Lub nplhaib tuag straw pellet tshuab yog cov cuab yeej tseem ceeb ntawm cov txheej txheem biomass roj pellet, thiab lub nplhaib tuag yog qhov tseem ceeb ntawm lub nplhaib tuag straw pellet tshuab, thiab nws kuj yog ib qho yooj yim hnav feem ntau ntawm lub nplhaib tuag straw. tshuab pellet.Kawm txog cov laj thawj ntawm lub nplhaib tuag tsis ua haujlwm, txhim kho kev siv lub nplhaib tuag, txhim kho cov khoom zoo thiab cov khoom tsim tawm, txo kev siv hluav taws xob (granulation zog siv nyiaj rau 30% mus rau 35% ntawm tag nrho lub zog noj ntawm tag nrho cov rhiav), thiab txo cov khoom siv cov nqi (ntiv nplhaib tuag poob ib qho Tus nqi ntawm qhov project tso nyiaj ntau dua 25% mus rau 30% ntawm cov nqi kho kom zoo nkauj ntawm tag nrho cov khoom tsim khoom rhiav) thiab muaj kev cuam tshuam zoo.

1. Kev ua haujlwm ntawm lub nplhaib tuag pellet tshuab

Lub nplhaib tuag yog tsav los tig los ntawm lub cev muaj zog los ntawm lub reducer.Lub tshuab nias ntsia tau rau hauv lub nplhaib tuag tsis tig, tab sis tig ntawm nws tus kheej vim kev sib txhuam nrog lub nplhaib tig tuag (los ntawm cov khoom siv compacting).Cov ntaub ntawv quenched thiab tempered nkag mus rau hauv lub xovxwm chamber yog sib npaug ntawm cov xovxwm chais los ntawm cov kis tau tus mob, clamped thiab squeezed los ntawm nias chais, thiab tsis tu ncua extruded los ntawm qhov tuag qhov ntawm lub nplhaib tuag los tsim columnar hais thiab ua raws li lub nplhaib tuag.Lub nplhaib yog tig, thiab cov roj biomass granular ntawm ib qho ntev yog txiav los ntawm ib tug cutter fixedly ntsia sab nraum lub nplhaib tuag.Txoj kab ceev ntawm lub nplhaib tuag thiab lub nip yob yog tib yam ntawm txhua qhov chaw ntawm kev sib cuag, thiab tag nrho nws cov siab yog siv rau pelletizing.Hauv cov txheej txheem ua haujlwm ntawm lub nplhaib tuag, ib txwm muaj kev sib txhuam ntawm lub nplhaib tuag thiab cov khoom siv.Raws li tus nqi ntawm cov khoom tsim tau nce, lub nplhaib tuag maj mam hnav thiab nws thiaj li ua tsis tiav.Daim ntawv no npaj siab los tshuaj xyuas qhov ua tsis tiav ua rau lub nplhaib tuag, thiaj li ua cov lus qhia txog kev tsim khoom thiab siv cov xwm txheej ntawm lub nplhaib tuag.

2. Kev tshuaj xyuas tsis ua haujlwm ua rau lub nplhaib tuag

Los ntawm qhov kev xav ntawm qhov tseeb tsis ua haujlwm tshwm sim ntawm lub nplhaib tuag, nws tuaj yeem muab faib ua peb pawg.Thawj hom: Tom qab lub nplhaib tuag tau ua hauj lwm rau ib lub sij hawm, lub puab phab ntsa ntawm txhua qhov me me ntawm cov khoom yog hnav tawm, txoj kab uas hla ntawm lub qhov nce, thiab cov particle txoj kab uas hla ntawm lub granular biomass roj ntau tshaj qhov. teev tus nqi thiab ua tsis tau;hom thib ob: Tom qab lub puab phab ntsa ntawm lub nplhaib tuag yog hnav, lub puab nto Qhov tsis sib xws yog qhov hnyav, uas cuam tshuam cov ndlwg ntawm cov roj biomass, thiab cov paug tawm txo qis thiab tsis siv;hom thib peb: tom qab lub puab phab ntsa ntawm lub nplhaib tuag yog hnav, lub puab txoj kab uas hla nce thiab phab ntsa thickness txo, thiab cov phab ntsa sab hauv ntawm lub qhov tso tawm kuj hnav nrog cov hnav., yog li ntawd cov phab ntsa thickness ntawm lub qhov tso tawm yog tsis tu ncua txo, yog li cov txheej txheem lub zog txo.Ua ntej txoj kab uas hla ntawm qhov tso tawm qhov nce mus rau qhov tso cai tau teev tseg (uas yog, ua ntej thawj hom kev ua tsis tiav tshwm sim), nyob rau hauv qhov txaus ntshai Cracks thawj zaug tshwm sim ntawm ntu ntu thiab txuas ntxiv mus kom txog thaum cov kab nrib pleb txuas mus rau qhov loj dua. range thiab lub nplhaib tuag ua tsis tiav.Cov laj thawj tseem ceeb ntawm peb qhov tsis ua tiav saum toj no tuaj yeem suav tau tias yog kev hnav ua ntej, ua raws li kev qaug zog tsis ua haujlwm.

2-1 Abrasive hnav

Muaj ntau qhov laj thawj rau hnav, uas tau muab faib ua ib txwm hnav thiab hnav tsis zoo.Lub ntsiab yog vim li cas rau ib txwm hnav yog cov qauv ntawm cov khoom, lub crushing particle loj, thiab quenching thiab tempering zoo ntawm cov hmoov.Nyob rau hauv cov xwm txheej hnav ib txwm, lub nplhaib tuag yuav tsum hnav zoo ib yam nyob rau hauv axial kev taw qhia, ua rau lub qhov tuag loj dua thiab cov phab ntsa nyias nyias.Cov laj thawj tseem ceeb rau kev coj txawv txawv yog: lub siab rau cov menyuam raug kho kom nruj heev, thiab qhov sib txawv ntawm cov menyuam thiab lub nplhaib tuag me me, thiab lawv hnav ib leeg;lub kaum sab xis ntawm cov khoom sib kis tsis zoo, ua rau tsis sib xws ntawm cov khoom siv thiab hnav ib nrab;cov hlau poob rau hauv qhov tuag thiab hnav.Nyob rau hauv cov ntaub ntawv no, lub nplhaib tuag feem ntau hnav irregularly, feem ntau nyob rau hauv cov duab ntawm lub duav nruas nruas.
