I-ring die kanye ne-roller ye-Pellet mill yizingxenye ezibaluleke kakhulu ezisebenzayo nezigqokekayo. Ukuqonda kokucushwa kwemingcele yabo kanye nekhwalithi yokusebenza kwabo kuzothinta ngokuqondile ukusebenza kahle kokukhiqiza kanye nekhwalithi ye-pellet ekhiqizwayo.
Ubudlelwano phakathi kwe-Diameter ye-ring die kanye ne-rola ecindezelayo kanye nokusebenza kahle kokukhiqiza kanye nekhwalithi yomshini we-Pellet:
I-ring-diameter die kanye ne-press roller pellet mill ingakhuphula indawo yokusebenza ephumelelayo ye-ring die kanye nomphumela wokucindezela we-press roller, engathuthukisa ukusebenza kahle kokukhiqiza, ukunciphisa izindleko zokugqoka kanye nezindleko zokusebenza, ukuze impahla idlule. inqubo ye-granulation ngokulinganayo, gwema i-extrusion ngokweqile, futhi uthuthukise ukuphuma kwe-Pellet mill. Ngaphansi kwenkomba efanayo yokucisha nokufudumala kwezinga lokushisa nokuqina, kusetshenziswa indandatho enobubanzi obuncane futhi amarola okucindezelayo kanye nendandatho yobubanzi obukhulu iyafa namarola okucindezela, ukusetshenziswa kwamandla kunomehluko osobala wokusetshenziswa kwamandla. Ngakho-ke, ukusetshenziswa kwendandatho enobubanzi obukhulu kanye ne-pressure roller kuyisilinganiso esisebenzayo sokunciphisa ukusetshenziswa kwamandla ku-granulation (kodwa kuya ngezimo ezithile zezinto ezibonakalayo kanye nesicelo se-granulation).
Isivinini Sokuzungezisa Iringi:
Ijubane lokuzungezisa lendandatho yokufa likhethwa ngokuya ngezici zempahla eluhlaza kanye nobukhulu bobubanzi bezinhlayiyana. Ngokusho kokuhlangenwe nakho, indandatho enobubanzi bembobo encane kufanele isebenzise isivinini somugqa ophezulu, kanti indandatho enobubanzi bembobo yokufa kufanele isebenzise isivinini somugqa ophansi. Isivinini somugqa we-ring die sizothinta ukusebenza kahle kwe-granulation, ukusetshenziswa kwamandla nokuqina kwezinhlayiya. Ngaphakathi kwebanga elithile, isivinini somugqa weringi siyakhuphuka, okukhiphayo kuyanda, ukusetshenziswa kwamandla kuyanda, futhi ubulukhuni bezinhlayiya kanye nenkomba yezinga lokuphulukisa liyakhuphuka. Ngokuvamile kunenkolelo yokuthi lapho ububanzi bembobo yokufa ingu-3.2-6.4mm, isivinini esikhulu somugqa we-ring die singafinyelela ku-10.5m/s; ububanzi bembobo yokufa yi-16-19mm, isivinini esiphezulu somugqa wokufa kwendandatho kufanele silinganiselwe ku-6.0-6.5m/s. Endabeni yomshini onezinjongo eziningi, awufaneleki ukusebenzisa isivinini somugqa owodwa wendandatho eyodwa kuphela ezinhlotsheni ezihlukene zezidingo zokucubungula okuphakelayo. Njengamanje, kuyisimo esivamile ukuthi ikhwalithi ye-granulator emikhulu ayilungile njenge-granules encane lapho ikhiqiza ama-granules anobubanzi obuncane, ikakhulukazi ekukhiqizeni imfuyo kanye nokudla kwezinkukhu kanye nokudla kwasemanzini okunobubanzi be-diameter. ngaphansi kuka-3mm. Isizathu siwukuthi isivinini somugqa wokufa kwendandatho sihamba kancane futhi ububanzi be-roller bukhulu kakhulu, lezi zici zizobangela isivinini sokubhoboza sento ecindezelwe ukuthi sisheshe kakhulu, ngaleyo ndlela kuthinte ubulukhuni nokufiphala kwenkomba yezinga lezinto ezibonakalayo.
Imingcele yezobuchwepheshe efana nokuma kwembobo, ukujiya kanye nezinga lokuvula lendandatho iyafa:
Umumo wembobo nogqinsi lwendandatho yokufa kuhlobene kakhulu nekhwalithi nokusebenza kahle kwegranulation. Uma i-diameter yokuvula indandatho incane kakhulu futhi ubukhulu bukhulu kakhulu, ukusebenza kahle kokukhiqiza kuphansi futhi izindleko ziphezulu, ngaphandle kwalokho izinhlayiya zikhululekile, okuthinta ikhwalithi nomphumela we-granulation. Ngakho-ke, ukwakheka kwembobo nokuqina kwe-ring die kuyimingcele ekhethwe ngokwesayensi njengesisekelo sokukhiqiza okuphumelelayo.
Umumo wembobo yokudayela kwendandatho: Izimo zembobo yokudaya ezivame ukusetshenziswa ziyimbobo eqondile, imbobo enesitebhisi ehlehlayo, imbobo yokubuyisela ecijile engaphandle kanye nembobo enwetshiwe ebheke phambili.
Ubukhulu bendandatho efayo: Ugqinsi lweringi luthinta ngqo amandla, ukuqina kanye nokusebenza kahle kwegranulation kanye nekhwalithi yokufa kweringi. Emazweni omhlaba, ukujiya kwedayizi kungu-32-127mm.
Ubude obusebenzayo bomgodi wokufa: ubude obusebenzayo bomgodi wokufa bubhekisela kubude bembobo yokufa ukuze kukhishwe impahla. Ubude obusebenzayo bembobo yokufa isikhathi eside, isikhathi eside sokukhipha emgodini wokufa, i-pellet izoba nzima futhi iqine.
Ububanzi be-conical inlet yembobo yokufa: ububanzi bokungena okuphakelayo kufanele kube kukhulu kunobubanzi bomgodi wokufa, okunganciphisa ukumelana nokungena kwento futhi kusize ukungena kwento ku-Die hole.
Izinga lokuvula leringi: Izinga lokuvula lendawo yokusebenza yeringi linomthelela omkhulu ekusebenzeni kahle kokukhiqiza kwe-granulator. Ngaphansi kwesimo samandla anele, izinga lokuvula kufanele lenyuswe ngangokunokwenzeka.
