I-calcium carbonate enamandla iwuphawuda we-calcium carbonate okhiqizwa ngendlela yokuchoboza ngomshini kusetshenziswa i-calcite, ushoki, imabula kanye nezinye izinto eziyigugu njengezinto zokusetshenziswa. Inezici zomthombo obanzi wezinto zokusetshenziswa, ubumhlophe obuphezulu, inani eliphansi lokumuncwa kwamafutha, ukusebenza okuhle kanye nentengo ephansi. Njengamanje iwumkhiqizo we-inorganic non-metallic mineral powder osetshenziswa kakhulu futhi osetshenziswa kakhulu.

Njengamanje, ubuchwepheshe bokucubungula kahle be-calcium carbonate esindayo bugxile kakhulu ekugayeni nasekuguqulweni kwendawo ukuze kucutshungulwe imikhiqizo ehlangabezana nezidingo zobunono bezinkambu ezahlukene zohlelo lokusebenza, kufaka phakathi i-fine powder, i-ultrafine powder, i-surface modified (esebenzayo) powder kanye ne-papermaking slurry kufaka phakathi izigaba eziningana kanye nezinhlobo ezingaphezu kweshumi zemikhiqizo ekhethekile ye-calcium carbonate esindayo enobunono obuhlukile kanye nokuguqulwa kwendawo kanye nokusebenza. Ngakho-ke yiziphi izinqubo ze-calcium carbonate powder?Imishini ye-HCM ingumkhiqizi odumile wemishini yokucubungula i-calcium powder kanye nemishini embonini. Namuhla sizokwethula ngemishini yokucubungula i-calcium powder kanye nemishini ngokuningiliziwe.

Incazelo eningiliziwe yemishini yokucubungula i-calcium powder kanye nemishini:

I-calcium carbonate evamile esindayo ene-d97≥5μm ikhiqizwa kakhulu ngendlela eyomile. Imishini ihlanganisa umshini wokugaya othuthukisiwe we-Raymond (umshini wokugaya olenga noma umshini wokugaya we-pendulum), umshini wokugaya ojikelezayo (kufaka phakathi umshini wokugaya ocindezelayo/umshini wokugaya oqondile, umshini wokugaya ojikelezayo, njll.) kanye nomshini wokugaya ibhola, njll.

I-calcium carbonate enamandla kakhulu ene-d97≥5μm ngokuvamile isebenzisa inqubo yokukhiqiza eyomile, kanti eminye isebenzisa inqubo yokugaya emanzi + yokomisa. Ukukhiqizwa okomile kusebenzisa kakhulu izigayo zamabhola edrama + izihlukanisi, izigayo zamarola (kufaka phakathi izigayo zamarola ezindandatho ezinezigaba ezingaphakathi, izigayo eziqondile/izigayo zamarola ezicindezelayo), izigayo zokuxuba ezomile + izihlukanisi, njll.

I-slurry ye-calcium carbonate esezingeni eliphezulu kakhulu ene-d97≤5μm, ikakhulukazi i-d90≤2μm, ngokuvamile ikhiqizwa ngendlela emanzi, futhi imishini eyinhloko iyisigayo sokuxubha kanye nesigayo sesihlabathi.

Umugqa wokukhiqiza we-ball mill + classifier usetshenziswa kakhulu ukukhiqiza i-heavy calcium carbonate fine powder kanye ne-ultrafine powder ene-d97=5~43μm. Ibonakala ngokukhiqizwa okuqhubekayo kwe-closed-circuit, ukuhlukaniswa kwezigaba eziningi, umthwalo omkhulu womjikelezo (300%~500%), kanye nomthamo omkhulu wokukhiqiza umshini owodwa. Lo mugqa wokukhiqiza usetshenziswe kusukela maphakathi kuya ekupheleni kwawo-1990 futhi ungomunye wobuchwepheshe obuyinhloko bokukhiqiza imigqa emikhulu yokukhiqiza i-calcium carbonate esindayo ecolekile kakhulu emhlabeni namuhla.

I-ring roller mill iyithuluzi lokugaya elicwebezelayo nelicwebezelayo elisetshenziswa kakhulu emkhakheni we-calcium carbonate esindayo eShayina eminyakeni eyishumi edlule. Libonakala ngesilinganiso esikhulu sokuchoboza kanye nokusetshenziswa kwamandla aphansi ngomkhiqizo ngamunye. I-fine classifier yangaphakathi noma yangaphandle ingakhiqiza imikhiqizo ecwebezelayo ene-d97≤10μm. Ubuncane bomkhiqizo bungalungiswa phakathi kwe-d97=5~40μm; ububanzi bosayizi wezinhlayiya zomkhiqizo obufaneleka kakhulu yi-d97=10~30μm.

I-roller mill (i-vertical roller mill/roller mill) ingenye yemishini emikhulu yokugaya kahle kanye nokugaya kahle kakhulu i-calcium carbonate esindayo. Ibonakala ngesilinganiso esikhulu sokuchoboza. Ububanzi bosayizi wezinhlayiya zomkhiqizo obufanele kakhulu yi-d97=15~45μm. Ngemva kokufakwa kwe-external fine classifier, ingakhiqiza imikhiqizo emihle kakhulu ene-d97≤10μm. Umkhiqizo unesimo esihle sezinhlayiya kanye nenani eliphansi lokumuncwa kwamafutha, okufanelekela kakhulu ukukhiqizwa. Izinto ezihlanganisiwe ezisekelwe ku-polyester engagcwele (itshe lokwenziwa) zisebenzisa ama-filler e-calcium carbonate asindayo, futhi zisebenzisa amandla aphansi kanye nokuguguleka ngomkhiqizo ngamunye.

Ubuchwepheshe bokugaya obusebenzisa i-Wet ultrafine busetshenziswa kakhulu ukukhiqiza imikhiqizo yezinga lokwenza iphepha (slurry) ene-d90≤2μm kanye ne-d97≤2μm, kanye ne-calcium carbonate enamandla kakhulu ene-d60≤2μm (esetshenziswa njenge-plastic filler ngemva kokomiswa). Ngokuvamile, kusetshenziswa isigaba esisodwa noma ezimbili zenqubo yokugaya eqhubekayo. Ngokuyinhloko yakhiwa i-grinder yokuxuba emanzi noma i-sand mill 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.
