Kev Taw Qhia Txog Cov Khoom Siv Particle/Pellet Uas Tsis Zoo Li Qub thiab Kev Txhim Kho (Buhler Fumsun CPM pellet mill)

1. Cov khoom siv pellet yog khoov thiab muaj ntau qhov tawg ntawm ib sab
Feem ntau qhov xwm txheej no tshwm sim thaum cov khoom me me tawm ntawm lub nplhaib tuag. Thaum qhov chaw txiav raug kho kom deb ntawm qhov chaw ntawm lub nplhaib tuag thiab cov hniav yog blunt, cov khoom me me raug tsoo lossis rhuav los ntawm lub cuab yeej txiav thaum nias tawm ntawm lub qhov tuag, es tsis yog raug txiav tawm. Lub sijhawm no, qee cov khoom me me khoov rau ib sab thiab sab tod muaj ntau qhov tawg.

Cov txheej txheem txhim kho:
• Ua kom lub zog nias ntawm lub nplhaib tuag ntawm qhov pub, uas yog, ua kom qhov sib piv ntawm lub nplhaib tuag nce ntxiv, yog li ua rau qhov ceev thiab qhov nyuaj ntawm cov khoom siv pellet nce ntxiv;
• Muab cov khoom noj zom kom me me. Yog tias ntxiv cov kua txiv hmab txiv ntoo los yog cov rog, qhov sib npaug ntawm cov kua txiv hmab txiv ntoo los yog cov rog yuav tsum tau txhim kho thiab qhov ntau ntxiv yuav tsum tau tswj kom ua rau cov khoom pellet compact thiab tiv thaiv cov khoom noj kom tsis txhob mos;
•Kho qhov nrug ntawm cov hniav txiav thiab qhov chaw ntawm lub nplhaib tuag lossis hloov nws nrog cov hniav txiav ntse dua;
•Txais yuav cov khoom siv ntxiv rau cov nplaum kom txhim kho lub zog sib txuas ntawm cov khoom me me.

2. Cov kab nrib pleb kab rov tav hla tag nrho cov khoom me me
Zoo ib yam li qhov xwm txheej hauv qhov xwm txheej 1, cov kab nrib pleb tshwm sim ntawm qhov seem ntawm cov khoom me me, tab sis cov khoom me me tsis khoov. Qhov xwm txheej no yuav tshwm sim thaum pelletizing fluffy pub uas muaj ntau cov fiber. Vim muaj cov fibers ntev dua li qhov loj ntawm qhov pore, thaum cov khoom me me raug extruded, qhov nthuav dav ntawm cov fibers ua rau muaj cov kab nrib pleb transverse hauv qhov seem ntawm cov khoom me me, ua rau muaj cov tawv ntoo fir zoo li pub.

Cov hau kev los txhim kho:
• Ua kom lub zog nias ntawm lub nplhaib tuag ntawm qhov pub, uas yog, ua kom qhov piv ntawm kev nias ntawm lub nplhaib tuag nce ntxiv;
• Tswj qhov zoo ntawm cov fiber crushing, xyuas kom meej tias qhov ntev tshaj plaws tsis pub tshaj ib feem peb ntawm qhov loj me ntawm cov khoom me me;
• Ua kom muaj ntau ntxiv kom txo qhov ceev ntawm kev pub hla lub qhov tuag thiab ua kom compactness;
• Siv cov tshuaj conditioners ntau txheej los yog cov kettle kom ntev lub sijhawm tempering;
•Thaum cov hmoov av noo ntau dhau los yog muaj urea, nws kuj ua tau kom zoo li cov tawv ntoo fir. Yuav tsum tswj cov av noo thiab cov urea uas ntxiv rau.

3. Cov kab nrib pleb ntsug tshwm sim hauv cov khoom siv pellet
Cov mis pub mis muaj cov khoom siv fluffy thiab me ntsis elastic, uas yuav nqus dej thiab nthuav dav thaum kho los ntawm cov tshuaj conditioner. Tom qab raug nias thiab granulated los ntawm lub nplhaib tuag, nws yuav dhia sib nrug vim yog cov nyhuv ntawm dej thiab elasticity ntawm cov khoom siv raw nws tus kheej, ua rau muaj cov kab nrib pleb ntsug.

Cov kev txhim kho yog:
• Hloov cov mis, tab sis ua li ntawd yuav txo tau tus nqi ntawm cov khoom siv raw;
• Siv cov pa qhuav uas ntub heev;
•Txo qhov muaj peev xwm tsim khoom lossis nce qhov ntev ntawm lub qhov tuag kom ua kom lub sijhawm khaws cia ntawm cov khoom noj hauv lub qhov tuag ntev tshaj plaws;
•Ntxiv cov nplaum kuj tseem tuaj yeem pab txo qhov tshwm sim ntawm cov kab nrib pleb ntsug.
 
4. Kev tawg ntawm cov khoom siv pellet los ntawm ib qho chaw
Qhov tsos no qhia tau hais tias cov khoom siv pellet muaj cov khoom siv raw loj pellet, uas nyuaj rau nqus cov dej noo thiab cua sov hauv cov pa dej thaum lub sijhawm quenching thiab tempering, thiab tsis yooj yim mos li lwm cov khoom siv raw zoo. Txawm li cas los xij, thaum lub sijhawm txias, cov qib mos sib txawv ua rau muaj qhov sib txawv ntawm kev ntsws, ua rau muaj cov kab nrib pleb radial thiab nce ntxiv ntawm kev sib xyaw.
 
Cov kev txhim kho yog:
Tswj thiab txhim kho qhov zoo thiab sib xws ntawm cov ntaub ntawv raw, yog li txhua yam ntaub ntawv raw yuav tsum tau ua kom mos thiab sib xws thaum lub sijhawm tempering.

5. Qhov saum npoo ntawm cov khoom siv pellet tsis sib npaug
Qhov xwm txheej saum toj no yog tias cov hmoov muaj cov khoom siv loj loj, uas tsis tuaj yeem ua kom mos tag nrho thaum lub sijhawm tempering. Thaum hla lub qhov tuag ntawm lub tshuab granulator, nws tsis tuaj yeem sib xyaw zoo nrog lwm cov khoom siv raw, ua rau cov khoom me me zoo li tsis sib xws. Lwm qhov ua tau yog tias cov khoom siv quenched thiab tempered raw sib xyaw nrog cov pa npuas, uas tsim cov pa npuas thaum lub sijhawm nias cov khoom noj rau hauv cov khoom me me. Thaum lub sijhawm thaum cov khoom me me raug nias tawm ntawm lub nplhaib tuag, kev hloov pauv ntawm lub siab ua rau cov npuas tawg thiab ua rau tsis sib xws ntawm qhov chaw ntawm cov khoom me me. Txhua yam khoom noj uas muaj fiber yuav ntsib qhov xwm txheej no.

Cov txheej txheem txhim kho:
Tswj kom zoo qhov zoo ntawm cov hmoov pub, kom txhua yam khoom siv raw tuaj yeem mos tag nrho thaum lub sijhawm kho; Rau cov khoom siv raw uas muaj ntau cov fiber, vim lawv yooj yim rau cov npuas dej, tsis txhob ntxiv ntau cov pa rau cov mis no.

6. Cov khoom siv pellet zoo li hwj txwv
Yog tias ntxiv cov pa ntau dhau, cov pa ntau dhau yuav khaws cia rau hauv cov fibers lossis hmoov. Thaum cov khoom me me raug extruded los ntawm lub nplhaib tuag, qhov kev hloov pauv sai ntawm lub siab yuav ua rau cov khoom me me tawg thiab tawm ntawm qhov chaw ntawm cov protein lossis cov khoom me me, tsim cov plaub hau prickly. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hmoov txhuv nplej siab thiab cov khoom noj muaj fiber ntau, qhov ntau cov pa siv, qhov teeb meem loj dua.

Txoj kev txhim kho yog nyob rau hauv kev ua kom zoo.
•Cov khoom noj uas muaj hmoov txhuv nplej siab thiab cov fiber ntau yuav tsum siv cov pa dej qis (0.1-0.2Mpa) kom tso dej thiab cua sov tawm hauv cov pa dej kom nqus tau cov khoom noj.
• Yog tias lub zog ntawm cov pa dej siab dhau los yog cov kav dej hauv qab lub qhov txo qhov siab luv dhau ntawm lub qhov tswj, uas feem ntau yuav tsum ntau dua 4.5m, cov pa dej yuav tsis tso nws cov dej noo thiab cua sov zoo heev. Yog li ntawd, qee cov pa dej khaws cia rau hauv cov khoom noj khoom haus tom qab txias, uas tuaj yeem ua rau muaj qhov cuam tshuam zoo li cov khoom me me uas tau hais los saum toj no thaum lub sijhawm granulation. Hauv ntej, yuav tsum tau them sai sai rau kev tswj qhov siab ntawm cov pa dej thiab qhov chaw teeb tsa ntawm lub qhov txo qhov siab yuav tsum raug.

7. Cov khoom me me lossis cov khoom me me uas muaj xim tsis sib xws ntawm cov tib neeg, feem ntau hu ua "cov ntaub ntawv paj"
Nws yog ib qho tshwm sim hauv kev tsim cov khoom noj hauv dej, feem ntau yog cov xim ntawm cov khoom me me uas raug rho tawm ntawm lub nplhaib tuag ua tsaus dua lossis sib dua li lwm cov khoom me me, lossis cov xim ntawm cov khoom me me tsis sib xws, yog li cuam tshuam rau qhov zoo ntawm tag nrho cov khoom noj.
• Cov khoom siv raw rau cov khoom noj hauv dej muaj ntau yam sib xyaw ua ke, nrog ntau hom khoom siv raw, thiab qee cov khoom xyaw raug ntxiv rau hauv qhov me me, ua rau muaj kev sib xyaw tsis zoo;
• Cov dej noo tsis sib xws ntawm cov khoom siv raw siv rau kev ua granulation lossis kev sib tov tsis sib xws thaum ntxiv dej rau hauv lub tshuab sib tov;
• Cov khoom siv rov ua dua nrog kev ua granulation rov ua dua;
•Qhov tiav ntawm phab ntsa sab hauv ntawm lub nplhaib tuag qhov tsis sib xws;
• Kev hnav ntau dhau ntawm lub nplhaib tuag lossis lub log siab, kev tso tawm tsis sib xws ntawm cov qhov me me.
