Wooddust Pellet Ua Tshuab Ua Txhaum Pellet: Ua thiab Kev daws

May 14, 2026

Cracked los yog brittle pellets yog ib qho teeb meem tseem ceeb hauv kev lag luam biomass. Lawv ua rau muaj qhov "nplua nuj" (plua plav) piv, tsis tshua muaj kev sib txuas, thiab cov neeg siv khoom tsis txaus siab. Thaum aNtiv nplhaib tuag Wood Chip Pellet txiag tshuabtsim cov pellets tawg, nws feem ntau txhais tau hais tias muaj qhov tsis sib xws ntawm covraw khoom mobthiab covmechanical nqis.

Txhawm rau kom ceev cov pellets los ntawm kev tawg, tsom mus rau 4 tus ncej:

Moisture Control:Lub hom phiaj ntawm 10% -15%.
Compression siab:Kho cov menyuam - mus rau - tuag qhov sib txawv (0.1mm–0.3mm).
Particle Loj:Xyuas kom sawdust yog crushed mus rau 3-5mm.
Txheej txheem cua txias:Tsis txhob "thermal shock" nrog maj mam txias.

7 Qhov Tseem Ceeb Ntawm Cov Ntoo Ntoo Pellet

1. Cov khoom siv raw tsis tsim nyog

Moisture yog "binder" uas tso cai rau lignin yaj thiab fuse ntoo fibers.

Qhov teeb meem:Yog sawdustqhuav dhau (<10%), cov fibers yuav tsis khi, ua rau cov kab nrib pleb ntev. Yogtoo wet (>15%), sab hauv chav nthuav dav raws li cov pellet tawm ntawm qhov tuag, "tawg" cov qauv ntawm sab hauv tawm.
Qhov Kho:Siv lub ntsuas dej noo kom ruaj khov12% noo noorau hardwood thiab me ntsis siab dua rau softwood.

2. Tsis txaus Compression Siab nyob rau hauv lub nplhaib tuag ntoo pelletize tshuab

Qhov teeb meem:Yog tias cov chais nyob deb dhau ntawm qhov tuag, cov khoom siv tsis tau nruj nruj txaus los tsim cov tub ntxhais, ua rau kab rov tav nto tawg.
Qhov Kho:Kho covroller-to- tuag gapmus raws nraim0.1mm-0.3 hli.

3. Ceev ceev (Thermal Shock)

Qhov teeb meem:Freshly extruded pellets yog kub heev (70℃-90 degree). Yog hais tias lawv raug rau siab tshaj - cua txias tam sim ntawd, sab nrauv shrinks sai dua cov tub ntxhais, ua rau kev sib cais.
Qhov Kho:Siv acounterflow txiaskom txo qhov kub thiab txias maj mam dhau ob peb feeb.

4. Cov khoom siv raw khoom ntau dhau

Qhov teeb meem:Ntoo chips loj dua 5 hli tsim "cov ntsiab lus tsis muaj zog" hauv cov pellet. Cov khoom loj no tsis khi zoo nrog cov plua plav zoo, ua rau cov pob txha tawg.
Qhov Kho:Xyuas kom kojrauj zebscreen yog qhov loj me los tsim3-5mm particle loj.

5. Hnav los yog ib nrab thaiv Pellet Tuag

Qhov teeb meem:Ib tug hnav tuag poob nws "compression ratio," txhais tau hais tias nws tsis siv lub zog raug. Thaiv qhov ua rau qhov tsis sib xws ntawm lub ntsej muag tuag.
Qhov Kho:Ua ib hnub"oil flux"nrog oily sawdust thiab hloov cov tuag txhua500-1,000 teevnyob ntawm cov khoom hardness.

6. Kev pub mis tsis ruaj khovnyob rau hauv ib lub nplhaib tuag sawdust pellet zeb

Qhov teeb meem:Surges nyob rau hauv lub feeding system ua rau lub siab hloov pauv. Tsawg-siab surges tsim xoob, tawg pellets.
Qhov Kho:Implement ibtsis siv neeg ntsia hlau feedernrog rau VFD (Variable Frequency Drive) kom ntws mus tas li.

7. Incorrect Die Compression Ratio nyob rau hauv lub nplhaib tuag Biomass Pellet Tshuab

Qhov teeb meem:Siv lub tshuab tuag tsim rau softwood los ua hardwood. Hardwood muaj kev tiv thaiv ntau dua; yog tias qhov compression siab dhau lawm, lub pellet dhau los ua dhau - ntxhov siab thiab tawg thaum tawm.
Qhov Kho:Tham nrog koj cov chaw tsim khoom kom phim covtuag compression ratiorau koj hom biomass tshwj xeeb.

FAQ

Vim li cas kuv cov ntoo pellets muaj cov kab nrib pleb ntawm qhov chaw?

Cov kab nrib pleb feem ntau yog ib qho cim ntawmnoo noo imbalancelos yogtsawg compression siab. Yog hais tias cov khoom siv raw yog me ntsis ntub dej, chav khiav tawm ntawm cov pellet thaum nws tawm hauv qhov tuag, tsim "tej" lossis pob txha tawg. Tightening kojroller-to- tuag gapfeem ntau pab daws qhov no.

Vim li cas kuv cov pellets tawg tom qab lawv hla lub qhov txias?

Qhov no yog tshwm sim los ntawmthermal shock. Yog tias cov pellets kub txias txias heev, qhov kev ntxhov siab sab hauv ua rau lawv sib cais. Txhawm rau kho qhov no, txo cov kiv cua ceev ntawm koj lub tshuab txias lossis xyuas kom koj siv acounterflow txias systemuas qhia txog huab cua maj mam.

Dab tsi yog qhov dej noo zoo tshaj plaws los tiv thaiv pellet tawg?

Rau feem ntau ntoo sawdust, qhov "qab zib" yog12% noo noo. Txhua yam hauv qab 10% yuav ua rau cov pellets nkig thiab plua plav, thaum txhua yam saum toj no 15% yuav ua rau lawv mos thiab yooj yim rau hauv chav tawg.

Cov sawdust loj tuaj yeem ua rau pellets tawg yooj yim?

Yog lawm. Cov khoom loj (siab dua 5 hli) tsis fuse zoo nrog cov khoom zoo nyob ib puag ncig. Lawv ua raws li "cov kab txhaum" hauv cov pellet. Rau siab tshaj plaws durability, tag nrho cov raw khoom yuav tsum tau crushed mus rau ib tug3-5mm uniform loj.

Yuav ua li cas kuv thiaj paub yog kuvNtoo Chip Pellet Ua Tshuabtuag dhau lawm os?

Yog tias koj pom ib qho kev nce ntxiv hauvnplua (dust)thiab cov pellets tawg txawm tias muaj qhov tseeb ntawm cov dej noo thiab cov menyuam sib txawv, koj qhov kev tuag qhov sib piv nrog cov compression yuav raug txo los ntawm kev hnav. Tshawb xyuas qhov "tswb-qhov ncauj" nkag ntawm lub qhov tuag kom pom tias yaig.
