Amafomu wezinto eziyinhloko akha i-biomass particle molding ayizinhlayiya ezinobukhulu obuhlukahlukene bezinhlayiyana, futhi izici zokugcwalisa, izici zokugeleza nezici zokucindezela zezinhlayiya ngesikhathi senqubo yokucindezela zinethonya elikhulu ekubunjweni kokucindezela kwe-biomass.

I-biomass pellet compression molding ihlukaniswe izigaba ezimbili.

Esigabeni sokuqala, esigabeni sokuqala sokucindezelwa, ingcindezi ephansi idluliselwa ku-biomass impahla eluhlaza, ukuze ukwakheka kokuhlelwa kwezinto ezingavuthiwe okugcwele kuqale ukushintsha, futhi isilinganiso sangaphakathi esingenalutho se-biomass sinciphe.

Esigabeni sesibili, lapho ingcindezi ikhula kancane kancane, i-pressure roller yomshini we-pellet we-biomass iphula izinto zokusetshenziswa ezisanhlamvu ezinkulu ngaphansi kwesenzo sokucindezela, iphenduke izinhlayiya ezinhle, futhi ukuguqulwa noma ukugeleza kwepulasitiki kwenzeka, izinhlayiya ziqala ukugcwalisa ama-voids, futhi izinhlayiya zihlangene kakhulu. Zihlangana zodwa lapho zithintana nomhlabathi, futhi ingxenye yokucindezeleka okusalayo igcinwa ngaphakathi kwezinhlayiya ezakhiwe, okwenza ukuhlangana phakathi kwezinhlayiya kuqine.

Ukuqina kwezinto ezingavuthiwe ezakha izinhlayiya ezibunjiwe, kuyanda izinga lokugcwalisa phakathi kwezinhlayiya kanye nokuqina kokuxhumana; lapho ubukhulu bezinhlayiya zezinhlayiya buncane ngezinga elithile (amakhulu kuya kuma-microns amaningana), amandla okubopha ngaphakathi kwezinhlayiya ezibunjiwe kanye nesisekelo kanye nesesibili ngisho nazo zizoshintsha. Izinguquko zenzeka, futhi ukukhanga kwamangqamuzana, ukukhanga kwe-electrostatic, kanye nokunamathela kwesigaba se-liquid (amandla e-capillary) phakathi kwezinhlayiya kuqala ukukhuphuka ukubusa.
Ucwaningo luye lwabonisa ukuthi i-impermeability kanye ne-hygroscopicity yezinhlayiya ezibunjiwe zihlobene eduze nobukhulu bezinhlayiya zezinhlayiya. Izinhlayiya ezinosayizi wezinhlayiyana ezincane zinendawo enkulu ethize, futhi izinhlayiya ezibunjiwe kulula ukumunca umswakama futhi ziphinde zibuyise umswakama. Encane, i-voids phakathi kwezinhlayiya kulula ukugcwalisa, futhi ukucindezelwa kuba kukhulu, ukuze ukucindezeleka kwangaphakathi okusele ngaphakathi kwezinhlayiya ezibunjiwe kube kuncane, ngaleyo ndlela kunciphise i-hydrophilicity yezinhlayiya ezibunjiwe futhi kuthuthukise ukungakwazi ukungena kwamanzi.

Ocwaningweni lokuwohloka kwezinhlayiyana kanye nefomu elibophezelayo ngesikhathi sokucindezelwa kwezinto zezitshalo, unjiniyela wezinhlayiyana wenza ukubhekwa kwe-microscope kanye nezinhlayiyana isilinganiso sobubanzi obuyisilinganiso esiphindwe kabili sezinhlayiya ezingaphakathi kwebhulokhi yokubumba, futhi wasungula imodeli yokubopha eyizinhlayiyana ezincane. Ekuqondeni kokucindezeleka okuyinhloko okuyinhloko, izinhlayiya zidlulela endaweni ezungezile, futhi izinhlayiya zihlanganiswa ngendlela ye-mutual meshing; ekuqondeni okuhambisana nokucindezeleka okukhulu okuyinhloko, izinhlayiya ziba mncane futhi zibe ama-flakes, futhi izingqimba zezinhlayiya zihlanganiswa ngendlela yokuhlanganisana.

Ngokwale modeli yenhlanganisela, kungachazwa ukuthi lapho izinhlayiya ze-biomass zithambile, kuba lula kakhulu ukuthi ububanzi obuyizingxenye ezimbili zezinhlayiya bube bukhudlwana, futhi kulula ukucindezelwa nokubunjwa kwe-biomass. Lapho okuqukethwe kwamanzi endaweni yezitshalo kuphansi kakhulu, izinhlayiya azikwazi ukunwetshwa ngokugcwele, futhi izinhlayiya ezizungezile azihlanganisiwe ngokuqinile, ngakho azikwazi ukubunjwa; lapho okuqukethwe kwamanzi kuphezulu kakhulu, nakuba izinhlayiya zinwetshwa ngokugcwele ekuqondeni kwe-perpendicular kuya ekucindezelekeni okukhulu okuyinhloko, Izinhlayiya zingahlanganiswa ndawonye, ​​​​kodwa njengoba amanzi amaningi kumpahla eluhlaza akhishwa futhi asakazwa phakathi kwezingqimba zezinhlayiya, izingqimba zezinhlayiya azikwazi ukunamathela eduze, ngakho azikwazi ukwakhiwa.

Ngokusho kwedatha yesipiliyoni, unjiniyela oqokwe ngokukhethekile wafinyelela esiphethweni sokuthi kungcono ukulawula usayizi wezinhlayiya zempahla eluhlaza ngaphakathi kwengxenye eyodwa kwezintathu yobubanzi bokufa, futhi okuqukethwe kwempushana akumele kube ngaphezu kwalokho. 5%.
