Kalsiamu kaboneti nzito ni nyenzo ya unga wa kalsiamu kaboneti inayozalishwa kwa njia ya kusagwa kwa mitambo kwa kutumia kalisiti, chaki, marumaru na madini mengine kama malighafi. Ina sifa za chanzo kikubwa cha malighafi, weupe mwingi, thamani ya chini ya kunyonya mafuta, matumizi mazuri na bei ya chini. Kwa sasa ni bidhaa ya unga wa madini yasiyo ya metali isiyo ya kikaboni inayotumika sana na matumizi makubwa zaidi.

Kwa sasa, teknolojia ya usindikaji laini ya kalsiamu kaboneti nzito inalenga zaidi kusaga na kurekebisha uso ili kusindika bidhaa zinazokidhi mahitaji ya unene wa nyanja tofauti za matumizi, ikiwa ni pamoja na unga laini, unga laini sana, unga uliobadilishwa uso (hai) na tope la kutengeneza karatasi. Inajumuisha kategoria kadhaa na zaidi ya aina kumi za bidhaa maalum za kalsiamu kaboneti nzito zenye unene tofauti na urekebishaji na uanzishaji wa uso. Kwa hivyo ni vifaa gani vinavyosindika unga wa kalsiamu kaboneti?Mashine za HCM ni mtengenezaji maarufu wa mitambo na vifaa vya usindikaji wa unga wa kalsiamu katika tasnia. Leo tutakujulisha kwa kina kuhusu mitambo na vifaa vya usindikaji wa unga wa kalsiamu.

Maelezo ya kina ya mashine na vifaa vya usindikaji wa unga wa kalsiamu:

Kalsiamu kaboneti nzito ya kawaida yenye d97≥5μm huzalishwa zaidi kwa njia kavu. Vifaa hivyo ni pamoja na kinu cha Raymond kilichoboreshwa (kinu cha kunyongwa cha kuzungusha au kinu cha pendulum), kinu cha kuzungusha (ikiwa ni pamoja na kinu cha kuzungusha cha shinikizo/kinu cha wima, kinu cha kuzungusha cha pete, nk.) na kinu cha mpira, nk.

Kalsiamu kaboneti nzito ya ultrafain yenye d97≥5μm kwa ujumla hutumia mchakato wa uzalishaji mkavu, na baadhi hutumia mchakato wa kusaga kwa mvua + kukausha. Uzalishaji mkavu hutumia zaidi vinu vya mpira wa ngoma + viainishaji, vinu vya roller (ikiwa ni pamoja na vinu vya roller vya pete vyenye uainishaji wa ndani ya bendi, vinu vya wima/vinu vya roller vya shinikizo), vinu vya kuchanganya kavu + viainishaji, n.k.

Tope la kalsiamu kaboneti nzito la kiwango cha juu cha upakaji wa karatasi lenye unene wa juu sana lenye d97≤5μm, hasa d90≤2μm, kwa ujumla huzalishwa kwa njia ya mvua, na vifaa vikuu ni kinu cha kukoroga na kinu cha mchanga.

Mstari wa uzalishaji wa kinu cha mpira + uainishaji hutumika zaidi kutengeneza unga mwembamba wa kalsiamu kaboneti nzito na unga mwembamba wa ultrafine wenye d97=5~43μm. Una sifa ya uzalishaji endelevu wa saketi funge, uainishaji wa hatua nyingi, mzigo mkubwa wa mzunguko (300%~500%), na uwezo mkubwa wa uzalishaji wa mashine moja. Mstari huu wa uzalishaji umetumika tangu katikati hadi mwishoni mwa miaka ya 1990 na ni mojawapo ya teknolojia kuu za uzalishaji kwa mistari mikubwa ya uzalishaji wa kalsiamu kaboneti nzito yenye ultrafine duniani leo.

Kinu cha kusaga chenye pete ndicho kifaa kinachotumika sana cha kusaga laini na cha kusaga laini sana katika uwanja wa kalsiamu kaboneti nzito nchini China katika miaka kumi iliyopita. Kina sifa ya uwiano mkubwa wa kusaga na matumizi ya chini ya nishati kwa kila kitengo cha bidhaa. Kiainisha laini cha ndani au cha nje kinaweza kutoa bidhaa laini sana zenye d97≤10μm. Unene wa bidhaa unaweza kurekebishwa kati ya d97=5~40μm; kiwango kinachofaa zaidi cha ukubwa wa chembe ya bidhaa ni d97=10~30μm.

Kinu cha kusaga (kinu cha kusaga wima/kinu cha kusaga) ni mojawapo ya vifaa vikuu vikubwa vya kusaga laini na kusaga laini sana kwa kalsiamu kaboneti nzito. Kina sifa ya uwiano mkubwa wa kusagwa. Aina ya ukubwa wa chembe ya bidhaa inayofaa zaidi ni d97=15~45μm. Baada ya kiainishaji laini cha nje kusakinishwa, kinaweza kutoa bidhaa laini sana zenye d97≤10μm. Bidhaa hiyo ina umbo zuri la chembe na thamani ndogo ya kunyonya mafuta, ambayo inafaa hasa kwa uzalishaji. Vifaa vya mchanganyiko vyenye msingi wa polyester isiyoshibishwa (jiwe bandia) hutumia vijazaji vizito vya kalsiamu kaboneti, na vina matumizi ya chini ya nishati na uchakavu kwa kila bidhaa ya kitengo.

Teknolojia ya kusaga laini sana hutumika zaidi kutengeneza bidhaa za kiwango cha kutengeneza karatasi (tope) zenye d90≤2μm na d97≤2μm, na kalsiamu kaboneti nzito laini sana yenye d60≤2μm (hutumika kama kijazaji cha plastiki baada ya kukausha). Kwa ujumla, hatua moja au mbili za mchakato endelevu wa kusaga laini sana hutumiwa. Kimsingi ina kisaga cha kuchanganya kwa maji au kinu cha mchanga na matangi na pampu zinazolingana za kuhifadhi.

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.
