Cov roj carbonate hnyav yog cov calcium carbonate hmoov cov khoom siv los ntawm cov tshuab, chalk, marble thiab lwm yam ores ua cov khoom nyoos. Nws muaj cov yam ntxwv ntawm dav cov ntaub ntawv ntawm cov khoom siv raw, zoo dawb, cov roj nqus tau zoo, siv tau zoo thiab tus nqi qis. Nws yog tam sim no qhov dav tshaj plaws siv inorganic tsis yog xim hlau ntxhia cov khoom lag luam nrog cov kev siv ntau tshaj plaws.

Tam sim no, kev ua kom zoo ntawm cov roj carbonate hnyav yog txhawm rau ua cov txheej txheem zoo, suav nrog cov hmoov uas zoo, ua kom zoo thiab papermaking slurry muaj ntau pawg Thiab ntau tshaj kaum yam tshwj xeeb calcium cov khoom lag luam carbonate tshwj xeeb nrog txawv fineness thiab kev hloov kho saum npoo thiab ua kom ua. Yog li cov cuab yeej siv calcium carbonate hmoov?HCM tshuab Yog cov chaw tsim khoom muaj npe zoo ntawm calcium hmoov ua tshuab thiab cov cuab yeej hauv kev lag luam. Niaj hnub no peb yuav qhia koj kom calcium hmoov ua tshuab thiab khoom siv hauv kev nthuav dav.

Cov ncauj lus kom ntxaws piav qhia ntawm calcium hmoov ua tshuab thiab khoom siv:

Cov teeb meem hnyav hnyav calcium carbonate nrog D97≥5μm yog feem ntau tsim los ntawm cov qauv qhuav. Cov cuab yeej siv suav nrog kev txhim kho Raymond zeb (dai cov menyuam zeb lossis cov menyuam zeb (suav nrog cov pob zeb zeb (suav nrog cov menyuam zeb, ntiv tes zeb, thiab cov pob zeb, thiab lwm yam.

Ultrafine hnyav calcium carbonate nrog d97≥5μm Feem ntau adopts qhuav cov txheej txheem ntau lawm, thiab qee qhov siv ntub cov txheej txheem sib tsoo + kev ua kom qhuav. Qhuav ntau ntau yog siv nruas pob zeb mills + classifiers, ntsug classic, siab mills + classifiers, thiab lwm yam.

Papermermaking txheej qib Ultra-nplua cov roj carbonate hnyav

Cov pob zeb + cov kab classifier ntau lawm yog siv los tsim cov calcium carbonate hmoov thiab ultrasfine hmoov nrog D97 = 5 ~ 43μm. Nws yog tus cwj pwm los ntawm kev sib txuas lus sib txuas-corrcuit Court, muaj ntau theem kev faib tawm, lub voj voog loj (300% ~ 500%), thiab cov tshuab loj ntau lawm. Cov kab ntau lawm tau siv txij li thaum nruab nrab-rau-lig kev sib tw thev naus laus zis ntau lawm roj av ntau lawm hauv ntiaj teb niaj hnub no.

Ntiv nplhaib cov menyuam zeb yog qhov kev sib tsoo zoo tshaj plaws thiab ultra-nplua sib tsoo hauv lub tshav pob ntawm cov calcium carbonate hauv Suav teb hauv kaum xyoo dhau los. Nws yog tus cwj pwm los ntawm qhov loj crushing sib thiab tsis tshua muaj zog siv ib yam khoom. Sab hauv lossis sab nraud nplua classifier muaj peev xwm tsim cov khoom lag luam ultra zoo nrog d97≤10μ m. Cov khoom lag luam muaj peev xwm tuaj yeem hloov kho ntawm D97 = 5 ~ 40μm; Qhov khoom lag luam uas tsim nyog tshaj plaws yog D97 = 10 ~ 30μm.

Cov menyuam zeb (Ntsug cov menyuam zeb / cov menyuam zeb) yog ib qho ntawm cov khoom loj loj rau kev sib tsoo kom zoo thiab ultra-nplua sib tsoo ntawm calcium carbonate. Nws yog tus cwj pwm los ntawm cov sib npaug loj. Qhov khoom lag luam uas tsim nyog tshaj plaws yog D97 = 15 ~ 45μm. Tom qab sab nraud ntawm cov neeg nyob sab nraud nyob sab nraud yog ntsia, nws tuaj yeem tsim cov khoom siv roj nrog d97≤10μμm. Cov khoom muaj cov qauv zoo thiab cov roj tsis taus roj, uas yog tsim tshwj xeeb rau kev tsim khoom. Cov khoom siv tsis tau muaj polyester uas tsis tau sib xyaw ua ke (lub pob zeb dag) siv cov roj carbonate carbonate thiab hnav qis zog siv hluav taws xob thiab hnav ib qho khoom lag luam.

Ntub ultrafine sib tsoo tshuab feem ntau yog siv los tsim cov ntawv sau ntxiv (slurrine) cov khoom lag luam calcium carbonate nrog d60. Feem ntau, ib lossis ob theem ntawm cov txheej txheem sib tsoo tshiab ultra-nplua yog siv. Nws tsuas yog muaj cov kev sib xyaw ntub dej sib xyaw lossis xuab zeb zeb thiab cov tso tsheb hlau luam thiab cov twj tso kua mis cia.

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.
