Vim li cas Ntoo Plua Plav Pellet Ua Tshuab Ua Cov Pellet Cracked?
Hom Pellet Cracks thiab lawv qhia dab tsi
Cracked pellets yog ib qho ntawm cov cim pom pom tias lub tshuab plua plav pellet tsis ua haujlwm raws li txoj cai. Kev tawg tuaj yeem muab faib ua peb hom. Cov kab nrib pleb ntev khiav raws qhov ntev ntawm cov pellet thiab feem ntau taw tes rau qhov teeb meem ya raws lossis qhov kub tsis zoo. Cov kab nrib pleb tawg hla cov pellet ntawm lub sijhawm tsis tu ncua thiab feem ntau txuas nrog cov khoom noj tsis tu ncua lossis qhov loj me me tsis sib xws. Kev tawg hnyav, qhov twg cov pellet crumbles sai tom qab tawm hauv qhov tuag, qhia txog kev sib xyaw ua ke ntawm cov teeb meem, feem ntau tsis tshua muaj ya raws ua ke nrog kev sib tw loj heev. Kev txheeb xyuas hom kev tawg zoo li cas yog thawj kauj ruam ntawm kev kho cov txheej txheem.
Cov ntsiab lus noo noo thiab nws cov nyhuv ntawm Pellet kev ncaj ncees
Cov dej noo yog qhov feem ntau ua rau tawg pellets. Thaum cov khoom qhuav dua li 12%, cov pellets ua nkig thiab qhov chaw tawg thaum lawv txias thiab poob qhov kawg ntawm lawv cov dej noo. Qhov zoo tshaj plaws rau cov plua plav ntoo feem ntau yog 13-15%, qhov twg lignin yog mos txaus los khi cov khoom tab sis tsis ntub dej uas ua rau hauv qhov tuag. Thaum cov dej noo nce siab tshaj 18%, qhov teeb meem rov tshwm sim: cov dej ntau dhau tig mus rau chav thiab tsim cov kab nrib pleb thaum lub pellet nthuav dav thiab cog lus. Kev ntsuas cov dej noo ntawm txhua batch ua ntej ntau lawm yog qhov pheej yig tshaj plaws los tiv thaiv cov kab mob sib kis.
Die Temperature, Roller Gap, thiab Main Ncej Ceev
Peb lub tshuab teeb tsa ua haujlwm ua ke los tsim lub suab pellet. Qhov kub ntawm qhov tuag yuav tsum nquag nyob rau hauv thaj tsam ntawm 80-100 degrees Celsius, uas yog siab txaus kom soften lub ntuj lignin nyob rau hauv ntoo. Qhov sib txawv ntawm cov menyuam yuav tsum tau teem caij ntawm 0.1-0.3 hli; Qhov sib txawv loj heev cia cov chais hla dhau ntawm cov khoom, thiab qhov sib txawv me me ua rau hnav ntau dhau thiab cov cua sov hauv zos. Lub ntsiab ncej ceev yog feem ntau 200-300 rpm, thiab khiav tawm sab nraud qhov kev hloov pauv ntev npaum li cas cov khoom nyob rau hauv qhov siab ntawm qhov tuag. Thaum tawg pellets tshwm sim, xyuas peb qhov chaw nyob rau hauv kev txiav txim ua ntej hloov cov khoom siv raw.
Compression Ratio thiab Particle Size Xaiv
Lub compression piv ntawm cov tuag yuav tsum sib phim cov khoom siv raw. Kev tuag nrog qhov sib piv compression uas tsawg dhau rau cov khoom ua rau muag muag, tsis tshua muaj - cov pellets ceev uas tawg yooj yim thaum tuav. Ib qho piv txwv uas siab dhau ua rau cov pellets ntom tab sis kuj ua rau muaj zog siv zog thiab tuaj yeem ua rau cov pellet nto tawg los ntawm kev siab dhau. Rau cov hmoov av ntoo, qhov ntev fiber ntau kuj tseem ceeb: cov khoom hauv 1-3 hli feem ntau tsim cov pellets ruaj khov tshaj plaws. Cov fibers ntev dua yuav rov qab los tom qab tawm hauv qhov tuag, uas qhib cov kab nrib pleb raws cov pellet nto.
Kev Kho Cov Cai Uas Tiv Thaiv Cov Pellet Cracked
Cov khoom hnav hloov pauv tus cwj pwm ntawm lub tshuab txawm tias qhov chaw zoo. Cov tuag thiab cov menyuam hnav thaum lub sijhawm ua haujlwm, thiab cov tuag hnav ua pellets nrog cov npoo ntxhib thiab tsis sib xws. Ib txoj kev npaj tu vaj tse tiv thaiv feem ntau cov teeb meem tawg ua ntej lawv tshwm sim. Tshawb xyuas cov dej noo ntawm cov khoom siv raw ua ntej txhua batch. Tshawb xyuas qhov tuag txhua lub lim tiam rau qhov thaiv qhov thiab qhov chaw hnav. Tshawb xyuas thiab kho qhov sib txawv ntawm cov menyuam txhua 500 teev ua haujlwm. Hloov cov tuag, rollers, thiab lwm yam hnav txhua txhua 500-800 teev nyob ntawm seb qhov abrasiveness ntawm cov khoom. Ua kom lub tshuab nyob rau hauv tus mob no stabilizes pellet zoo thiab txo qhov sib faib ntawm cov pellets tawg los yog tawg.
Cov lus nug nquag
Dab tsi yog qhov dej noo zoo tshaj plaws rau cov hmoov av pelletizing?
Qhov zoo tshaj noo noo ntau yog 13-15%. Hauv qab 12% cov pellets ua nkig thiab tawg, thiab siab dua 18% cov ntaub ntawv hauv qhov tuag thiab ua rau tawg tawg.
Vim li cas kuv cov pellets tawg ob peb feeb tom qab tawm hauv qhov tuag?
Qhov no feem ntau yog teeb meem dej noo. Cov pellets ua los ntawm cov khoom siv drier dua 12% poob qhov seem ntawm cov dej noo sai sai tom qab tawm hauv qhov tuag thiab tawg raws li qhov chaw cog lus.
Dab tsi tuag qhov kub yog pom zoo rau cov ntoo pellet ntau lawm?
Rau feem ntau cov khoom siv plua plav, qhov kub tuag yuav tsum nyob rau hauv thaj tsam ntawm 80-100 degrees Celsius kom lub ntuj lignin softens thiab khi cov khoom ua ke.
Dab tsi yog qhov tseeb ntawm cov menyuam sib txawv ntawm lub tshuab pellet?
Qhov sib txawv ntawm cov menyuam yuav tsum tau teem caij ntawm 0.1-0.3 hli. Qhov sib txawv uas loj dhau ua rau cov chais plam, thiab qhov sib txawv me dhau ua rau hnav thiab kub dhau.
Ntev npaum li cas yuav tsum hnav qhov chaw hloov?
Cov neeg tuag thiab cov menyuam yaus feem ntau hloov pauv txhua 500-800 teev ua haujlwm, nyob ntawm seb qhov abrasiveness ntawm cov khoom siv raw, thiab qhov sib txawv ntawm cov menyuam yuav tsum tau kuaj xyuas txhua 500 teev.
Cov compression piv ntawm cov tuag puas ua rau tawg pellets?
Yog lawm. Qhov sib piv compression uas tsis sib xws rau cov khoom siv raw ua rau cov mos mos tsawg- ntom ntom pellets los yog tshaj - compressed pellets nrog tawg qhov chaw, yog li cov tuag yuav tsum tau sib phim rau hom fiber ntau thiab noo noo ntawm cov khoom.
