Kev lag luam calcium carbonate nrog kev ua haujlwm siab sib xyaw thiab granulating tshuab kev txhim kho thiab cov yam ntxwv

Abstract:

Cov kev xav tau dav dav ntawm lub tshuab granulator rau kev lag luam calcium carbonate yog kev ua haujlwm thermal zoo, siv hluav taws xob tsawg, teeb tsa yooj yim, tswj tau yooj yim, me me, muaj kev nyab xeeb thiab huv si. Tam sim no, kev lag luam ntsev inorganic siv cov tshuab sib xyaw ua ke zoo dua: lub tshuab ziab raj rotary, lub tshuab ziab cua sov tsis ncaj qha, lub tshuab ziab disk tas mus li, lub tshuab ziab cua ...

Kev lag luam calcium carbonate nrog rau qhov yuav tsum tau ua ntawm lub tshuab granulator yog kev ua haujlwm siab thermal, kev siv hluav taws xob tsawg, kev teeb tsa yooj yim, kev tswj hwm yooj yim, qhov chaw me me, kev nyab xeeb thiab kev noj qab haus huv. Tam sim no, kev lag luam ntsev inorganic siv cov tshuab sib xyaw ua ke siab-ua haujlwm zoo yog: lub tshuab ziab raj rotary, lub tshuab ziab tsis ncaj qha cua sov, lub tshuab ziab disk tas mus li, lub tshuab ziab cua (kuj muab faib ua pulse airflow, airflow rotary, positive thiab negative pressure of the second airflow drying), lub tshuab ziab flash rotary, lub tshuab ziab nruas rotary, lub tshuab ziab tsuag (kuj muab faib ua granulation, hmoov, centrifugal, pressure), lub tshuab ziab vibrating fluidized txaj, lub tshuab ziab nqus tsev, lub tshuab cua kub circulation qhov cub, rake, slurry tshuab ziab, lub tshuab cua kub circulation qhov cub, rake, slurry nplooj nqus tsev ziab, boiling tshuab ziab (kab rov tav, ntsug), thiab lwm yam.

Cov tshuab sib tov thiab granulating no muaj kev lees paub zoo rau cov khoom, tab sis muaj teeb meem ntawm cov pa roj tawm los sau "hmoov av". Vim muaj cov khoom nanoscale ntau ntxiv, qhov loj me ntawm cov khoom qub yog qhov zoo dua, cov dej noo ntawm cov khoom siv nplaum, ua ke nrog kev txhim kho tas mus li ntawm cov lag luam mus rau qhov loj, qhov kev taw qhia loj, cov lag luam xav ua ke cov tshuab sib tov thiab granulating zoo. Tshwj xeeb tshaj yog qee cov khoom loj-tonnage, xws li precipitated calcium carbonate, tam sim no lub teb chaws tsim ntau dua 300 lab tons, cov kab ntau lawm txhua xyoo tsim tawm ntawm 10,000 tons, 100,000 tons ntawm qhov ntsuas rau tsib pawg ntawm cov tshuab sib tov thiab granulating zoo, Guangxi, ib lub tuam txhab npaj yuav koom nrog 500,000 tons, raws li qib tam sim no ntawm cov tshuab sib tov thiab granulating zoo, tsis hais txog qhov chaw ntawm cov khoom siv lossis cov khoom qhuav tom qab sau cov roj "hmoov av" Tus nqi yog loj heev.

Raws li kev lag luam tam sim no feem ntau siv cov lim dej pulse bag, qhov chaw ua haujlwm hnyav heev, yuav tsum siv zog los daws. Yog li ntawd, peb vam tias chav tsim khoom siv yuav tsom mus rau kev daws ob qhov teeb meem, ib qho yog cov dej ntau ntawm cov khoom me me uas ua rau cov khoom qhuav, qhov thib ob yog cov khoom tom qab ziab cov pa phem "hmoov av" teeb meem kev huv huv. Piv txwv li, kev lag luam calcium carbonate, ntau tshaj 200 lub tuam txhab thoob plaws lub tebchaws, hauv kev xaiv cov tshuab sib xyaw thiab granulating siab, kev siv cov tshuab cua sov tsis ncaj qha rotary, lub tshuab ziab disk tas mus li, lub tshuab ziab raj rotary, thiab lwm yam. Txawm hais tias kev ua haujlwm tau zoo tau ua tiav, kev siv hluav taws xob thiab kev sau cov pa phem "hmoov av" tsis zoo tagnrho, calcium carbonate nkag mus rau hauv lub tuam txhab, los ntawm hauv av mus rau lub ru tsev yog Thaum nyob hauv lub tuam txhab calcium carbonate, los ntawm hauv av mus rau lub ru tsev yog them nrog ib txheej ntawm cov hmoov calcium carbonate dawb, txawm tias nyob hauv chaw ua haujlwm ntawm cov rooj thiab cov rooj zaum kuj muaj ib txheej ntawm cov hmoov calcium carbonate dawb, uas ntawm ib sab tes, muaj teeb meem kev tswj hwm, thiab qhov tseem ceeb dua, yog qhov ziab ntawm cov pa phem "hmoov av" 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 feem ntau daws qhov teeb meem.

Yog li ntawd, kev sib xyaw ua ke ntawm cov tshuab sib xyaw ua ke thiab tshuab granulating yuav tsum muaj xws li: muab cov khoom siv cua sov, ib lossis ob lub tshuab sib xyaw ua ke thiab tshuab granulating, cov khoom siv "hmoov av" uas tau sau los ntawm cov pa tawm, thiab lwm yam. Kuv vam tias cov khoom siv tsim khoom, cov chaw tshawb fawb hauv kev ua haujlwm thermal, kev siv hluav taws xob tsawg, kev teeb tsa yooj yim, yooj yim tswj, thiab lwm yam., hauv kev sib xyaw ua ke ntawm cov tshuab sib xyaw ua ke thiab tshuab granulating ua cov khoom, kev pabcuam rau lwm tus, kev txhim kho kev pabcuam rau lwm tus, kev txhim kho lawv tus kheej. Yog tias qhov teeb meem ziab ntawm kev lag luam calcium carbonate raug daws, paub txog kev ua haujlwm zoo ntawm cov khoom siv, tus phooj ywg ib puag ncig, lwm yam teeb meem ziab yuav raug daws.
