Heavy calcium carbonate icalcium carbonate poda zvinhu inogadzirwa nemuchina wekupwanya nzira uchishandisa calcite, choko, marble uye mamwe ores semidziyo.Iyo ine hunhu hweyakakura sosi yezvakagadzirwa zvinhu, kuchena kwepamusoro, kukosha kwakaderera kwemafuta, kushandiswa kwakanaka uye mutengo wakaderera.Parizvino ndiyo inonyanya kushandiswa inorganic isiri-metallic mineral powder product ine yakanyanya kushandiswa.

Parizvino, tekinoroji yakanaka yekugadzirisa tekinoroji yeheavy calcium carbonate inonyanya kutarisisa pakukuya uye kuchinjika kwepasi kugadzira zvigadzirwa zvinosangana nezvinodiwa zvehunyoro zvemandima ekushandisa akasiyana, zvinosanganisira hupfu hwakatsetseka, ultrafine powder, surface modified (active) powder uye papermaking slurry zvinosanganisira mapoka akati wandei. uye anopfuura marudzi gumi emhando dzinorema calcium carbonate zvigadzirwa zvine kunaka kwakasiyana uye kugadziridzwa kwepasi uye activation.Saka ndezvipi midziyo inoshandisa calcium carbonate powder?HCM Machinery inyanzvi inozivikanwa yekugadzira calcium poda yekugadzirisa michina nemidziyo muindasitiri.Nhasi tichakuzivisa iwe kune calcium poda yekugadzira michina nemidziyo zvakadzama.

Tsananguro yakadzama yecalcium poda yekugadzira michina nemidziyo:

Ordinary heavy calcium carbonate ine d97≥5μm inonyanya kugadzirwa nenzira yakaoma.Midziyo iyi inosanganisira yakagadziridzwa Raymond mill (yakarembera roller mill kana pendulum mill), roller mill (kusanganisira pressure roller mill/vertical mill, ring roller mill, etc.) neball mill, etc.

Ultrafine heavy calcium carbonate ine d97≥5μm kazhinji inotora kugadzirwa kwakaoma, uye vamwe vanoshandisa kunyorova kugaya + kuomesa maitiro.Kugadzirwa kwakaoma kunonyanya kushandisa dhiramu bhora zvigayo + classifiers, roller mill (kusanganisira ring roller mill ine in-band classification, vertical mill / pressure roller mill), yakaoma yekusanganisa mill + classifiers, nezvimwe.

Papermaking coating giredhi Ultra-fine heavy calcium carbonate slurry ine d97≤5μm, kunyanya d90≤2μm, inowanzo gadzirwa nenzira yekunyorova, uye chishandiso chikuru chigayo chinomutsa uye chigayo chejecha.

Iyo bhora chigayo + classifier yekugadzira mutsara inonyanya kushandiswa kugadzira heavy calcium carbonate poda yakanaka uye ultrafine poda ine d97 = 5 ~ 43μm.Iyo inoratidzwa nekuenderera mberi yakavharwa-yedunhu kugadzirwa, yakawanda-nhanho kupatsanurwa, hombe kutenderera mutoro (300% ~ 500%), uye hombe imwe chete muchina wekugadzira.Mutsetse wekugadzira uyu wakashandiswa kubva pakati-kusvika-kunopera 1990s uye ndeimwe yemhando huru yekugadzira tekinoroji yakakura-yakanyanya-yakanaka inorema calcium carbonate mitsara yekugadzira munyika nhasi.

Ring roller chigayo ndicho chigayo chinoshandiswa zvakanyanya kukuya uye cheultra-fine kugaya mumunda weheavy calcium carbonate kuChina mumakore gumi apfuura.Iyo inoratidzirwa nehukuru hwekupwanya reshiyo uye yakaderera simba rekushandisa pane imwe unit chigadzirwa.Iyo yemukati kana yekunze yakanaka classifier inogona kugadzira zvigadzirwa zvemhando yepamusoro zvine d97≤10μm.Chigadzirwa chakanaka chinogona kugadziriswa pakati pe d97 = 5 ~ 40μm;iyo yakanyatsokodzera chigadzirwa saizi renji ndeye d97 = 10 ~ 30μm.

Roller mill (vertical roller mill/roller mill) ndechimwe chemidziyo mikuru-yakakura yekukuya zvakanaka uye kugaya kweheavy calcium carbonate.Iyo inoratidzirwa nehuwandu hwekupwanya kukuru.Iyo yakanyanya kukodzera chigadzirwa saizi renji ndeye d97 = 15 ~ 45μm.Mushure meiyo yekunze yakanaka classifier yaiswa, inogona kuburitsa zvigadzirwa zvemhando yepamusoro zvine d97≤10μm.Chigadzirwa chacho chine chimiro chakanaka chechidimbu uye yakaderera mafuta absorption kukosha, iyo inonyanya kukodzera kugadzirwa.Unsaturated polyester-based composite materials (artificial stone) inoshandisa heavy calcium carbonate fillers, uye ine simba shoma rekushandisa uye kupfeka pachikamu chimwe chete chigadzirwa.

Wet ultrafine grinding technology inonyanya kushandiswa kugadzira papermaking coating (slurry) giredhi zvigadzirwa zvine d90≤2μm uye d97≤2μm, uye ultrafine heavy calcium carbonate ine d60≤2μm (inoshandiswa sepurasitiki yekuzadza mushure mekuoma).Kazhinji, imwe kana maviri nhanho yekuenderera mberi-yakanaka kugaya nzira inoshandiswa.Iyo inonyanya kuve neyakanyorovesa kusanganisa grinder kana jecha chigayo uye zvinoenderana nekuchengetedza matangi nemapombi.

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.
