Imishini yokucubungula i-calcium powder kanye nokuhlaziywa kokugeleza kwenqubo yemishini

I-Heavy calcium carbonate i-calcium carbonate powder material ekhiqizwa ngendlela yokuchoboza ngomshini isebenzisa i-calcite, ushoki, imabula nezinye izinto ezinsimbi.Inezici zomthombo obanzi wezinto zokusetshenziswa, ubumhlophe obuphezulu, inani eliphansi lokumunca uwoyela, ukusebenziseka okuhle kanye nentengo ephansi.Njengamanje iwumkhiqizo osetshenziswa kakhulu we-inorganic non-metallic mineral powder osetshenziswa kakhulu.

Njengamanje, ubuchwepheshe bokucutshungulwa okuhle kwe-heavy calcium carbonate ikakhulukazi bugxile ekugayeni nasekuguqulweni komhlaba ukuze kucutshungulwe imikhiqizo ehlangabezana nezidingo zokucoleka kwezinkambu ezihlukene zokufaka isicelo, okuhlanganisa impushana ecolekile, i-ultrafine powder, i-surface modified (esebenzayo) powder kanye ne-papermaking slurry ihlanganisa izigaba eziningana. kanye nezinhlobo ezingaphezu kweshumi zemikhiqizo ekhethekile ye-calcium carbonate enobunono obuhlukile nokulungiswa kwendawo nokwenziwa kusebenze.Ngakho-ke yiziphi izinto ezisebenza nge-calcium carbonate powder?Imishini ye-HCM ungumkhiqizi owaziwayo wemishini yokucubungula i-calcium powder kanye nemishini embonini.Namuhla sizokwethula ngemishini yokucubungula i-calcium powder kanye nemishini ngokuningiliziwe.

 

Incazelo enemininingwane yemishini yokucubungula i-calcium powder kanye nemishini:

I-calcium carbonate enzima evamile ene-d97≥5μm ikhiqizwa kakhulu ngendlela eyomile.Imishini ihlanganisa isigayo sikaRaymond esithuthukisiwe (isigayo esilengayo noma isigayo se-pendulum), isigayo se-roller (kuhlanganise nesigayo se-pressure roller/i-vertical mill, i-ring roller mill, njll.) kanye ne-ball mill, njll.

 

I-Ultrafine heavy calcium carbonate ene-d97≥5μm ngokuvamile yamukela inqubo yokukhiqiza eyomile, futhi abanye basebenzisa inqubo yokugaya okumanzi + yokomisa.Ukukhiqizwa okomile kusebenzisa kakhulu izigayo zebhola lezigubhu + izihlukanisi, izigayo zamarola (okuhlanganisa izigayo zamarola anezigaba ezingaphakathi kwebhendi, izigayo eziqondile/izigayo zokucindezela), izigayo zokuxuba ezomile + izihlukanisi, njll.

 

Ibanga le-papermaking grade ultra-fine heavy calcium carbonate slurry ene-d97≤5μm, ikakhulukazi i-d90≤2μm, ngokuvamile ikhiqizwa ngendlela emanzi, futhi okokusebenza okuyinhloko umshini wokugaya onyakazayo nomshini wesihlabathi.

 

Ulayini wokukhiqiza we-ball Mill + classifier usetshenziswa kakhulu ukukhiqiza impushana enhle ye-calcium carbonate ne-ultrafine powder ene-d97=5~43μm.Ibonakala ngokukhiqizwa kwesekethe evaliwe okuqhubekayo, ukuhlukaniswa kwezigaba eziningi, umthwalo omkhulu womjikelezo (300% ~ 500%), namandla okukhiqiza umshini owodwa omkhulu.Lo mzila wokukhiqiza usetshenziswe kusukela maphakathi nawo-1990s kuya ngasekupheleni kwawo-1990 futhi ungobunye bobuchwepheshe bokukhiqiza obuyinhloko bemigqa yokukhiqiza ye-ultra-fine esindayo ye-calcium carbonate emhlabeni wonke namuhla.

 

I-ring roller Mill iwumshini wokugaya ocolisekileyo osetshenziswa kakhulu kanye ne-ultra-fine emkhakheni we-heavy calcium carbonate e-China eminyakeni eyishumi edlule.Ibonakala ngesilinganiso esikhulu sokuchotshozwa kanye nokusetshenziswa kwamandla okuphansi ngomkhiqizo weyunithi ngayinye.Isigaba sangaphakathi noma sangaphandle esihle singakhiqiza imikhiqizo emihle kakhulu ene-d97≤10μm.Ukuqina komkhiqizo kungalungiswa phakathi kwe-d97=5~40μm;uhla losayizi wezinhlayiyana ofaneleka kakhulu ngu-d97=10~30μm.

 

I-roller mill (i-vertical roller mill/roller mill) ingenye yemishini emikhulu emikhulu yokugaya kahle kanye nokugaywa kwe-ultra-fine ye-heavy calcium carbonate.Ibonakala ngesilinganiso esikhulu sokuchotshozwa.Ibanga elifaneleka kakhulu likasayizi wezinhlayiyana ngu-d97=15~45μm.Ngemva kokufakwa kwesigaba esihle sangaphandle, singakhiqiza imikhiqizo emihle kakhulu ene-d97≤10μm.Umkhiqizo unomumo omuhle wezinhlayiyana kanye nenani eliphansi lokumunca uwoyela, elifaneleka ngokukhethekile ukukhiqizwa.Izinto eziyinhlanganisela ezisekelwe ku-polyester ezingafakwanga (itshe lokwenziwa) zisebenzisa izihlungi ezisindayo ze-calcium carbonate, futhi zisebenzisa amandla aphansi futhi zigugile umkhiqizo ngamunye weyunithi.

 

Ubuchwepheshe bokugaya be-ultrafine obumanzi busetshenziselwa ikakhulukazi ukukhiqiza imikhiqizo yebanga le-papermaking coating (slurry) ene-d90≤2μm kanye ne-d97≤2μm, kanye ne-ultrafine heavy calcium carbonate ene-d60≤2μm (esetshenziswa njengesigcwalisi sepulasitiki ngemva kokoma).Ngokuvamile, kusetshenziswa isigaba esisodwa noma ezimbili zenqubo yokugaya ecolekile kakhulu.Ikakhulukazi iqukethe umshini wokugaya omanzi noma umshini wesihlabathi kanye namathangi okugcina ahambisanayo namaphampu.

 

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.
