Hnyav calcium carbonate yog cov khoom siv calcium carbonate uas tsim los ntawm kev siv tshuab crushing siv calcite, chalk, marble thiab lwm yam ores ua raw khoom.Nws muaj cov yam ntxwv ntawm qhov dav ntawm cov khoom siv raw, siab dawb, tsis tshua muaj roj nqus tus nqi, siv tau zoo thiab tus nqi qis.Tam sim no nws yog qhov siv ntau tshaj plaws inorganic non-metallic ntxhia hmoov cov khoom lag luam nrog kev noj ntau tshaj plaws.

Tam sim no, kev ua haujlwm zoo ntawm cov calcium carbonate hnyav feem ntau yog tsom rau kev sib tsoo thiab kev hloov kho saum npoo rau cov txheej txheem cov khoom uas ua tau raws li qhov yuav tsum tau ua ntawm cov ntawv thov sib txawv, suav nrog cov hmoov zoo, ultrafine hmoov, nto hloov kho (active) hmoov thiab papermaking slurry suav nrog ntau pawg. thiab ntau tshaj kaum yam tshwj xeeb hnyav calcium carbonate cov khoom uas sib txawv fineness thiab deg hloov kho thiab ua kom.Yog li dab tsi cov cuab yeej ua cov calcium carbonate hmoov?HCM Machinery yog lub chaw tsim khoom lag luam paub zoo ntawm calcium hmoov ua tshuab thiab khoom siv hauv kev lag luam.Niaj hnub no peb yuav qhia koj txog calcium hmoov ua machinery thiab cov khoom kom ntxaws.

Cov ntsiab lus piav qhia ntawm calcium hmoov ua tshuab thiab khoom siv:

Ordinary hnyav calcium carbonate nrog d97≥5μm yog tsim los ntawm txoj kev qhuav.Cov cuab yeej muaj xws li kev txhim kho Raymond zeb (duab cov menyuam zeb los yog pendulum zeb), cov menyuam zeb (xws li lub siab rau cov menyuam zeb / ntsug zeb, lub nplhaib cov menyuam zeb, thiab lwm yam) thiab pob zeb, thiab lwm yam.

Ultrafine hnyav calcium carbonate nrog d97≥5μm feem ntau siv cov txheej txheem qhuav qhuav, thiab qee qhov siv ntub sib tsoo + txheej txheem ziab.Qhuav ntau lawm mas siv nruas pob mills + classifiers, cov menyuam mills (xws li lub nplhaib rau cov menyuam mills nrog nyob rau hauv-band faib, ntsug mills / siab cov menyuam mills), qhuav mixing mills + classifiers, thiab lwm yam.

Papermaking txheej qib ultra-fine hnyav calcium carbonate slurry nrog d97≤5μm, tshwj xeeb tshaj yog d90≤2μm, feem ntau yog tsim los ntawm txoj kev ntub dej, thiab cov khoom siv tseem ceeb yog lub tshuab nplawm thiab xuab zeb zeb.

Lub pob zeb + classifier ntau lawm kab yog tsuas yog siv los tsim hnyav calcium carbonate hmoov zoo thiab ultrafine hmoov nrog d97 = 5 ~ 43μm.Nws yog tus cwj pwm los ntawm kev tsim hluav taws xob txuas ntxiv, kev faib tawm ntau theem, lub voj voog loj loj (300% ~ 500%), thiab lub peev xwm loj ib lub tshuab ntau lawm.Cov kab ntau lawm no tau siv txij li nruab nrab mus txog rau thaum xyoo 1990s thiab yog ib qho ntawm cov thev naus laus zis tseem ceeb rau cov kab loj loj ultra-fine hnyav calcium carbonate ntau lawm kab hauv ntiaj teb niaj hnub no.

Ring roller mill yog cov khoom siv sib tsoo zoo tshaj plaws thiab cov khoom siv sib tsoo zoo tshaj plaws hauv kev ua haujlwm hnyav calcium carbonate hauv Suav teb hauv kaum xyoo dhau los.Nws yog tus cwj pwm los ntawm qhov loj crushing piv thiab tsawg zog noj ib chav tsev khoom.Lub sab hauv lossis sab nraud zoo classifier tuaj yeem tsim cov khoom zoo nrog d97≤10μm.Cov khoom zoo tuaj yeem hloov kho ntawm d97 = 5 ~ 40μm;Cov khoom tsim nyog tshaj plaws yog d97 = 10 ~ 30μm.

Cov menyuam zeb ( ntsug cov menyuam zeb / cov menyuam zeb) yog ib qho ntawm cov khoom siv loj loj rau kev sib tsoo zoo thiab kev sib tsoo ntawm cov calcium carbonate hnyav.Nws yog characterized los ntawm ib tug loj crushing piv.Cov khoom tsim nyog tshaj plaws yog d97 = 15 ~ 45μm.Tom qab cov txheej txheem zoo sab nraud raug teeb tsa, nws tuaj yeem tsim cov khoom zoo nrog d97≤10μm.Cov khoom muaj zoo particle zoo thiab tsis tshua muaj roj nqus tus nqi, uas yog tshwj xeeb tshaj yog haum rau ntau lawm.Unsaturated polyester-based composite cov ntaub ntawv (xws li pob zeb) siv hnyav calcium carbonate fillers, thiab muaj tsawg zog noj thiab hnav ib chav tsev khoom.

ntub ultrafine sib tsoo tshuab yog tsuas yog siv los tsim papermaking txheej (slurry) qib khoom nrog d90≤2μm thiab d97≤2μm, thiab ultrafine hnyav calcium carbonate nrog d60≤2μm (siv raws li yas muab tub lim tom qab ziab).Feem ntau, ib lossis ob theem ntawm kev sib tsoo ultra-nplua txuas txuas ntxiv yog siv.Nws yog tsim los ntawm cov khoom sib xyaw ntub dej los yog cov xuab zeb zeb thiab sib xyaw cov tso tsheb hlau luam thiab cov twj tso kua mis.

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.
