Carbonate nzito ya kalsiamu ni nyenzo ya poda ya kalsiamu ya kalsiamu inayozalishwa na njia ya kusagwa ya mitambo kwa kutumia calcite, chaki, marumaru na ore zingine kama malighafi. Inayo sifa ya chanzo pana cha malighafi, weupe wa juu, thamani ya chini ya kunyonya mafuta, utumiaji mzuri na bei ya chini. Kwa sasa ni bidhaa inayotumika zaidi ya madini ya madini isiyo ya metali na matumizi makubwa zaidi.

Kwa sasa, teknolojia nzuri ya usindikaji wa kaboni nzito kaboni inazingatia sana kusaga na muundo wa uso kusindika bidhaa zinazokidhi mahitaji kamili ya uwanja tofauti wa maombi, pamoja na poda laini, poda ya ultrafine, poda iliyobadilishwa (inayotumika) na papermaking inajumuisha vikundi kadhaa na zaidi ya aina kumi ya bidhaa maalum za kalsiamu kalsiamu na laini tofauti na muundo wa uso na uanzishaji. Kwa hivyo ni vifaa gani vinasindika poda ya kalsiamu ya kalsiamu?Mashine ya HCM ni mtengenezaji anayejulikana wa mashine ya usindikaji wa poda ya kalsiamu na vifaa kwenye tasnia. Leo tutakutambulisha kwa mashine ya usindikaji wa poda ya kalsiamu na vifaa kwa undani.

Maelezo ya kina ya mashine za usindikaji wa poda ya kalsiamu na vifaa:

Carbonate ya kawaida ya kalsiamu nzito na D97≥5μm inazalishwa hasa na njia kavu. Vifaa hivyo ni pamoja na kuboresha Raymond Mill (Hanging Roller Mill au Pendulum Mill), Roller Mill (pamoja na shinikizo roller Mill/wima Mill, Gonga Roller Mill, nk) na Mill ya Mpira, nk.

Ultrafine nzito kalsiamu kaboni na D97≥5μm kwa ujumla huchukua mchakato wa uzalishaji kavu, na wengine hutumia mchakato wa kukausha + kukausha. Uzalishaji kavu hutumia mill ya mpira wa ngoma + classifiers, mill ya roller (pamoja na mill ya roller na uainishaji wa ndani ya bendi, mills ya wima/mill ya shinikizo), mill ya mchanganyiko wa kavu + classifiers, nk.

Papermaking mipako ya kiwango cha juu cha kalsiamu nzito kalsiamu kaboni na D97≤5μm, haswa D90≤2μm, kwa ujumla hutolewa na njia ya mvua, na vifaa kuu ni kinu cha kuchochea na kinu cha mchanga.

Mstari wa uzalishaji wa kinu cha mpira + hutumiwa hasa kutengeneza poda nzito ya kalsiamu kaboni na poda ya ultrafine na D97 = 5 ~ 43μm. Ni sifa ya uzalishaji unaoendelea wa mzunguko, 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 ya miaka ya 1990 na ni moja wapo ya teknolojia kuu za uzalishaji kwa mistari mikubwa ya uzalishaji wa kalsiamu nzito ulimwenguni leo.

Pete Roller Mill ndio vifaa vya kusaga vizuri na vya kusaga-laini katika uwanja wa kaboni nzito kaboni nchini China katika miaka kumi iliyopita. Ni sifa ya uwiano mkubwa wa kusagwa na matumizi ya chini ya nishati kwa bidhaa ya kitengo. Darasa la ndani au la nje linaweza kutoa bidhaa za mwisho na D97≤10μm. Ukweli wa bidhaa unaweza kubadilishwa kati ya D97 = 5 ~ 40μm; Aina inayofaa zaidi ya chembe ya bidhaa ni D97 = 10 ~ 30μm.

Roller Mill (wima Roller Mill/Roller Mill) ni moja ya vifaa vikubwa vya kusaga laini na kusaga kwa laini ya kaboni nzito ya kalsiamu. Ni sifa ya uwiano mkubwa wa kusagwa. Aina inayofaa zaidi ya chembe ya bidhaa ni D97 = 15 ~ 45μm. Baada ya darasa la faini ya nje kusanikishwa, inaweza kutoa bidhaa za mwisho na D97≤10μm. Bidhaa hiyo ina sura nzuri ya chembe na thamani ya chini ya kunyonya mafuta, ambayo inafaa sana kwa uzalishaji. Vifaa vyenye msingi wa polyester-msingi (jiwe bandia) hutumia vichungi vizito vya kaboni, na kuwa na matumizi ya chini ya nishati na kuvaa kwa bidhaa ya kitengo.

Teknolojia ya kusaga ya maji ya mvua hutumiwa sana kutengeneza bidhaa za daraja la papermaking (slurry) na D90≤2μM na D97≤2μM, na kaboni nzito ya kalsiamu na D60≤2μm (inayotumika kama filler ya plastiki baada ya kukausha). Kwa ujumla, hatua moja au mbili za mchakato unaoendelea wa kusaga-fine hutumiwa. Ni hasa ya grinder ya mchanganyiko wa mvua au kinu cha mchanga na mizinga inayofanana ya kuhifadhi na pampu.

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.
