I-Heavy calcium carbonate yimathiriyeli ye-calcium carbonate powder eveliswa yindlela yokutyumza ngoomatshini kusetyenziswa i-calcite, itshokhwe, ibhastile kunye nezinye izinto ezikrwada njengezinto ezikrwada.Ineempawu zomthombo obanzi wezinto eziluhlaza, ubumhlophe obuphezulu, ixabiso eliphantsi lokufunxa ioli, ukusetyenziswa kakuhle kunye nexabiso eliphantsi.Okwangoku yeyona mveliso isetyenziswa kakhulu kwi-inorganic non-metallic powder powder esetyenziswa kakhulu.

Okwangoku, itekhnoloji yokucubungula itekhnoloji ye-heavy calcium carbonate igxile kakhulu ekusileni kunye nokuguqulwa komhlaba ukuze kuqhutywe iimveliso ezihlangabezana neemfuno ze-fineness yeendawo ezahlukeneyo zesicelo, kubandakanywa umgubo ococekileyo, umgubo we-ultrafine, umphezulu oguqulwayo (osebenzayo) umgubo kunye ne-papermaking slurry ibandakanya iindidi ezininzi. kunye neentlobo ezingaphezu kweshumi zeemveliso ezikhethekileyo ze-calcium carbonate ezinobuhle obahlukeneyo kunye nokuguqulwa komphezulu kunye nokusebenza.Ngoko zeziphi izixhobo eziqhuba i-calcium carbonate powder?HCM oomatshini ngumvelisi owaziwayo we-calcium powder processing oomatshini kunye nezixhobo kushishino.Namhlanje siza kukwazisa ngoomatshini bokwenza umgubo wecalcium kunye nezixhobo ngokweenkcukacha.

Inkcazo eneenkcukacha zoomatshini bokwenza umgubo wecalcium kunye nezixhobo:

I-calcium carbonate eqhelekileyo ene-d97≥5μm iveliswa ikakhulu yindlela eyomileyo.Izixhobo ziquka ukuphuculwa kweRaymond mill (i-hanging roller mill okanye i-pendulum mill), i-roller mill (kubandakanywa i-pressure roller mill / i-vertical mill, i-ring roller mill, njl. njl.) kunye ne-ball mill, njl.

I-Ultrafine heavy calcium carbonate ene-d97≥5μm ngokubanzi ithatha inkqubo yokuvelisa eyomileyo, kwaye abanye basebenzisa inkqubo yokusila emanzi + yokumisa.Imveliso eyomileyo isebenzisa ikakhulu i-drum ball mill + classifiers, i-roller mills (kubandakanywa i-ring roller mills ene-in-band classification, i-vertical mills / i-pressure roller mill), i-mills yokuxuba okomileyo + abahluli, njl.

I-Papermaking ibakala lokugquma i-ultra-fine heavy calcium carbonate slurry ene-d97≤5μm, ingakumbi i-d90≤2μm, iveliswa ngokubanzi ngendlela emanzi, kwaye isixhobo esiphambili sisisila esishukumisayo kunye nesanti yokusila.

I-ball mill + classifier umgca wemveliso isetyenziselwa kakhulu ukuvelisa i-calcium carbonate powder enzima kunye ne-ultrafine powder kunye ne-d97 = 5 ~ 43μm.Ibonakaliswa ngokuqhubekayo kokuveliswa kweesekethe ezivaliweyo, ukuhlelwa kwamanqanaba amaninzi, umthwalo omkhulu wokujikeleza (300% ~ 500%), kunye nomthamo omkhulu wokuvelisa umatshini omnye.Lo mgca wemveliso usetyenziswe ukusukela phakathi ukuya kutsho ekupheleni kweminyaka yoo-1990 kwaye yenye yezona teknoloji ziphambili zemveliso yemigca yokuvelisa i-calcium carbonate enkulu emhlabeni namhlanje.

Iringi yokusila sesona sixhobo sisetyenziswa kakhulu sokusila esicolekileyo kunye nesixhobo sokusila se-ultra-fine kwintsimi ye-heavy calcium carbonate e-China kule minyaka ilishumi idlulileyo.Ibonakaliswa ngumlinganiselo omkhulu wokutyumza kunye nokusetyenziswa kwamandla aphantsi kwimveliso yeyunithi.I-classifier yangaphakathi okanye yangaphandle ye-fine iyakwazi ukuvelisa iimveliso ze-ultra-fine kunye ne-d97≤10μm.Ukulungiswa kwemveliso kunokulungelelaniswa phakathi kwe-d97 = 5 ~ 40μm;eyona mveliso ifanelekileyo yobungakanani boluhlu lwesayizi yi-d97=10~30μm.

I-roller mill (i-roller mill / i-roller mill) sesinye sezixhobo eziphambili zobukhulu obukhulu bokugaya kunye ne-ultra-fine yokusila i-heavy calcium carbonate.Ibonakaliswa ngumlinganiselo omkhulu wokutyumza.Olona luhlu lufanelekileyo lobungakanani bamasuntswana yi-d97=15~45μm.Emva kokuba kufakwe umdidi ocoliweyo wangaphandle, unokuvelisa iimveliso ze-ultra-fine nge-d97≤10μm.Imveliso inesimo esihle samasuntswana kunye nexabiso eliphantsi lokufunxa ioli, elifaneleke ngokukodwa ukuveliswa.Izinto ezihlanganisiweyo ze-polyester-based based composite (ilitye lokufakelwa) zisebenzisa i-heavy calcium carbonate fillers, kwaye zisebenzise amandla aphantsi kunye nokugqoka kwimveliso nganye yeyunithi.

Itekhnoloji yokugaya i-ultrafine emanzi isetyenziselwa ukuvelisa i-papermaking coating (slurry) iimveliso zebakala kunye ne-d90≤2μm kunye ne-d97≤2μm, kunye ne-ultrafine enzima ye-calcium carbonate ene-d60≤2μm (esetyenziswa njenge-plastic filler emva kokumisa).Ngokuqhelekileyo, inqanaba elinye okanye ezimbini zenkqubo yokugaya i-ultra-fine eqhubekayo isetyenziswa.Ikakhulu iqulethe i-grinder yokuxuba emanzi okanye i-sand mill kunye neetanki zokugcina ezihambelanayo kunye neepompo.

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.
