndi d97≤5μm, makamaka d90≤2μm, nthawi zambiri chimapangidwa ndi njira yonyowa, ndipo zida zazikulu ndi mphero yosakaniza ndi mphero yamchenga.

Mzere wopanga mill mill + classifier umagwiritsidwa ntchito makamaka popanga ufa wolemera wa calcium carbonate ndi ufa wa ultrafine wokhala ndi d97=5~43μm. Umadziwika ndi kupanga kosalekeza kwa ma closed-circuit, kugawa magawo ambiri, kunyamula katundu wambiri (300%~500%), komanso mphamvu yayikulu yopangira makina amodzi. Mzere wopanga uwu wakhala ukugwiritsidwa ntchito kuyambira pakati mpaka kumapeto kwa zaka za m'ma 1990 ndipo ndi umodzi mwa ukadaulo waukulu wopanga mizere yayikulu yolemera kwambiri ya calcium carbonate padziko lonse lapansi masiku ano.

Mphero yopukutira mphete ndi chipangizo chopukutira chopepuka kwambiri chomwe chimagwiritsidwa ntchito kwambiri pakupanga calcium carbonate yolemera ku China m'zaka khumi zapitazi. Chimadziwika ndi chiŵerengero chachikulu cha kuphwanya ndi kugwiritsa ntchito mphamvu zochepa pa chinthu chilichonse. Chogawa chamkati kapena chakunja cha fine chimatha kupanga zinthu zabwino kwambiri zokhala ndi d97≤10μm. Kupyapyala kwa chinthucho kumatha kusinthidwa pakati pa d97=5~40μm; kukula kwa tinthu tating'onoting'ono toyenera kwambiri ndi d97=10~30μm.

Chopukusira chopukusira (chopukusira choyimirira/chopukusira chopukusira) ndi chimodzi mwa zida zazikulu zopukusira ndi kupukusira calcium carbonate yolemera kwambiri. Chimadziwika ndi chiŵerengero chachikulu chopukusira. Kukula kwa tinthu tating'onoting'ono toyenera kwambiri ndi d97=15~45μm. Pambuyo poti chopukusira chakunja chayikidwa, chimatha kupanga zinthu zabwino kwambiri zokhala ndi d97≤10μm. Chopukusiracho chili ndi mawonekedwe abwino a tinthu tating'onoting'ono komanso mafuta ochepa, zomwe ndizofunikira kwambiri popanga. Zipangizo zopangidwa ndi polyester zosakhuta (miyala yopangira) zimagwiritsa ntchito zodzaza calcium carbonate zolemera, ndipo zimakhala ndi mphamvu zochepa komanso kusowa kwa mphamvu pa chinthu chilichonse.

Ukadaulo wopukusira wa Wet Ultrafine umagwiritsidwa ntchito makamaka popanga zinthu zopangira mapepala okhala ndi d90≤2μm ndi d97≤2μm, ndi calcium carbonate wolemera kwambiri wokhala ndi d60≤2μm (wogwiritsidwa ntchito ngati pulasitiki wodzaza ukauma). Nthawi zambiri, gawo limodzi kapena awiri a njira yopukusira yopitilira bwino kwambiri amagwiritsidwa ntchito. Makamaka imakhala ndi chopukusira chonyowa kapena mphero yamchenga ndi matanki osungira ndi mapampu ofananira.

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.
