Idayi iyona nto ebalulekile emshinini wokugaya ama-pellet. Futhi iyisihluthuleloukwenza ama-pellet okuphakelayoNgokwezibalo ezingaphelele, izindleko zokulahlekelwa yi-pellet mill zingaphezu kuka-25% wezindleko zokulungisa yonke indawo yokukhiqiza. Ngokukhuphuka ngamaphesenti emali ekhokhwayo, ukuncintisana kwakho emakethe kwehla ngo-0.25%. Ngakho-ke imininingwane ye-pellet mill ibaluleke kakhulu.
I-Shanghai Zhengyi (CPSHZY) inguchwephesheumshini wokugaya ama-pelletumhlinzeki eShayina. Sihlinzeka nge-ring die pellet mill, i-flat die pellet mill kanye ne-izingxenye ze-pellet mill, njenge-flat die, i-ring die, i-pellet mill roller, nezinye izingxenye zomshini we-pellet.
1.Izinto zokudaya ze-pellet mill
Idayi yokugaya i-pellet ngokuvamile yenziwa ngensimbi yekhabhoni, insimbi yesakhiwo se-alloy noma insimbi engagqwali ngokusebenzisa i-forging, machining, ukubhoboza imigodi, kanye nezinqubo zokwelapha ukushisa. Umsebenzisi angakhetha ngokuya ngokugqwala kwezinto zokusetshenziswa kwezinhlayiya. Izinto zedayi yokugaya i-pellet kufanele zenziwe ngensimbi yesakhiwo se-alloy noma isikhunta sendandatho yensimbi engagqwali.
Insimbi yesakhiwo sekhabhoni, njengensimbi engu-45, ubulukhuni bayo bokwelashwa kokushisa ngokuvamile bungu-45-50 HRC, iyinto edayiwe ngendandatho esezingeni eliphansi, ukumelana kwayo nokuguguleka kanye nokumelana nokugqwala kuphansi, manje sekuqediwe ngokuphelele.
Insimbi eyakhiwe nge-alloy, njenge-40Cr, 35CrMo, njll., enobunzima bokwelashwa kokushisa obungaphezu kwe-50HRC kanye nezakhiwo ezinhle zemishini ezihlanganisiwe. Idayi eyenziwe ngale nto inamandla aphezulu kanye nokumelana nokuguguleka, kodwa ububi ukuthi ukumelana nokugqwala akukuhle, ikakhulukazi ekudleni izinhlanzi.
Intengo yama-ring dies, enziwe ngezinto zokwakha, ama-marigold pellets, ama-wood chips, ama-straw pellets, njll., iphakeme kakhulu kunensimbi engagqwali. Zombili i-20CrMnTi kanye ne-20MnCr5 ziyizinsimbi ze-alloy ezine-carburizing ephansi, zombili ziyafana, ngaphandle kokuthi eyokuqala iyinsimbi yaseShayina kanti eyesibili iyinsimbi yaseJalimane. Njengoba i-Ti, isakhi samakhemikhali, ingatholakali kwamanye amazwe, i-20CrMnTi noma i-20CrMn evela eShayina isetshenziswa esikhundleni se-20MnCr5 evela eJalimane, ngakho-ke ayiweli ngaphansi kwensimbi yesakhiwo se-alloy. Kodwa-ke, ungqimba oluqinile lwale nsimbi lukhawulelwe yinqubo ye-carburizing ibe ukujula okuphezulu okungu-1.2 mm, okuyinzuzo futhi yentengo ephansi yale nsimbi.
Izinto zensimbi engagqwali zifaka phakathi insimbi engagqwali yaseJalimane i-X46Cr13, insimbi engagqwali yaseShayina i-4Cr13, njll. Lezi zinto zinokuqina nokuqina okungcono, ubulukhuni bokwelashwa kokushisa obuphezulu kunezinsimbi ezifakwe i-carburi, izendlalelo eziqinile kunezinsimbi ezifakwe i-carburi, kanye nokumelana okuhle nokugqwala, okuholela ekuphileni isikhathi eside kanye namanani aphezulu ngokwemvelo kunezinsimbi ezifakwe i-carburi. Ngenxa yokuphila isikhathi eside kwensimbi edayiwe yensimbi engagqwali, imvamisa yokushintshwa iphansi ngakho-ke izindleko ngethani ziphansi.
Ngokuvamile, izinto zokwakha i-die ze-ring die pellet mill ziyinsimbi eyakhiwe nge-alloy kanye nezinto zensimbi engagqwali.
2.Isilinganiso sokucindezela se-pellet mill die
i=d/L
T=L+M
U-M ukujula komgodi oncishisiwe
Isilinganiso sokucindezela (i) yisilinganiso sobubanzi bembobo yokudaya (d) kanye nobude obusebenzayo (L) bedaya.
Ngokwemvelo yezinto zokusetshenziswa, isilinganiso singu-8-15, Umsebenzisi ukhetha isilinganiso sokucindezela sedayi, futhi ulungisa isilinganiso esithile sokucindezela, njengokukhetha isilinganiso sokucindezela esiphansi kancane, okuzuzisa ukwandisa umkhiqizo, ukunciphisa ukusetshenziswa kwamandla, ukunciphisa ukuguguleka kwesikhunta sendandatho, kodwa futhi kunciphisa ikhwalithi yezinhlayiya, njengokuthi ama-pellet awanamandla ngokwanele, ukubukeka kukhululekile futhi ubude buhlukile, futhi izinga lempuphu liphezulu.
3.Izinga lokuvula ledayi yendandatho
Izinga lokuvula le-pellet mill die liyisilinganiso sendawo iyonke yembobo ye-die endaweni iyonke esebenzayo ye-die. Ngokuvamile, lapho izinga lokuvula le-die liphezulu, kulapho isivuno sezinhlayiya siphezulu khona. Ngaphansi kwesisekelo sokuqinisekisa amandla e-die, izinga lokuvula le-ring die lingathuthukiswa ngangokunokwenzeka.
Kwezinye izinto zokusetshenziswa, ngaphansi kwesimo sesilinganiso sokucindezela esifanele, udonga lwe-pellet mill die luncane kakhulu, ngakho-ke amandla e-die awanele, futhi isimo se-die eqhumayo sizovela ekukhiqizweni. Ngalesi sikhathi, ubukhulu be-ring die kufanele bukhuliswe ngaphansi kwesisekelo sokuqinisekisa ubude obusebenzayo be-die hole.
4.Ukuqondanisa phakathi kwe-pellet mill die kanye ne-roller
Kuwubuchwepheshe obubaluleke kakhulu bokuthuthukisa ukusebenza kahle kwe-granulation nokwandisa impilo yedayi. Kufanele ifake izici ezine:
- Idayi entsha yendandatho ene-roller entsha yokucindezela, gwema ukusebenzisa ngokweqile i-roller yokucindezela.
- Ngokwemvelo yezinto zokwakha, izici zohlobo lomshini zokukhetha izinhlobo ezahlukene ze-pressure roller, ukuze kufezwe ukusebenza kahle kokukhipha phakathi kwe-die ne-roll.
- Isihluthulelo sokulingana kwesikhala ukuzinza futhi isimiso sithi: ngaphandle kokuphazamisa umthamo, zama ukuphumula.
- Lawula isivinini sokudla, lungisa isikhundla eside nesifushane se-feed scraper ukulawula isikhundla sokudla, ukusatshalaliswa kwengqimba yezinto ezibonakalayo.
5.Ukucutshungulwa kwenqubo yokufa kwe-pellet mill
Izimbobo ze-ring die zidinga kakhulu ngokwemishini yokucubungula nokucubungula, futhi ngensimbi engagqwali, kudingeka imishini ekhethekile yokugaya izibhamu kanye nemishini yokwelapha ukushisa kwe-vacuum ukuze kukhiqizwe ama-ring die asezingeni eliphezulu. Inqubo enhle kakhulu yokucima i-vacuum eshisa kakhulu ingathuthukisa kakhulu ukuqina, ubulukhuni, ukumelana nokuklwebheka, amandla okukhathala kanye nokuqina kwensimbi. Kodwa-ke, ikhono lokuqinisekisa ungqimba lobunzima obulinganiselayo kuyo yonke imbobo ye-die lidinga izinga eliphezulu lamakhono okucubungula kanye nesipiliyoni eside.
6.Ubulukhuni bomphezulu wezinsika zodonga lwangaphakathi lomgodi wezinsika
Ukungalungi kobuso nakho kuyinkomba ebalulekile yekhwalithi yedayi yendandatho. Ngokuvamile, inani elincane lokungalungi kobuso bodonga lwangaphakathi lizothuthukisa ikhwalithi yokulingana, linciphise ukuguguleka futhi landise impilo yedayi yendandatho, kodwa izindleko zokucubungula idayisi yendandatho zizokwanda.
Ubulukhuni bembobo yendandatho buthinta nesilinganiso sokucindezela kanye nokwakheka kwezinhlayiya, kanye nokusebenza kahle kokukhiqiza. Ngesikhathi esifanayo sokucindezela i-ring die, lapho inani lobulukhuni liphansi, lapho ukumelana kokukhipha kwezinkuni noma ukudla kuncipha, lapho ukukhishwa kubushelelezi khona, ikhwalithi yama-pellets akhiqizwayo iyanda futhi ukusebenza kahle kokukhiqiza kuyanda. Ukucubungula kahle imbobo ye-ring die kungaba ngama-microns angu-0.8-1.6, ubulukhuni be-ring die bungaba ngama-microns angu-0.8, umshini ofanele ezintweni ezilahlwayo, akukho ukugaya.
