I-Cone Milling
Izigayo ze-cone, noma izigayo zesikrini se-conical, zisetshenziswe ngokwesiko ukunciphisa usayizi wezithako zemithi ngendlela efanayo. Kodwa-ke, nazo zingasetshenziselwa ukuxuba, ukusefa nokuhlakazwa. Ziza ngosayizi abahlukahlukene, okuhlanganisa nezisetshenziswa zelabhorethri ye-tabletop kuya kumishini egcwele, enekhono eliphezulu esetshenziselwa imisebenzi emikhulu yokucubungula imithi.
Nakuba ukusetshenziswa kwezigayo ze-cone kuhluka, ukuthambekela kokuzisebenzisa emithini yemithi kuhlanganisa ukukhipha izinto ezomisiwe ngesikhathi sokukhiqiza; ukulinganisa izinhlayiya ezimanzi ze-granulated ngaphambi kokumiswa; kanye nokulinganisa izinhlayiya ezomile ezigayiwe ngemva kokuba zomisiwe nangaphambi kokufakwa kwethebhulethi.
Uma kuqhathaniswa nobunye ubuchwepheshe bokugaya, isigayo se-cone siphinde sinikeze ezinye izinzuzo ezithile kubakhiqizi bemithi. Lezi zinzuzo zihlanganisa umsindo ophansi, ubukhulu bezinhlayiyana ezifanayo, ukuguquguquka komklamo kanye nomthamo ophezulu.
Ubuchwepheshe bokugaya obusha kakhulu emakethe namuhla buhlinzeka ngokuphuma okukhulu nokusabalalisa usayizi womkhiqizo. Ngaphezu kwalokho, ayatholakala nge-sieve eguquguqukayo (isikrini) nezinketho ze-impeller. Uma isetshenziswa ngezinto eziminyanisa kancane, isisefo singanyusa ukuphuma ngamaphesenti angaphezu kuka-50 uma kuqhathaniswa nezigayo eziklanywe ngezinsimbi eziqondile. Kwezinye izimo, abasebenzisi bathole umthamo wokukhiqiza weyunithi ongafika kumathani ama-3 ngehora.
Ukuzuza Ukugaywa Kwekhoni Okungathuli
Kwaziwa kahle ukuthi ukugaya kukhiqiza uthuli, okungaba yingozi ikakhulukazi kubaqhubi kanye nendawo yokucubungula imithi uma uthuli lungekho. Kunezindlela eziningana ezitholakalayo zokuvimbela uthuli.
Ukugaya i-bin-to-bin kuyinqubo esemgqeni ngokugcwele ethembele kumandla adonsela phansi ukuze kuphakelwe izithako ngomshini wekhoni. Ochwepheshe babeka umgqomo ngaphansi kwesigayo, futhi umgqomo obekwe ngokuqondile ngaphezu kwesigayo ukhiphela izinto ezisetshenziswayo emshinini. Amandla adonsela phansi avumela okokusebenza ukuthi kudlule ngokuqondile esitsheni esingaphansi ngemva kokugaya. Lokhu kugcina umkhiqizo uqukethwe kusukela ekuqaleni kuze kube sekupheleni, futhi kwenza ukudlulisa okubalulekile kube lula ngemva kokugaya.
Enye indlela ukudluliswa kwe-vacuum, okubuye kube yinqubo esemgqeni. Le nqubo iqukethe uthuli futhi iphinde izenzele inqubo ukusiza amakhasimende afinyelele ukusebenza kahle okuphezulu nokonga izindleko. Besebenzisa isistimu yokudlulisa i-vacuum esemgqeni, ochwepheshe bangaphakela izinto ezisetshenziswayo nge-chute ye-cone futhi bazikhiphe ngokuzenzakalelayo emshinini wokugaya. Ngakho, kusukela ekuqaleni kuya ekupheleni, inqubo ivalwe ngokugcwele.
Okokugcina, ukugaya i-isolator kunconywa ukuthi kuqukethe izimpushana ezinhle ngesikhathi sokugaya. Ngale ndlela, i-cone mill ihlanganisa ne-isolator ngokusebenzisa i-flange yokulungisa udonga. I-flange nokucushwa kwesigayo se-cone kuvumela ukuhlukaniswa ngokomzimba kwekhanda lokugaya i-cone ngendawo yokucubungula engaphandle kwesihlukanisi. Lokhu kulungiselelwa kuvumela noma yikuphi ukuhlanzwa ukuthi kwenziwe ngaphakathi kwesihlukanisi ngendlela yebhokisi lamagilavu. Lokhu kunciphisa ingozi yokuchayeka kothuli futhi kuvimbela ukudluliswa kothuli kwezinye izindawo zomugqa wokucubungula.
I-Hammer Milling
Izigayo ze-hammer, ezibuye zibizwe ngokuthi ama-turbo mill ngabakhiqizi abathile abalungisa imithi, ngokuvamile zilungele ucwaningo nokuthuthukiswa komkhiqizo, kanye nokukhiqizwa okuqhubekayo noma kwenqwaba. Ngokuvamile zisetshenziswa ezimeni lapho abathuthukisi bezidakamizwa bedinga ukunemba kwezinhlayiyana zokunciphisa ama-API okunzima ukuwagaya nezinye izinto. Ngaphezu kwalokho, izigayo zesando zingasetshenziswa ukubuyisela amaphilisi aphukile ngokuwagaya abe yimpushana ukuze aguqulwe.
Isibonelo, lapho ehlolwa, amanye amaphilisi akhiqiziwe angase angabi sezingeni lekhasimende ngenxa yezizathu ezihlukahlukene: ubulukhuni obungalungile, ukubukeka kabi, kanye nokukhuluphala noma ukukhuluphala ngokweqile. Kulezo zimo, umenzi angakhetha ukuwagaya amaphilisi abuyele esimweni sawo esiyimpushana kunokuthi alahlekelwe yizinto ezisetshenziswayo. Ukugaywa kabusha amaphilisi kanye nokuwabuyisela ekukhiqizeni ekugcineni kunciphisa ukumosha futhi kwandisa umkhiqizo. Cishe kuzo zonke izimo lapho iqoqo lamaphilisi lingahlangabezani nezicaciso, abakhiqizi bangasebenzisa isigayo sesando ukuze banqobe inkinga.
Izigayo zokugaya ziyakwazi ukusebenza ngesivinini esisukela ku-1,000 rpm kuya ku-6,000 rpm kuyilapho zikhiqiza amakhilogremu angu-1,500 ngehora. Ukuze kufezwe lokhu, ezinye izigayo zifika zifakwe i-valve ejikelezayo evumela ochwepheshe ukuba bagcwalise igumbi lokugaya ngokulinganayo ngezithako ngaphandle kokugcwalisa ngokweqile. Ngaphandle kokuvimbela ukugcwala ngokweqile, amathuluzi okuphakelayo anjalo angakwazi ukulawula ukugeleza kwempushana egunjini lokugaya ukuze kwandiswe ukuphindaphinda kwenqubo futhi kunciphise ukuphehla kokushisa.
Ezinye zezigayo zesando ezithuthuke kakhulu zinezinhlangothi ezimbili ezihlangene ezikhulisa ukusebenza kwezithako ezimanzi noma ezomile. Olunye uhlangothi lwensingo lusebenza njengesando sokuphihliza izinto ezomile, kuyilapho uhlangothi olunjengommese lukwazi ukusika izithako ezimanzi. Abasebenzisi bamane baphenye i-rotor ngokusekelwe ezithakweni abazigayo. Ukwengeza, amanye ama-mill rotor ahlanganayo angahlehliswa ukuze alungiselwe ukuziphatha komkhiqizo othize kuyilapho ukuzungezisa kwesigayo kuhlala kungashintshile.
Kwezinye izigayo zesando, usayizi wezinhlayiyana unqunywa ngokusekelwe kusayizi wesikrini okhethelwe isigayo. Izigayo zesando zesimanje zinganciphisa usayizi wempahla ube mncane njengo-0.2 mm ukuya ku-3 mm. Uma ukucubungula sekuqediwe, isigayo siphusha izinhlayiya esikrinini, esilawula usayizi womkhiqizo. I-blade nesikrini kusebenza ngokubambisana ukuze kunqunywe usayizi wokugcina womkhiqizo.
