Kaalshiyam culus oo kaarboonat ah waa walax budada kaarboonat ee kaalshiyam ah oo laga soo saaro habka burburinta farsamada iyadoo la adeegsanayo kalsiyum, nuurad, marmar iyo macdano kale oo ah walxo cayriin ah. Waxay leedahay astaamo ay ka mid yihiin ilo ballaaran oo walxo cayriin ah, caddaan sare, qiimo nuugid saliid oo hooseeya, ku habboonaan wanaagsan iyo qiimo jaban. Hadda waa badeecada ugu badan ee budada macdanta aan dabiiciga ahayn ee aan biraha ahayn ee loo isticmaalo iyadoo la isticmaalo ugu badan.

Waqtigan xaadirka ah, tiknoolajiyada farsamaynta fiican ee kaalshiyamka culus ee kaalshiyamka ayaa inta badan diiradda saarta shiididda iyo wax ka beddelka dusha sare si loo farsameeyo alaabada buuxisa shuruudaha qurxinta ee goobaha kala duwan ee codsiga, oo ay ku jiraan budada wanaagsan, budada ultrafine, budada dusha sare ee wax laga beddelay (firfircoon) iyo slurry-ka sameynta waraaqaha waxaa ku jira dhowr qaybood iyo in ka badan toban nooc oo ah alaabada gaarka ah ee kaalshiyamka culus ee kaalshiyamka oo leh hagaajin kala duwan iyo wax ka beddelka dusha sare iyo kicinta. Haddaba qalabkee ayaa farsameeya budada kaalshiyamka ee kaalshiyamka?Makiinadaha HCM waa shirkad caan ku ah soo saarista iyo qalabka lagu farsameeyo budada kalsiyum ee warshadaha. Maanta waxaan si faahfaahsan kuugu soo bandhigi doonnaa mashiinnada iyo qalabka lagu farsameeyo budada kalsiyum.

Sharaxaad faahfaahsan oo ku saabsan mashiinnada iyo qalabka wax lagu farsameeyo budada kalsiyum:

Kaarboonatka calcium-ka culus ee caadiga ah oo leh d97≥5μm waxaa inta badan lagu soo saaraa habka qalalan. Qalabka waxaa ka mid ah mashiinka Raymond ee la hagaajiyay (warshadda duubista ee laalaada ama mashiinka pendulum-ka), mashiinka duubista (oo ay ku jiraan mashiinka duubista cadaadiska/warshadda toosan, mashiinka duubista giraanta, iwm.) iyo mashiinka kubbadda, iwm.

Kaarboonat calcium culus oo aad u fiican oo leh d97≥5μm guud ahaan waxay qaadataa habka wax soo saarka qalalan, qaarna waxay isticmaalaan habka shiididda qoyan + qalajinta. Wax soo saarka qalalan wuxuu inta badan isticmaalaa mishiinnada kubbadda durbaanka + kala-soocidda, mishiinnada duubista (oo ay ku jiraan mishiinnada duubista giraanta oo leh kala-soocidda kooxda dhexdeeda, mishiinnada toosan/mashiinnada duubista cadaadiska), mishiinnada isku-darka qalalan + kala-soocidda, iwm.

Dahaarka warqadda ee heerka sare ah ee dahaadhka culus ee calcium carbonate oo leh d97≤5μm, gaar ahaan d90≤2μm, guud ahaan waxaa lagu soo saaraa hab qoyan, qalabka ugu muhiimsanna waa warshad walaaqaysa iyo warshad ciid ah.

Khadka wax soo saarka ee mashiinka kubbadda iyo kala-soocidda waxaa inta badan loo isticmaalaa in lagu soo saaro budada calcium carbonate ee culus iyo budada ultrafine oo leh d97=5~43μm. Waxaa lagu gartaa wax soo saar joogto ah oo wareegsan, kala-soocid marxalado badan leh, culays wareeg oo weyn (300%~500%), iyo awood wax soo saar hal mashiin oo weyn. Khadkan wax soo saarka waxaa la isticmaalay tan iyo bartamihii ilaa dhammaadkii 1990-meeyadii waana mid ka mid ah teknoolojiyada wax soo saarka ugu weyn ee khadadka wax soo saarka calcium carbonate ee aadka u fiican ee adduunka maanta.

Mashiinka shiididda giraanta waa qalabka shiididda ugu fiican uguna fiican ee loo isticmaalo warshadaha kaarboonatka calcium ee culus ee Shiinaha tobankii sano ee la soo dhaafay. Waxaa lagu gartaa saamiga burburinta weyn iyo isticmaalka tamarta oo hooseeya ee halbeeg kasta. Kala-soocidda khafiifka ah ee gudaha ama dibadda waxay soo saari kartaa badeecooyin aad u fiican oo leh d97≤10μm. Tayada badeecadda waxaa lagu hagaajin karaa inta u dhaxaysa d97=5~40μm; cabbirka walxaha ugu habboon ee badeecaddu waa d97=10~30μm.

Mashiinka Roller-ka (mashiinka roller-ka toosan/mashiinka roller-ka) waa mid ka mid ah qalabka ugu weyn ee loogu talagalay shiididda wanaagsan iyo shiididda aadka u fiican ee kaalshiyamka culus ee kaalshiyamka. Waxaa lagu gartaa saamiga burburinta weyn. Kala duwanaanshaha cabbirka walxaha badeecada ugu habboon waa d97 = 15 ~ 45μm. Ka dib marka la rakibo kala-soocid khafiif ah oo dibadda ah, waxay soo saari kartaa badeecooyin aad u fiican oo leh d97≤10μm. Badeecadu waxay leedahay qaab walax oo wanaagsan iyo qiimo nuugid saliid oo hooseeya, taas oo si gaar ah ugu habboon wax soo saarka. Alaabada isku-dhafka ah ee ku salaysan polyester-ka aan buuxin (dhagax macmal ah) waxay isticmaalaan buuxinta kaalshiyamka culus ee kaalshiyamka, waxayna leeyihiin isticmaalka tamarta oo hooseeya iyo xirashada halbeeg kasta.

Tiknoolajiyadda shiididda ultrafine-ka qoyan waxaa inta badan loo isticmaalaa in lagu soo saaro alaabada heerka sameynta dahaarka warqadda (slurry) oo leh d90≤2μm iyo d97≤2μm, iyo kaalshiyam culus oo ultrafine ah oo leh d60≤2μm (loo isticmaalo buuxinta balaastikada ka dib qalajinta). Guud ahaan, hal ama laba marxaladood oo ah habka shiididda aadka u fiican ayaa la isticmaalaa. Waxay inta badan ka kooban tahay shiidiye isku darka qoyan ama warshad ciid ah iyo haamaha kaydinta iyo bambooyin u dhigma.

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.
