Calcium carbonate kev lag luam nrog kev ua haujlwm siab sib xyaw thiab granulating tshuab kev txhim kho thiab nta

Abstract:

Tag nrho cov kev xav tau ntawm cov granulator rau kev lag luam calcium carbonate yog cov thermal efficiency, tsawg zog noj, yooj yim configuration, yooj yim tswj, me me hneev taw, nyab xeeb thiab huv si chaw ua hauj lwm. Tam sim no, kev lag luam ntsev inorganic siv cov khoom siv sib xyaw ua kom muaj txiaj ntsig zoo tshaj plaws: lub tshuab ziab khaub ncaws teb, lub tshuab ziab khaub ncaws tsis ncaj cua sov, lub tshuab ziab khaub ncaws tsis tu ncua, tshuab ziab khaub ncaws...

Calcium carbonate kev lag luam nrog rau tag nrho cov kev xav tau ntawm cov granulator yog siab thermal efficiency, tsis tshua muaj zog noj, yooj yim configuration, yooj yim tswj, me me hneev taw, muaj kev nyab xeeb thiab noj qab nyob zoo chaw ua hauj lwm. Tam sim no, kev lag luam ntsev inorganic siv cov khoom siv sib xyaw ua kom muaj txiaj ntsig zoo tshaj plaws yog: lub raj xa hluav taws xob, lub tshuab hluav taws xob tsis ncaj qha rau lub tshuab ziab khaub ncaws, lub tshuab ziab khaub ncaws tsis tu ncua, tshuab ziab khaub ncaws (tseem muab faib ua pulse airflow, airflow rotary, zoo thiab tsis zoo ntawm lub tshuab ziab khaub ncaws. thib ob airflow drying), rotary flash dryer, rotary drum dryer, spray dryer (tseem muab faib ua granulation, hmoov, centrifugal, siab), vibrating fluidized txaj tshuab, lub tshuab nqus tsev zoo li qub, cua kub ncig qhov cub, rake, slurry dryer Dryer, cua kub ncig qhov cub, rake, slurry nplooj nqus tshuab, boiling tshuab (kab rov tav, ntsug), thiab lwm yam.

Cov kev sib xyaw ua haujlwm siab thiab cov tshuab granulating no muab kev lees paub rau cov khoom lag luam zoo, tab sis muaj teeb meem ntawm cov pa roj sau "plua plav". Vim tias cov khoom lag luam nanoscale nce ntxiv, qhov loj me me ntawm cov khoom qub yog ntau dua thiab zoo dua, muaj peev xwm ya raws cov ntsiab lus ntawm cov ntaub ntawv muab tshuaj txhuam, ua ke nrog kev txhim kho txuas ntxiv ntawm kev lag luam mus rau qhov loj-scale, loj-scale kev taw qhia, cov lag luam tau mob siab rau ua ke siab. -efficiency sib tov thiab granulating tshuab. Tshwj xeeb tshaj yog qee cov khoom loj-tonnage, xws li precipitated calcium carbonate, lub teb chaws tam sim no ntau tshaj 300 lab tons, cov kab ntau lawm txhua xyoo ntawm 10,000 tons, 100,000 tons ntawm nplai rau tsib pawg ntawm high-efficiency mixing thiab granulating tshuab, Guangxi , ib lub lag luam npaj los koom nrog 500,000 tons, raws li qib tam sim no ntawm kev sib xyaw ua haujlwm siab thiab granulating tshuab, tsis hais tus hneev taw ntawm cov khoom siv lossis cov khoom ziab tom qab tus Tsov tus tw roj sau "plua plav" Cov nyiaj ntau heev.

Raws li kev lag luam tam sim no feem ntau siv lub hnab pulse lim, qhov chaw ua haujlwm yog hnyav heev, yuav tsum siv zog ntsuas los daws. Yog li ntawd, peb cia siab tias cov cuab yeej tsim kho kom tsom mus rau kev daws teeb meem ob qho teeb meem, ib qho yog cov ntsiab lus dej siab ntawm cov khoom siv micro-zoo kom qhuav teeb meem, qhov thib ob yog cov khoom tom qab ziab kom qhuav cov khoom "plua plav" muaj teeb meem kev nyiam huv. Calcium carbonate kev lag luam, piv txwv li, ntau tshaj 200 lub lag luam thoob plaws lub teb chaws, nyob rau hauv kev xaiv ntawm high-efficiency sib tov thiab granulating tshuab, siv yooj yim ntawm rotary indirect cua sov tshuab ziab khaub ncaws, nruam disk tshuab ziab khaub ncaws, rotary raj tshuab ziab khaub ncaws, thiab lwm yam. Kev ua tau zoo tau ntsib, kev siv hluav taws xob thiab tso pa tawm "plua plav" tsis zoo tagnrho, calcium carbonate rau hauv kev lag luam, los ntawm hauv av mus rau lub ru tsev yog Ib zaug hauv kev lag luam calcium carbonate, los ntawm hauv av mus rau lub ru tsev yog them nrog ib txheej ntawm dawb calcium carbonate hmoov, txawm nyob rau hauv lub chaw ua hauj lwm ntawm lub rooj thiab lub rooj zaum kuj yog ib txheej ntawm dawb, uas nyob rau hauv ib tes, muaj ib tug kev tswj teeb meem, thiab tseem ceeb tshaj, yog. qhov ziab ntawm cov pa gascollection "plua plav" tsis dhau. Tsis ntev los no, kev lag luam no tau qhia txog cov khoom siv tshem tawm plua plav uas tsim los ntawm DuPont, uas tau daws qhov teeb meem.

Yog li ntawd, kev sib xyaw ua ke ntawm kev sib xyaw ua haujlwm siab thiab cov tshuab granulating yuav tsum muaj xws li: muab cov cuab yeej siv hluav taws xob, ib lossis ob lub tshuab ua haujlwm siab thiab cov tshuab granulating, cov khoom siv "plua plav", thiab lwm yam., Kuv vam tias cov cuab yeej tsim khoom, kev tshawb fawb units. nyob rau hauv lub thermal efficiency, tsawg zog noj, yooj yim configuration, yooj yim rau kev tswj, thiab lwm yam, nyob rau hauv kev sib xyaw ua ke ntawm high-efficiency mixing thiab granulating tshuab ua cov khoom, cov kev pab cuam rau lwm tus, kev loj hlob ntawm kev pab cuam rau lwm tus, kev loj hlob ntawm lawv. tus kheej. Yog tias qhov teeb meem ziab ntawm calcium carbonate kev lag luam raug daws, paub txog kev ua haujlwm siab ntawm cov khoom siv, tus phooj ywg ib puag ncig, lwm yam ntawm cov teeb meem ziab yuav raug daws.
