Kev loj hlob ntawmaluminium dross xovxwm systemsyog ib qho tseem ceeb heev rau kev lag luam aluminium. Txoj kev no nrog kev nqis peev tsawg thiab cov txiaj ntsig ceev tau coj ntau txoj kev yooj yim rau kev lag luam txhuas, txhim kho kev ua haujlwm zoo thiab ua kom cov khoom zoo tib lub sijhawm, nws tuaj yeem tswj kev lag luam ntse, ua haujlwm sai ntawm txhuas dross, txo kev tuav haujlwm thiab ntxiv kom muaj kev nyab xeeb. ntawm qhov chaw smelting.
● Txhim kho txhuas rov qab los ntawm Dross
Cov txiaj ntsig tseem ceeb ntawm dross presses yog enormously ntxiv tsim aluminium recuperation contrasted nrog phau ntawv detachment. Xovxwm yog tsim los txhim kho ciam teb xws li kub, siab, qhov loj, lub sij hawm hauv tsev thiab lub voj voog kom nthuav dav aluminium extraction los ntawm dross.
Cov yam tseem ceeb xws li kev siv lub siab nruj, kev sib tsoo zoo ntawm cov khoom, ua kom sov lub zog kom soften aluminium, thiab ntau lub voj voog squeezing empower recuperation tus nqi ntau tshaj 60%. Vim muaj kev txwv nyob rau hauv exposing nplua txhuas particles encased nyob rau hauv dross aggregates, phau ntawv raking thiab tshuaj ntsuam txoj kev, ntawm qhov tod tes, tsuas yog ua tiav 20-30% rov qab.
Siab duaAluminium Dross Press Systemsncaj nraim mus rau qhov txo qis aluminium hmoov phem thiab txo qis dross tshem tawm ntim. Qhov no txuag nyiaj ntawm cov nqi pov tseg thiab cov nqi ntawm cov khoom siv raw. Dross presses ntseeg tau tsim cov ncuav qab zib kawg nkaus nrog tsuas yog 3-8% tshuav ntawm txhuas sib piv nrog 15-20% rau cov tswv yim ntawm phau ntawv. Zuag qhia tag nrho, dross presses tuaj yeem ua rau txhuas rov qab uas yog 2-3 zaus ntau dua li ntawm kev sib cais ntawm phau ntawv.
● Txo cov nqi khiav lag luam
Aluminium Dross Press Systemstsis tsuas yog nce aluminium yields, tab sis lawv kuj txo cov nqi khiav lag luam. Txoj cai tawm ntawm tus puav, kev sib cuam tshuam hauv computer ua haujlwm tsawg dua qhov yuav tsum tau ua ua ntej los ntawm ib puag ncig 5-6 cov neeg ua haujlwm rau txhua qhov kev hloov pauv rau phau ntawv qhia rau tsuas yog 1-2 cov thawj coj rau kab xovxwm dross . HR cov nqi raug txo qis los ntawm kev ua haujlwm qis dua.
Tsis tas li ntawd, rov siv dua kev ntsuas siab dua ntawm cov khoom siv txhuas rov qab los ntawm dross ua rau cov nqi hluav taws xob qis dua. Dissolving reused hlau yuav tsum tsuas yog 5-10% ntawm lub zog rau qhov tseem ceeb txhuas tsim . Txhua tonne ntawm cov ntaub ntawv rov qab tau txais txiaj ntsig hauv kev txuag hluav taws xob tseem ceeb.
Thirdly, npaj cov nqi qis ntawm cov khoom tsis yog xim hlau ua kom txo tau cov nqi pov tseg. Tsawg pov tseg xaus rau hauv qhov chaw pov tseg thaum aluminium rov qab siab dua. Feem ntau, dross presses tuaj yeem ua rau ntau tshaj li ib nrab ntawm cov nqi ua haujlwm txuas nrog rau kev ua haujlwm, lub zog thiab kev tshem tawm cov khib nyiab.
● Ib puag ncig Sustainability
Sustainability tau dhau los ua qhov tseem ceeb rau aluminium smelters. Los ntawm kev rov ua dua tshiab thiab txo cov pov tseg,aluminium dross xovxwm systemsua kom muaj kev txhim kho tseem ceeb hauv cov metrics sustainability ua tau.
Txij li thaum rov ua dua txhuas txuag tau ntau dua 90% ntawm CO2 emissions piv rau thawj txhuas, rov zoo dua li nkim txhuas txo cov pa roj carbon monoxide ntau lawm. Greenhouse gas emissions txo thaum cov nqi rov ua dua.
Tsis tas li ntawd, kev rov ua dua tshiab feem ntau ntawm cov txhuas rov qab tau ua rau cov khib nyiab tsawg dua mus rau hauv qhov chaw pov tseg. Tsis txhob muab pov tseg rau hauv av, compacted dross residue tuaj yeem ua tiav rau hauv cov ntaub ntawv tseem ceeb xws li cement additives.
Tsis tas li ntawd, robotizing lub recuperation kev sib cuam tshuam ntxiv txhim kho kev ruaj ntseg los ntawm kev tshem tawm phau ntawv tiv tauj nrog dross txaus ntshai. Los ntawm thiab loj, dross presses tso cai rau cov neeg tsim khoom txhuas kom ua tau raws li lub hom phiaj kev txhawb nqa txuas nrog cov hlau rov qab, cov dej ntws tawm, thiab pov tseg.
Hauv kev xaus,aluminium dross xovxwm systemsmuab cov txiaj ntsig tseem ceeb xws li nce kev ruaj khov, txo cov nqi, thiab nce aluminium yields. Dross presses yog ib qho kev daws teeb meem tseem ceeb rau cov neeg tsim khoom niaj hnub txhuas kom rov qab tau tus nqi los ntawm cov teeb meem pov tseg, muab qhov zoo rau kev lag luam thiab ib puag ncig.
