Lub tshuab sawdust pellet hauv tsev tsis tso tawm pellets yog ib qho tseem ceeb tshaj plaws hauv biomass pellet ntau lawm. Nws tuaj yeem ua rau lub tshuab overload, ntau lawm nres, thiab cov khoom pov tseg.

 

Phau ntawv qhia no muab:

• Cov tsos mob ua tsis tiav
• Kev txheeb xyuas hauv paus (5 yam tseem ceeb)
• Kev daws teeb meem ceev ceev
• Kev tiv thaiv cov tswv yim kho

 

1. Cov tsos mob tseem ceeb ntawm Tsev siv pellet zeb ntoo pelletizer Tsis tso tawm

Table: Failure Symptoms Overview

Cov tsos mob	Kev piav qhia	Txaus ntshai
Tsis muaj pellet tso zis	Cov khoom nkag mus rau hauv chamber tab sis tsis muaj pellets tsim	Ua kom tiav kev tsim khoom nres
Lub cev muaj zog tshaj	Tam sim no nce, lub cev muaj zog ua kom nrov nrov	Motor burnout txaus ntshai
Khoom tsim	Chamber filling nrog raw khoom	Internal blockage & overheating
Tshuab tripping	Cov cuab yeej kaw cia li	Kev nyab xeeb

2. Qhov laj thawj tseem ceeb & kho sai

Cov lus: Ua rau thiab kev daws rau Tsis Muaj Pellet Production

Ua rau	Tej teeb meem	Kev daws
Moisture imbalance	Cov khoom qhuav dhau los yog ntub dhau	Tswj noo noo ntawm13%–15%
Tsis ncaj tuag compression ratio	Kev tiv thaiv ntau dhau	Match tuag rau raw khoom
Roller-die gap yuam kev	Tsis muaj zog extrusion	Kho qhov sib txawv rau0.1-0.3 hli
Tuag thaiv	Carbonized khoom clogging	Ntxuav los yog chav kho mob
Noj tsis ua hauj lwm	Tsis muaj lossis tsis sib npaug	Kho feeder & tiv thaiv bridging

3. Raw Material Moisture Issues (feem ntau yog vim li cas)

Table: Moisture cuam tshuam rau Pelletizing

Moisture Level	nyhuv	Kev tshwm sim
<10% (Too dry)	Tsawg kev sib txhuam & kev sib txuas	Tsis muaj pellet tsim
13% -15% (zoo tshaj)	Balanced plasticity	ruaj khov pellet ntau lawm
>18% (ntau dhau)	nplaum & txhaws	Tuag thaiv

 

Kev daws teeb meem

• Siv lub ntsuas dej noo kom tswj tau qhov tseeb
• High noo noo → siv lub tshuab ziab khaub ncaws
• Tsawg noo noo → txau dej + sib tov sib npaug

4. Biofuel Sawdust Pellet Tshuab pwm compression piv mismatch

Cov tsos mob

• Tsis muaj pellets tom qab hloov cov khoom siv raw
• Kev tuag tshiab ua rau muaj kev thaiv tam sim
• Lub cev muaj zog overload thaum pib

Pom zoo Compression Ratios

Hom khoom	Compression Ratio
Softwood (Poblar)	1:1.8 – 1:2.0
Hardwood (zeeg)	1:2.0 – 1:2.2

 

Kev daws teeb meem

• Xaiv tuag raws li hom khoom siv raw
• Khiav-nyob rau hauv tshiab tuag nrog roj + nplua sawdust rau2-3 teev

5. Tsis raug Cov Menyuam Gap hauv Hay Pellet Tshuab

Table: Gap Impact

Loj Loj	Teeb meem
>0.3mm ib	Tsis muaj extrusion, roller idling
0.1-0.3 hli	Kev ua haujlwm zoo tshaj plaws
<0.1 mm	Kev sib txhuam ntau dhau, kev pheej hmoo ntawm jamming

 

Kev daws teeb meem

• Kho siv lub ntsuas ntsuas ntsuas
• Recheck txhua txhua500 teev ua haujlwm

6. Hauv tsev ntoo pellet tshuab pwm clogging thiab khoom sintering

Cov tsos mob

• Tsis muaj cov zis tom qab rov pib dua
• Tuag qhov thaiv tag nrho
• Carbonized txheej hauv tuag

 

Ua rau

• Tsis muaj khoob khiav ua ntej kaw
• Cov khoom seem carbonized
• impurities (hlau, xuab zeb) thaiv qhov

 

Cov lus daws teeb meem

Txoj kev	Kev ua
Kho tshuab ntxuav	Siv lub qhov taub ntxuav rab koob
Thermal ntxuav	Thov80-100℃chav
Txoj kev tiv thaiv	Khiav roj + sawdust ua ntej kaw

7. Kev pub mis tsis ua haujlwm hauv Wood Chip Pellet txiag tshuab

Table: Pub Cov Teeb Meem & Txhim Kho

Teeb meem	Ua rau	Kev daws
Tsis pub noj	Ntsia hlau thaiv	Ntxuav feeder
Kev pub mis tsis sib npaug	Inverter tsis ua hauj lwm	Kho hluav taws xob system
Kev hla	Material arching nyob rau hauv hopper	Nruab vibrator

8. Kev daws teeb meem ceev ceev ua haujlwm

👉 Yog tias koj lub tshuab biomass sawdust pellet tsis tso tawm, ua raws li qhov kev txiav txim no:

• Tshawb xyuasraw khoom noo noo (13-15%)
• Tshawb xyuastuag thaiv
• KhoRoller-Die Gap (0.1-0.3 hli)
• Paub meejtuag compression piv piv cov khoom
• Tshawb xyuaspub system ua haujlwm

 

9. Cov lus qhia txog kev tiv thaiv

Table: Daim ntawv teev kev kho mob

Ua haujlwm	Ntau zaus
Kev ntsuas dej noo	Txhua batch
Roller gap check	Txhua 500 teev
Tuag tu	Txhua hnub
Kev saib xyuas tob	Txhua hli

10. Qhov tseem ceeb Takeaways

• Feem ntau yog vim li cas tsis muaj pellet tso tawm yogCov dej tsis raug (tsis yog 13-15%)
• Tuag blockage thiab compression piv mismatch yog covlub ntsiab mechanical ua
• Raws li cov menyuam-tuag qhov sib txawv (0.1-0.3 hli) yog qhov tseem ceeb rau extrusion
• Kev tiv thaiv kev tu thiab kho cov txheej txheem kaw kom raugzam 80% ntawm kev ua tsis tiav
