Yuav ua li cas los daws cov roj pellet zeb tsis ua hauj lwm?

pellet qhov cub pellet tshuab tsim hluav taws xob tawg los ntawm qhov chaw taw tes thaum lub sij hawm tsim cov biomass pellets. Qhov laj thawj tseem ceeb rau qhov xwm txheej no yog tias cov roj biomass tsim los ntawm cov chaw tsim khoom pellet muaj cov roj biomass ntau dua. Cov ntaub ntawv raw nrog tib qib ntawm fiber ntau yog extruded thiab fused nrog ib leeg thaum lub sij hawm granulation, ua rau muaj cov fibers loj, uas cuam tshuam rau kev sib cuam tshuam ntawm fibers. Nws tsis yooj yim rau soften li lwm cov ntaub ntawv zoo, tab sis thaum txias, vim qhov sib txawv ntawm cov softening, tus nqi ntawm shrinkage kuj txawv, ua rau radial tawg. Txoj kev txhim kho yog kom tswj tau qhov tuab thiab sib xws ntawm cov hmoov roj raw cov ntaub ntawv, thiab ntxiv biomass raw cov ntaub ntawv nrog cov sieve loj loj los ntawm cov hmoov sieving yooj yim ua ntej granulation.

me me biomass pellet txiag Qhov saum npoo ntawm cov khoom pellet tsis sib xws. Qhov teeb meem no yog tias cov hmoov granulated muaj uncrushed los yog semi-crushed loj particle raw khoom. Vim hais tias cov khoom yog qhov nyuaj thiab loj heev, lawv tsis tuaj yeem ua ke nrog lwm cov ntaub ntawv raw los ntawm lub tshuab pellet tuag qhov ntawm lub tshuab pellet chaw tsim khoom, ua rau cov khoom tsis sib xws. Txoj kev txhim kho yog los tswj cov thickness ntawm cov hmoov raw khoom kom zoo. me me pellet zeb tshuab Cov xim ntawm ib tus neeg los yog cov khoom ntawm cov tib neeg tsis sib xws, feem ntau hu ua paj khoom. Qhov xwm txheej no tsis tshua muaj thiab feem ntau tshwm sim nws tus kheej nyob rau hauv qhov tseeb tias cov xim ntawm ib tug neeg hais extruded nyob rau hauv ib tug annular duab yog ib tsos tsaus tsawv los yog sib dua li cov xim ntawm lwm yam ib txwm hais, los yog cov xim ntawm ib tug neeg hais yog xim nto yog inconsistent, uas muaj feem xyuam rau. tag nrho cov tsos zoo ntawm cov roj. Cov laj thawj tseem ceeb ntawm qhov tshwm sim no yog raws li hauv qab no: Muaj cov khoom xa rov qab uas tau rov ua dua tshiab hauv granulation rau hauv. Cov khoom siv granulated tuaj yeem dhau los ua cov khoom tiav tom qab txias thiab tshuaj ntsuam. Cov tshuaj ntsuam xyuas cov hmoov zoo thiab cov khoom me me feem ntau nkag mus rau cov txheej txheem rau rov ua cov granulation, feem ntau yog mus rau hauv lub tov khoom thiab cov granule rau hauv yuav tsum tau ua. Txij li cov khoom siv rov ua dua tshiab yog cov khoom siv rov ua dua tshiab, nws tsis sib npaug nrog lwm cov khoom siv raw lossis sib xyaw nrog cov khoom siv rov ua dua tshiab, qee zaum ua rau khib nyiab. Lub puab phab ntsa ntawm lub annular aperture muaj inconsistent roughness. Vim qhov tsis sib haum xeeb ntawm qhov tuag qhov ntawm cov tshuab pellet manufacturers, qhov kev tiv thaiv thiab extrusion siab tau ntsib los ntawm cov khoom thaum lub sij hawm extrusion txawv, thiab cov xim hloov kuj tsis sib xws. Tsis tas li ntawd, muaj burrs rau ntawm phab ntsa ntawm lub qhov annular, uas ua rau lub ntsej muag puas thaum cov khoom extruded, thiab cov xim ntawm cov khoom sib txawv. Rau cov laj thawj saum toj no rau kev tsim paj, txoj kev txhim kho yog qhov tseeb heev. Tswj cov khoom siv rov ua dua tshiab. Rau cov khoom uas nquag ua paj, cov khoom siv rov ua dua tshiab yuav tsum tau tov nrog cov khoom siv raw thiab ces crushed. Cov ntoo roj pellet ua tshuab txais qhov zoo Guaranteed nplhaib pwm, tswj qhov smoothness ntawm pwm qhov, thiab xuab zeb lub pwm qhov ua ntej siv yog tias tsim nyog.
