Ob Chav Hniav Rau Cov Menyuam Plhaub
Lub plhaub menyuam ntawm lub tshuab pellet yog ib qho khoom siv tseem ceeb ntawm lub tshuab pelletizer, uas kuj yooj yim hnav ua lub nplhaib tuag. Nws ua haujlwm feem ntau nrog lub nplhaib tuag thiab lub plhaub tiaj tiaj los txiav, sib tsoo, teeb tsa, thiab nias cov khoom siv raw kom ua tiav pelletizing. Lub plhaub menyuam yog siv dav rau kev ua cov tsiaj pub pellets, biomass roj pellets, thiab lwm yam.
Hauv cov txheej txheem granulator, txhawm rau kom ntseeg tau tias cov khoom siv raw tuaj yeem raug nias rau hauv qhov tuag, yuav tsum muaj qee qhov kev sib txhuam ntawm lub plhaub roller thiab cov khoom siv, yog li thaum ua lub plhaub roller, nws yuav raug tsim nrog ntau hom ntawm cov nplaim ntxhib kom tiv thaiv lub roller los ntawm kev plam. Muaj peb hom nplaim uas siv dav tshaj plaws: hom dimpled, hom qhib-kawg, thiab hom kaw-kawg.
Lub plhaub menyuam dimpled
Qhov saum npoo ntawm lub plhaub dov uas muaj qhov me me zoo li lub honeycomb uas muaj qhov. Thaum siv, qhov hauv qhov puv nrog cov khoom siv, ua rau qhov sib txhuam ntawm qhov chaw sib txhuam me me, cov khoom siv tsis yooj yim swb mus rau sab, qhov hnav ntawm lub nplhaib tuag ntawm lub tshuab granulator yog sib xws dua, thiab qhov ntev ntawm cov khoom me me tau txais yog sib xws dua, tab sis qhov kev ua tau zoo ntawm cov khoom dov yog qhov phem dua me ntsis, tej zaum yuav muaj kev cuam tshuam rau qhov tsim tawm ntawm lub tshuab granulator, hauv kev tsim khoom tiag tiag tsis tshua muaj ntau npaum li hom qhib thiab kaw.
Qhib-kawg menyuam plhaub
Nws muaj peev xwm tiv thaiv kev plam thiab cov khoom siv dov zoo. Txawm li cas los xij, thaum lub sijhawm tsim khoom, cov khoom siv swb rau hauv qhov hniav, uas yuav ua rau muaj teeb meem ntawm cov khoom siv swb mus rau ib sab, ua rau muaj qhov sib txawv ntawm kev hnav ntawm lub plhaub menyuam thiab lub nplhaib tuag. Feem ntau, qhov hnav yog qhov hnyav ntawm ob qhov kawg ntawm lub plhaub menyuam thiab lub nplhaib tuag, uas yuav ua rau muaj teeb meem ntawm kev tso tawm cov khoom ntawm ob qhov kawg ntawm lub nplhaib tuag ntev, yog li cov pellets ua luv dua li qhov nruab nrab ntawm lub nplhaib tuag.
Kaw-kawg menyuam plhaub
Ob sab kawg ntawm hom plhaub menyuam no yog tsim los ua hom kaw (ib hom hniav groove nrog cov npoo kaw). Vim yog cov npoo kaw ntawm ob sab ntawm qhov groove, cov khoom siv raw tsis yooj yim swb mus rau ob sab hauv qab extrusion, tshwj xeeb tshaj yog thaum siv rau hauv extrusion ntawm cov ntaub ntawv dej uas muaj feem ntau swb. Qhov no txo qhov slippage no thiab ua rau muaj kev faib tawm ntawm cov khoom siv, ntau dua kev hnav ntawm lub plhaub menyuam thiab lub nplhaib tuag, thiab yog li ntawd ntau dua qhov ntev ntawm cov pellets.
