Biomass roj yog ib qho tshiab columnar ib puag ncig tiv thaiv lub zog tsim los ntawm biomass roj pellet machining, xws li straw, straw, nplej husk, peanut husk, corncob, camellia husk, cottonseed husk, thiab lwm yam. Lub cheeb ntawm biomass hais feem ntau yog 6 mus rau 12 mm. Cov nram qab no yog tsib yam laj thawj rau qhov txawv txav ntawm cov pellets hauv lub tshuab pellet.

1. Cov pellets yog nkhaus thiab qhia ntau qhov tawg ntawm ib sab

Qhov tshwm sim no feem ntau tshwm sim thaum cov roj particulate tawm ntawm qhov chaw annular. Thaum lub sij hawm tsim cov txheej txheem, thaum lub cutter nyob deb ntawm qhov chaw ntawm lub nplhaib tuag thiab ntug ua npub, cov pellets extruded los ntawm lub nplhaib tuag qhov ntawm lub tshuab biomass pellet yuav tawg los yog torn los ntawm lub cutter es tsis txhob ntawm ib txwm txiav. Cov roj khoov thiab lwm cov kab nrib pleb tshwm rau ntawm ib sab. Cov roj granular no tau yooj yim tawg thaum lub sijhawm thauj mus los thiab ntau cov hmoov tshwm.

2. Kab rov tav tawg nkag mus rau tag nrho cov khoom

Cov kab nrib pleb tshwm nyob rau hauv ntu ntu ntawm cov particle. Cov khoom siv fluffy muaj cov fibers ntawm qee qhov pore loj, yog li muaj ntau cov fibers muaj nyob rau hauv formulation, thiab thaum cov granules extruded, cov fibers tawg nyob rau hauv tus ntoo khaub lig-section ntawm nthuav granules.

3. Cov khoom ua rau cov kab nrib pleb ntev

Cov mis muaj fluffy thiab me ntsis elastic raw cov ntaub ntawv uas nqus thiab o tom qab quenching thiab tempering. Tom qab compression thiab granulation los ntawm ib tug annular tuag, longitudinal tawg yuav tshwm sim vim qhov kev txiav txim ntawm dej thiab elasticity ntawm raw khoom nws tus kheej.

4. Particles tsim radial tawg

Tsis zoo li lwm cov ntaub ntawv softer, nws yog ib qho nyuaj kom nqus tau cov dej noo thiab cua sov los ntawm cov chav vim tias cov pellets muaj cov khoom loj. Cov ntaub ntawv no zoo li muag muag. Cov khoom tuaj yeem ua rau tawg tawg vim qhov sib txawv ntawm softening thaum lub caij txias.

5. Qhov saum npoo ntawm biomass hais tsis tiaj tus

Irregularities nyob rau hauv particle nto tuaj yeem cuam tshuam qhov tsos. Cov hmoov siv rau granulation muaj cov ntaub ntawv loj granular uas tsis yog pulverized los yog semi-pulverized, thiab tsis txaus softened thaum tempering thiab tsis ua ke zoo nrog lwm cov ntaub ntawv raw thaum dhau qhov tuag qhov ntawm cov roj granulator, yog li ntawd, cov particle nto tsis tiaj tus.
