Heavy calcium carbonate ndi calcium carbonate powder material opangidwa ndi makina ophwanyidwa pogwiritsa ntchito calcite, choko, marble ndi miyala ina ngati zipangizo.Ili ndi mawonekedwe a gwero lalikulu la zida zopangira, kuyera kwakukulu, kuyamwa kwamafuta otsika, kugwiritsa ntchito bwino komanso mtengo wotsika.Pakali pano ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pamankhwala osagwiritsa ntchito zitsulo zamchere omwe amagwiritsidwa ntchito kwambiri.

Pakali pano, luso processing bwino wa heavy kashiamu carbonate makamaka lolunjika pa akupera ndi pamwamba kusinthidwa kuti pokonza mankhwala kuti akwaniritse fineness zofunika m'minda ntchito zosiyanasiyana, kuphatikizapo ufa wabwino, ultrafine ufa, pamwamba kusinthidwa (yogwira) ufa ndi papermaking slurry zikuphatikizapo magulu angapo. ndi mitundu yopitilira khumi ya zinthu zapadera zolemetsa za calcium carbonate zokhala ndi fineness yosiyana ndi kusinthidwa kwapansi ndi kuyambitsa.Ndiye ndi zida ziti zomwe zimapanga ufa wa calcium carbonate?Makina a HCM ndi wodziwika bwino wopanga kashiamu ufa processing makina ndi zipangizo mu makampani.Lero tikudziwitsani za makina opangira ufa wa calcium ndi zida mwatsatanetsatane.

Kufotokozera mwatsatanetsatane kashiamu ufa processing makina ndi zipangizo:

Wamba heavy calcium carbonate yokhala ndi d97≥5μm imapangidwa makamaka ndi njira youma.Zipangizozi zikuphatikizapo mphero ya Raymond (yopachika mphero kapena pendulum), mphero (kuphatikizapo pressure roller mill / vertical mill, ring roller mphero, etc. ) ndi mphero ya mpira, ndi zina zotero.

Ultrafine heavy calcium carbonate yokhala ndi d97≥5μm nthawi zambiri imatenga njira yowuma, ndipo ena amagwiritsa ntchito ponyowa akupera + ndi kuyanika.Kupanga zowuma makamaka kumagwiritsa ntchito mphero za ng'oma + magulu, mphero zodzigudubuza (kuphatikiza mphero zodzigudubuza zokhala ndi gulu la in-band, mphero zoyimirira / zopumira), mphero zosakaniza zowuma + magulu, ndi zina.

Papermaking ≤2μm ≤5μm ≤5 ≤5μm, kawirikawiri amapangidwa ndi njira yonyowa, ndipo chida chachikulu ndi mphero yogwedeza ndi mphero yamchenga.

Mzere wopangira mphero + wa classifier umagwiritsidwa ntchito makamaka kupanga heavy calcium carbonate ufa wabwino ndi ultrafine ufa wokhala ndi d97 = 5 ~ 43μm.Amadziwika ndi kupanga kosalekeza kotsekeka, kusanja kwamagawo angapo, katundu wamkulu wozungulira (300% ~ 500%), ndi mphamvu yayikulu yopanga makina amodzi.Mzerewu wakhala ukugwiritsidwa ntchito kuyambira chapakati mpaka kumapeto kwa zaka za m'ma 1990 ndipo ndi imodzi mwamakina opangira makina opangira ma ultra-fine heavy calcium carbonate padziko lapansi masiku ano.

Chigayo cha mphete ndi chida chomwe chimagwiritsidwa ntchito kwambiri pogayira zabwino kwambiri komanso zida zopera bwino kwambiri pantchito ya heavy calcium carbonate ku China m'zaka khumi zapitazi.Amadziwika ndi chiŵerengero chachikulu chophwanyidwa ndi kugwiritsira ntchito mphamvu zochepa pamagulu amtundu uliwonse.Wopanga bwino wamkati kapena wakunja amatha kupanga zinthu zabwino kwambiri zokhala ndi d97≤10μm.The fineness mankhwala akhoza kusintha pakati d97 = 5 ~ 40μm;kukula kwa tinthu koyenera kwambiri ndi d97=10~30μm.

Chigayo chodzigudubuza (odzigudubuza mphero / mphero) ndi chimodzi mwa zida zazikulu zazikulu zopera bwino komanso kupera kwambiri kwa heavy calcium carbonate.Amadziwika ndi chiŵerengero chachikulu chophwanyidwa.Mtundu woyenera kwambiri wa tinthu tating'ono ndi d97 = 15 ~ 45μm.Pambuyo poyika kagulu kabwino kakunja, imatha kupanga zinthu zabwino kwambiri zokhala ndi d97≤10μm.Mankhwalawa ali ndi mawonekedwe abwino a tinthu komanso mtengo wotsika wa mayamwidwe amafuta, omwe ndi oyenera kupanga.Zida zopangidwa ndi polyester zopanda unsaturated (miyala yokumba) zimagwiritsa ntchito zodzaza zolemera za calcium carbonate, ndipo zimakhala ndi mphamvu zochepa komanso zovala pagawo lililonse.

Ukadaulo wogaya wonyowa wa ultrafine umagwiritsidwa ntchito makamaka popanga zinthu zopangira mapepala (slurry) zokhala ndi d90≤2μm ndi d97≤2μm, ndi ultrafine heavy calcium carbonate yokhala ndi d60≤2μm (yomwe imagwiritsidwa ntchito ngati chodzaza pulasitiki mukaumitsa).Nthawi zambiri, gawo limodzi kapena ziwiri zopitilira kugaya bwino kwambiri zimagwiritsidwa ntchito.Zimakhala ndi chonyowa chophatikizira chonyowa kapena mphero yamchenga ndi matanki osungira omwe amafanana ndi mapampu.

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.
