Nkhumba manyowa feteleza granulation zida
Zida zopangira manyowa a nkhumba zimagwiritsidwa ntchito potembenuza manyowa a nkhumba zofufuma kukhala feteleza wa granular kuti azigwira, kunyamula, ndikugwiritsa ntchito mosavuta.Zipangizozi zidapangidwa kuti zisinthe manyowa a nkhumba opangidwa ndi kompositi kukhala ma granules akulu akulu, omwe amatha kusinthidwa malinga ndi kukula kwake, mawonekedwe, ndi michere yomwe ikufunika.
Mitundu yayikulu ya zida zopangira manyowa a nkhumba ndi:
1.Disc granulator: Pazida zamtundu uwu, manyowa a nkhumba opangidwa ndi kompositi amadyetsedwa pa diski yozungulira, yomwe imakhala ndi kuthamanga kwambiri.Zinthuzo zimakakamizika kugudubuza ndikupanga ma pellets ang'onoang'ono chifukwa cha mphamvu ya centrifugal yopangidwa ndi diski yozungulira.Kenako ma pellets amawumitsidwa ndikuzizidwa kuti apange feteleza wa granular.
2.Drum granulator: Mu zipangizo zamtundu uwu, manyowa a nkhumba opangidwa ndi kompositi amadyetsedwa mu ng'oma yozungulira, yomwe imakhala ndi maulendo okwera ndege kapena paddles.Zinthuzo zimakwezedwa ndikugwetsedwa mkati mwa ng'oma, ndikupangitsa kuti ikhale ma granules.Kenako ma granules amaumitsa ndi kuziziritsidwa kuti apange feteleza wofanana.
3.Extrusion granulator: Mu zipangizo zamtundu uwu, manyowa a nkhumba opangidwa ndi kompositi amakakamizika kupyolera mu mbale yakufa pansi pa kupanikizika kwakukulu kuti apange pellets ya cylindrical kapena spherical.Mbale yakufa imatha kusinthidwa kuti ipange ma pellets amitundu yosiyanasiyana komanso mawonekedwe.
4.Rotary granulator: Mu mtundu uwu wa zipangizo, manyowa a nkhumba opangidwa ndi kompositi amadyetsedwa mu ng'oma yozungulira, yomwe imakhala ndi mavane kapena masamba.Zinthuzo zimakwezedwa ndikugwetsedwa mkati mwa ng'oma, ndikupangitsa kuti ikhale ma granules.Kenako ma granules amaumitsa ndi kuziziritsidwa kuti apange feteleza wofanana.
Kugwiritsa ntchito zida zopangira manyowa a nkhumba kungathandize kupanga feteleza wokulirapo, wapamwamba kwambiri yemwe ndi wosavuta kugwira, kusunga, ndikuyika.Zipangizozi zitha kusinthidwa malinga ndi zosowa zenizeni za opareshoni, kuphatikiza kukula, mawonekedwe, ndi michere ya ma granules.
