Vim li cas koj lub tiaj tus tuag Biofuel Sawdust Pellet Tshuab tsim Coarse Pellets?

May 14, 2026

Hauv kev lag luam roj biomass, "sov saum npoo" ntawm cov pellet yog qhov tseem ceeb ntawm nws qhov ntom thiab zoo. Antxhib kev ntxhib los mos-tus yam ntxwv los ntawm qhov chaw ntxhib, pom cov fibers, lossis matte tiav- feem ntau txhais tau hais tias lignin nyob rau hauv ntoo tsis tau ua kom zoo los yog lub tshuab siab tsis ruaj khov.

Feem ntau yog vim li cas rau coarse wood pellets yog:

Tsawg Moisture:Cov khoom nyoos qhuav dhau los "polish" tiv thaiv qhov tuag.
Oversized Particles:Sawdust daim loj dua 5 hli tsim "scaly" nto.
Hnav Pellet Tuag:Cov phab ntsa sab hauv ntawm qhov tuag qhov yog tsis du.
Tsawg Compression:Cov menyuam -rau- qhov sib txawv tuag yog qhov dav dhau, txo qhov fusion nto.

7 Ua rau Coarse Pellet Texture thiab Yuav Kho Li Cas

1. Optimize Sawdust Moisture (Lub Hom Phiaj: 10%–15%)

Moisture yog "lubricant" uas pab cov pellets swb los ntawm qhov tuag, tsim kom muaj qhov ci, du nto.

Qhov teeb meem:Yog sawdust yogqis dua 10% noo noo, kev sib txhuam yog siab dhau, thiab lignin yuav tsis yaj. Qhov no ua rau "hlawv" lossis ntxhib, ntawv xuab zeb-zoo li kev ntxhib los mos.
Qhov Kho:Hom phiaj rau12% noo noo. Yog tias cov khoom qhuav dhau lawm, siv lub tshuab misting hauv koj lub tshuab tov kom ntxiv dej maj mam ua ntej pelletizing.

2. Standardize Particle Loj (Lub Hom Phiaj: 3–5 mm)

Qhov teeb meem:Thaum koj muaj cov ntoo loj lossis cov fibers ntev, lawv tsis sib xyaw zoo. Cov khoom loj no lo tawm ntawm cov pellet, tsim kom muaj "plaub hau" los yog ntxhib tsos.
Qhov Kho:Xyuas kom kojrauj zebkev tshuaj ntsuam xyuas kom zoo. Tag nrho cov raw khoom yuav tsum tau crushed mus rau ib tug uniform3-5 mm-hlirau qhov smoothest tiav.

3. Hloov Hnav lossis khawbFlat tuag biomass roj Pellet ua tshuabTuag

Qhov teeb meem:Nyob rau tib lub sijhawm, sab hauv ntawm qhov tuag qhov yuav pitted los yog khawb. Cov imperfections no yog "mirrored" rau saum npoo ntawm pellet li nws yog extruded.
Qhov Kho:Tsis tu ncua ntxuav koj cov tuag nrogoily sawdust. Yog hais tias cov pellets tseem ntxhib txawm tias muaj dej noo, nws yog lub sij hawm los hloov covpellet zeb tuag.

4. Kho cov Roller - mus rau - Die Gap (0.1mm–0.3mm)

Qhov teeb meem:Yog tias qhov sib txawv dav dhau, cov khoom siv yog "squeezed" es tsis yog "fused." Qhov tsis muaj lub siab nruj no tiv thaiv cov pellet los ntawm kev tsim cov tawv tawv, du sab nrauv.
Qhov Kho:Tighten koj rollers mus rau qhov clearance ntawm0.1mm-0.3 hli. Cov rollers yuav tsum tsuas yog NW nyuam qhuav kov qhov tuag nto.

5. Stabilize pub ceev ntawmib tug ca tuag biomass pellet tshuab

Qhov teeb meem:Kev pub mis tsis tu ncua ua rau qhov kub hauv lub pelletizing chamber hloov pauv. Txij li thaum tshav kub yuav tsum tau yaj lignin rau ib tug du tiav, tsis ruaj khov noj ua rau inconsistent kev ntxhib los mos.
Qhov Kho:Siv ibtsis siv neeg ntsia hlau feeder nrog VFDkom tswj tau qhov ntws tsis tu ncua ntawm cov khoom mus rau hauv lub chamber.

6. Kho qhov Die Compression Ratio ntawm apav ca tuag biomass pellet ua tshuab

Qhov teeb meem:Siv cov ntoo softwood tuag (tsawg compression) rau hardwood (uas xav tau ntau lub siab) yuav ua rau ib tug ntxhib, matte tiav vim hais tias cov khoom tsis yog compacted txaus.
Qhov Kho:Xyuas kom kojtuag compression ratiophim koj hom raw khoom (piv txwv li, 1:5 rau hardwood, 1:6 rau softwood).

7. Clean Clogged los yog Carbonized Tuag Qhov nyob rau hauv Flat Die biomass sawdust pellet tshuab

Qhov teeb meem:Yog tias qee lub qhov raug thaiv ib nrab nrog carbonized biomass, cov pellets uas tawm los feem ntau raug yuam los ntawm qhov tsis sib xws, ua rau qhov ntxhib lossis "scaly" nto.
Qhov Kho:Ua ib hnub"oil flux"ua ntej kaw los tiv thaiv cov khoom los ntawm hardening thiab khawb qhov tuag qhov.

Ceev Diagnostic: Pellet Surface Teeb meem vs

Cov tsos mob	Qhov Tseem Ceeb	Kev Ua Tam Sim No
Rough, sandpaper -zoo li nto	Moisture tsawg dhau (<10%)	Ntxiv 1-2% dej rau tov
Pom tau ntoo fibers / "Hairy" pellets	Particle loj heev	Re- tsoo cov khoom rau 3-5mm
Pellet muaj khawb tob	Hnav / puas tuag qhov	Hloov cov pellet tuag
Matte, npub tiav (tsis ci)	Tsawg compression siab	Tighten rollers; Txheeb xyuas qhov ratio
Kev ntxhib los mos tsis sib xws hauv ib pawg	Kev pub mis tsis ruaj tsis khov	Siv VFD-tswj feeder

Vim li cas Smooth Pellets zoo dua rau koj txoj kev lag luam

Hauv kev lag luam kev lag luam, du, glossy pellets tsis yog rau qhov zoo nkaus li - lawv sawv cev zoo:

Cov plua plav qis:Smooth pellets muaj "tawv tawv" nyuaj thiab tsis tsim cov plua plav (nplua) thaum thauj.
Higher Bulk Density:Smooth pellets ntim ntau nruj, ua rau kev xa khoom zoo dua.
Cov neeg siv khoom ntseeg:Glossy pellets yog ib qho kev lag luam - tus qauv qhia ntawm siab - zoo, siab - BTU roj.

FAQ

Vim li cas kuv cov ntoo pellets ntxhib rau saum npoo?

Ib tug ntxhib nto yog feem ntau tshwm sim los ntawmqhuav raw khoom(hauv qab 10% noo noo) los yogoversized ntoo hais. Tsis muaj dej noo txaus, lub ntuj lignin hauv ntoo tsis yaj, tiv thaiv cov pellet los ntawm kev tsim kom zoo, polished tiav thaum nws dhau los ntawm kev tuag.

Kuv tuaj yeem ua rau kuv cov ntoo pellets zoo li du thiab ci?

Kom ua tiav "glossy" tiav: 1. Khaws12% noo noo, 2. Siv asiab compression tuag, thiab 3. Xyuas kom kojroller qhov sib txawvyog teem rau 0.1-0.3mm. Cov cua sov uas tsim los ntawm kev kub siab yuav yaj cov lignin, tsim cov yas zoo li txheej rau ntawm cov pellet nto.

Puas yog sawdust ya raws cuam tshuam pellet kev ntxhib los mos?

Yog, tseem ceeb heev. Yog tias cov sawdust ntub dhau, koj tuaj yeem tau txais "kua tawg." Yog tias nws qhuav dhau, cov pellet yuav ntxhib thiab "scaly." Qhov zoo tshaj plaws rau qhov chaw du yog10% mus rau 15%.

Vim li cas kuv cov pellets muaj cov fibers pom tawm?

Qhov no yog ib qho cim ntawmcrushing tsis txaus. Yog tias koj lub rauj zeb tsim cov khoom loj dua 5 hli, cov fibers no tsis tuaj yeem ua tiav rau hauv cov pellet core thiab yuav lo tawm, ua rau ntxhib, "hairy" zoo nkauj.

Puas tuaj yeem hnav tuag ua rau cov tawv pellet tiav?

kiag li. Sab hauv "polish" ntawm qhov tuag tshiab pab tsim cov pellet du nto. Raws li cov tuag hnav tawm, cov phab ntsa sab hauv ntawm lub qhov ua ntxhib los yog pitted, uas hloov cov ntxhib ntxhib ntxhib ncaj qha mus rau pellets.
