Chipolopolo Chozungulira Mano Awiri
Chipolopolo cha pellet mill ndi chinthu chofunikira kwambiri pa pelletizer, chomwe chimakhala chosavuta kuvala pamene mphete ikufa. Chimagwira ntchito makamaka ndi mphete yofewa komanso yosalala yodulira, kukanda, kuyika, ndikufinya zipangizo zopangira kuti zifewetsedwe. Zipolopolo za roller zimagwiritsidwa ntchito kwambiri pokonza ma pellets a chakudya cha ziweto, ma pellets amafuta a biomass, ndi zina zotero.
Mu ndondomeko ya granulator, kuti zitsimikizire kuti zopangira zitha kukanikiza mu dzenje la die, payenera kukhala kukangana pakati pa chipolopolo cha roller ndi zinthuzo, kotero popanga chipolopolo cha roller, chidzapangidwa ndi mitundu yosiyanasiyana ya malo okhwima kuti roller isaterereke. Pali mitundu itatu ya malo omwe amagwiritsidwa ntchito kwambiri: mtundu wa dimpled, mtundu wa open-end, ndi mtundu wa closed-end.
Chipolopolo Chozungulira Chokhala ndi Dimpled
Pamwamba pa chipolopolo chozungulira chokhala ndi ma dimpled chimakhala ngati uchi wokhala ndi mabowo. Pakugwiritsa ntchito, bowolo limadzazidwa ndi zinthu, kupanga friction surface friction coefficient ndi yaying'ono, zinthuzo sizimavuta kutsetsereka m'mbali, ring die ya granulator imakhala yofanana, ndipo kutalika kwa tinthu tating'onoting'ono tomwe tapezeka kumakhala kofanana, koma magwiridwe antchito a roll ndi oyipa pang'ono, pakhoza kukhala kukhudza kukolola kwa granulator, popanga zenizeni sikofala ngati mitundu yotseguka ndi yotsekedwa.
Chipolopolo Chozungulira Chotseguka
Ili ndi mphamvu yolimba yoletsa kutsetsereka komanso magwiridwe antchito abwino a zinthu zozungulira. Komabe, popanga, zinthuzo zimatsetsereka mu dzenje la dzino, zomwe zingayambitse vuto la zinthu zotsetsereka kumbali imodzi, zomwe zimapangitsa kuti chipolopolo cha roller ndi mphete zisinthe. Nthawi zambiri, kuwonongeka kumakhala kwakukulu kumapeto awiri a chipolopolo cha roller ndi mphete, zomwe zimapangitsa kuti zinthu zikhale zovuta kutulutsa kumapeto awiri a mphete kwa nthawi yayitali, kotero ma pellet opangidwa ndi afupiafupi kuposa gawo lapakati la mphete.
Chipolopolo Chozungulira Chotsekedwa
Malekezero awiri a chipolopolo cha mtundu uwu cha roller adapangidwa kuti akhale otsekedwa (mtundu wa groove wokhala ndi m'mbali zotsekedwa). Chifukwa cha m'mbali zonse ziwiri za groove, zinthu zopangira sizimatsetsereka mosavuta mbali zonse ziwiri pansi pa extrusion, makamaka zikagwiritsidwa ntchito potulutsa zinthu zam'madzi zomwe zimakhala zosavuta kutsetsereka. Izi zimachepetsa kutsetsereka kumeneku ndipo zimapangitsa kuti zinthuzo zigawike mofanana, kutayika kwa chipolopolo cha roller ndi ring die, motero kutalika kwa ma pellets kumakhala kofanana.
