Vim li cas cov khoom tiav ua tiav los ntawm Biomass Pellet Tshuab Rough?

Nyob rau hauv kev siv lub tshuab biomass pellet, qhov tuag compression piv yog hais txog ntau yam kev mob uas muaj kev cuam tshuam zoo rau kev siv cov pwm, xws li aperture, thickness, trumpet taper thiab expansion, pwm khoom thiab hardness. Feem ntau hais lus, qhov sib piv ntawm cov tshuab pellet tuag yog txiav txim siab raws li cov khoom siv raw, thiab cov pwm ntawm lub tshuab biomass pellet tseem ceeb heev rau kev molding ntawm cov khoom siv raw. Cov pwm yog tuab heev, cov khoom siv raw moulding lub sij hawm ntev, qhov particle ntom yog loj, thiab extrusion nyuaj. Cov pwm yog nyias thiab yooj yim tawg, particle ntom kuj me me, qhov kub ntawm extrusion yog tsawg, tab sis tus nqi sib sau yog tsawg los yog kev sib sau tsis zoo.
Roughness kuj yog ib qho tseem ceeb qhia rau kev ntsuas qhov zoo ntawm lub nplhaib tuag. Nyob rau hauv tib lub compression piv, qhov loj dua tus nqi roughness, qhov muaj zog ntawm kev tiv thaiv extrusion kev ua tau zoo ntawm cov ntoo nti pellets, thiab qhov nyuaj dua nws yog tawm. Ntau dhau roughness tseem yuav cuam tshuam rau qhov zoo ntawm cov khoom seem. Qhov tsim nyog roughness tus nqi yuav tsum nyob nruab nrab ntawm 0.8 thiab 16. Qhov kev tuag compression piv pelletizer yog txiav txim siab raws li cov khoom siv raw. Piv txwv li, compression piv ntawm poplar yog 1: 6, compression piv ntawm ntoo thuv yog 1: 7, compression ratio ntawm hardwood yog 1: 5, compression ratio ntawm ntoo chips yog 1: 5.5, thiab compression ratio ntawm pob kws. 1: 6,5. Los ntawm cov lej yooj yim no, peb tuaj yeem pom tias cov compression piv ntawm cov khoom raw sib txawv. Qhov nyuaj ntawm cov khoom siv raw, qhov tsawg dua qhov compression piv. Qhov ntau raw cov ntaub ntawv, qhov ntau dua qhov compression piv. Hauv lwm lo lus, qhov loj ntawm cov khoom siv raw, qhov yooj yim dua nws yog nias thiab tsim. Qhov loj ntawm cov khoom siv raw, cov fibers ntau dua, thiab qhov yooj yim dua nws yog tsim cov ntaub ntawv nrog ntau fibers. Yog li cia peb tham txog compression piv ntawm poplar ntoo ntawm 1: 6.

Tsis tas li ntawd, thaum lub sij hawm sib tsoo ntawm cov khoom siv, kev sib tsoo ntawm tag nrho cov hniav yog inevitable. Ntawm cov khoom sib tsoo, kev sib tsoo claws thiab hammers yog qhov tsis zoo ntawm cov sawdust grinder, thiab lawv kuj yog cov khoom tseem ceeb uas cuam tshuam rau kev sib tsoo zoo thiab kev tsim khoom. Kev sib tsoo claws thiab rauj yuav tsum tau hloov lub sijhawm tom qab hnav. Thaum hloov cov claws ntawm claw crusher, lub disc yuav tsum tau rub tawm ua ntej.
Hauv cov ntsiab lus, kev sib tsoo ntawm cov khoom sib txawv thaum lub sij hawm sib tsoo yog qhov sib txawv, uas yog ze rau lawv cov khoom. Tsis tas li ntawd, nws yuav tsum tau muab sau tseg tias nyob rau hauv cov txheej txheem ntawm kev xaiv thiab yuav khoom thiab pwm, tshwj xeeb yuav tsum tau them rau lawv cov thickness thiab roughness, uas yuav cuam tshuam rau molding zoo ntawm biomass pellets.
