Kabonat kalsyòm lou se yon materyèl an poud kabonat kalsyòm ki pwodui pa metòd kraze mekanik lè l sèvi avèk kalsit, lakrè, mab ak lòt minrè kòm matyè premyè. Li gen karakteristik sous matyè premyè laj, gwo blanchite, valè absòpsyon lwil ki ba, bon aplikabilite ak pri ki ba. Kounye a, li se pwodwi an poud mineral inòganik ki pa metalik ki pi lajman itilize ak pi gwo konsomasyon an.

Kounye a, teknoloji pwosesis rafinman kabonat kalsyòm lou a sitou konsantre sou fanm k'ap pile ak modifikasyon sifas pou trete pwodwi ki satisfè egzijans rafinman diferan domèn aplikasyon yo, tankou poud rafinman, poud ultrafin, poud modifye sifas (aktif) ak sispansyon pou fè papye ki gen ladan plizyè kategori ak plis pase dis kalite pwodwi espesyal kabonat kalsyòm lou ak diferan rafinman ak modifikasyon ak aktivasyon sifas. Alò, ki ekipman ki trete poud kabonat kalsyòm lan?Machin HCM se yon manifakti byen koni nan machin ak ekipman pou pwosesis poud kalsyòm nan endistri a. Jodi a nou pral prezante w machin ak ekipman pou pwosesis poud kalsyòm an detay.

Eksplikasyon detaye sou machin ak ekipman pou pwosesis poud kalsyòm:

Kabonat kalsyòm lou òdinè ak d97≥5μm pwodui sitou pa metòd sèk. Ekipman an gen ladan l moulen Raymond amelyore (moulen woulo pandye oswa moulen pandil), moulen woulo (ki gen ladan moulen woulo presyon/moulen vètikal, moulen woulo bag, elatriye) ak moulen boul, elatriye.

Kabonat kalsyòm lou ultrafin ak d97≥5μm jeneralman itilize pwosesis pwodiksyon sèk, epi gen kèk ki itilize pwosesis fanm mouye + siye. Pwodiksyon sèk la sitou itilize moulen boul tanbou + klasifikatè, moulen woulo (ki gen ladan moulen woulo bag ak klasifikasyon nan-band, moulen vètikal/moulen woulo presyon), moulen melanje sèk + klasifikatè, elatriye.

Anjeneral, yo pwodui yon melanj kabonat kalsyòm lou ultra-fin pou fè papye ak yon d97≤5μm, sitou d90≤2μm, pa metòd mouye, epi ekipman prensipal la se yon moulen brase ak yon moulen sab.

Liy pwodiksyon moulen boul + klasifikatè a sitou itilize pou pwodui poud amann kabonat kalsyòm lou ak poud ultrafin ak d97=5~43μm. Li karakterize pa pwodiksyon kontinyèl sikwi fèmen, klasifikasyon plizyè etap, gwo chaj sik (300%~500%), ak gwo kapasite pwodiksyon yon sèl machin. Liy pwodiksyon sa a te itilize depi mitan rive nan fen ane 1990 yo epi li se youn nan prensipal teknoloji pwodiksyon pou liy pwodiksyon kabonat kalsyòm lou ultrafin sou gwo echèl nan mond lan jodi a.

Moulen woulo bag la se ekipman pou fanm k'ap pile amann ak fanm k'ap pile ultra-amann ki pi lajman itilize nan domèn kabonat kalsyòm lou nan Lachin nan dis dènye ane yo. Li karakterize pa yon gwo rapò kraze ak yon konsomasyon enèji ki ba pou chak inite pwodwi. Klasifikatè amann entèn oswa ekstèn lan ka pwodui pwodwi ultra-amann ak d97≤10μm. Rafineman pwodwi a ka ajiste ant d97=5~40μm; ranje gwosè patikil pwodwi ki pi apwopriye a se d97=10~30μm.

Moulen woulo (moulen woulo vètikal/moulen woulo) se youn nan prensipal ekipman gwo echèl pou fanm k'ap pile byen ak fanm k'ap pile ultra-fin kabonat kalsyòm lou. Li karakterize pa yon gwo rapò kraze. Gwosè patikil pwodwi ki pi apwopriye a se d97=15~45μm. Apre yo fin enstale yon klasifikatè amann ekstèn, li ka pwodui pwodwi ultra-fin ak d97≤10μm. Pwodwi a gen yon bon fòm patikil ak yon valè absòpsyon lwil ki ba, ki patikilyèman apwopriye pou pwodiksyon. Materyèl konpoze ki baze sou Polyester ensature (wòch atifisyèl) itilize ranpli kabonat kalsyòm lou, epi yo gen yon konsomasyon enèji ak yon usure ki ba pou chak inite pwodwi.

Teknoloji broyage ultrafin mouye a sitou itilize pou pwodui pwodwi kouch papye (sispansyon) ak d90≤2μm ak d97≤2μm, ak kabonat kalsyòm lou ultrafin ak d60≤2μm (yo itilize li kòm yon ranplasman plastik apre siye). Anjeneral, yo itilize youn oubyen de etap nan yon pwosesis broyage ultrafin kontinyèl. Li konsiste sitou de yon moulen melanj mouye oubyen yon moulen sab ak tank depo ak ponp ki koresponn yo.

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.
