I-Screens ezingavimba kwi-industri yesiphambano: Ukwahlukanisa izinto ezinxenye

Ukuthini Kusikrini Sokuvibrata Kwenza Ukwahlukaniswa Okuhle Ngokwesayizi

Izikhala zokuvibrata zifinyanwiswa ukwahlukaniswa ngokwesayizi kumsebenzi wokubuyisa usebenzisa indlela yokuvibrata eyalungelwe. Lokhu kuhlenza izinto ngokwesayizi sezinto, kuvulela ukutholakala kwezinto ezinomthelela kumthwalo onzima wemphakathi yamahewu.

Imikhuba Yoku-Vibrata Nezinhlelo Zokwahlukaniswa Kwesithunzi

Kumhla kwezinhlelo lezi zikhomba izindlela eziphambene noma izixhobo ze-electromagnetic ezenza ukuthembeka okulungelwe. Uma imithombo ivela kusayizi sokucaca, lokhu kuthembeka kuyenza izinto zihlukane ngokwabo. Izinto ezincane ziphazamiseka phansi kuzinkinga phakathi kwazo ezinkulu, futhi izinto ezinkulu ziyotiya endaweni eshiywa khona yisithuthi. Konke lokhu kusebenza ngoba izinto ezahlukene ngokwazo zihlanganisa ngendlela eyahlukene ngokwesimo, ubunzima, nokuthi zingaphantsi kangakanani ekugcineni. Ukubheka okutholakele kumsebenzi wokuphatha inkunkuma, izinye zezinhlelo zisebenza kahle kunazo ngokuthembeka okungekho mpaka we-3 ukuya ku-5 milimita. Kulokho kuthinta ukuchithwa kwezimali, lo msebenti ungahlinza izinto ngaphezu kuka-90% uma konke kuyilungiswa kahle.

Usayizi we-Mesh, Isikhathi, ne-Amplitude: Ukuqinisa i-Vibrating Screen yokufaka kwe-Recycling

Abasebenzisi bahlela amathuba amathathu abalulekile kumzila wokurekhoda:

• Ukukhetha kwe-Mesh : Iqinisekisa ubude bokugqogqa okuncane kakhulu (isb., ikheshi le-10 mm kuma-PET flakes kunokuthi ikheshi le-50 mm kuma-C&D debris)
• Ukulungiswa kwezilinganiso : Izilinganiso ezaphezulu (15–25 Hz) zenhance ukwahlukaniswa kwezinto ezincane; izilinganiso ezincane (10–15 Hz) zilinda ubunzima bezinkinga kodwa zidinga ukulungiswa okucophele kungakhathalwa ukuthi kuhlolwe izinto ezincane kumsebenzi wokuhlola izinto eziphuma kuzithembiso
• Ukubeka isivinini : Ukongeza kwebude lokuhlukahluka kuthuthukisa ukudluliswa kwezinto ezinde njengezilimi kodwa kudinga ukulungiswa okucophele ungakhathalwa ukuthi kuhlolwe izinto ezincane kumsebenzi wokuhlola izinto eziphuma kuzithembiso

Izikhungo zokubuyisa izinguquko zithola ukuthi kunezinkinga ezi-30% ngapha kwizinkinga ezingaphaya uma lezi ziqinisekiso ziqhawaniswa nge-analisi yomthwalo. Kumaqatha wamaplastiki, ukudibanisa izilinganiso ze-20 Hz ne-ikheshi ephinde-phinde yendawo ethembekile ibonisa ukuthi iphathelene ngaphezulu kuka-40% kunazo zodwa zokudluliswa kwezinto ezincane

Ukusetshenziswa Kwesikrini Esivuthayo Kusuka Kuzo Zonke Izinqumo Ezibalulekileyo Zokubuyisa

Ukubuyisa Okudluliselwe Ngokuthi Kugcwele Futhi Isakhiwo & Ukudweba (C&D) Izinkinga

Iscrimi ezivuthelayo zinika iziphumo ezikhulu kumsebenzi wokuphinda ukusebenzisa into eyodwa lapho zombili izinto ezahlukene njengebhotile yamapulastics, ikinisi zamathambo, nezinto zebhurekhu zonke zafakwa ngokuphelele. Isenzo sokuthwasa okusheshayo sivikela izinto ezahlukene ngosayizi ukuze abasebenzi bangakhetha konke ngendlela yokwenza khona. Xa kufundiswa ngamathuba okwehla nokwebisa akhwehliwe ngezinkunkuma zeconcrete, izici zezindlu, nezimboni zamathambo, lezi zinhlayiya zisebenza kahle ekukhupheleni kwizinto ezisetshenziswayo kusuka empile yesibindi. Kuningi kwezinhlayiya ezintsha zinezimiso ezingavutshelwa okwenzela ukuthi kugcinwe izindleko zokusebenzisa izimpilo ngama-40% njengoba abalawuli basephaneleni babesilwa. Ezinye izikhungo zihlawula kangcono kunezintathu zingcamu ngohora ngokushesha ngaleso sizathoko. Abagcini bezindlu zokugcina zayithemba le zinombolo ngoba izikhungo esezishintshile iscrimi esibonakalayo sikhuphela izinkinga ezingu-30% ngaphezulu kwezinkinga namathambo kunabo abasebenzisa izindlela ezindala. Kuyakwazi ukuchaza kungani kangaka izikhungo zokuphinda ukusebenzisa ziyashintsha izixhumanisi zakho manje.

Ukusebenza Okutholakala Ngokwezinto: Iplastics, Imetali, Incazelo, Nezinto Ezihlathile

Ukumisa izikrini zobuhlungu ngokweqile kumaterializingcono kubangela ukuthi zifane ngcono emisebenzini yokuwothola futhi ezingaphezu kwemibiko. Xa kusekelwa kwezimali, izivibrhesi ezindingayo zisiza ekuskeleni i-PET flakes away from i-PVC impurities engakhethi kakhulu yokwakha i-static. Indlela yokuthola ubuti ibecaphula kakhulu, ishaka okuningi ukuze ithule amabhilasi abandayo besilika esihamba, okungaholela kucomphutha okanobuhlungu kangako njalo. Ukupakeka kwebhurembo kufanele ngamathuba alula angaqondene futhi aqaphe amathambo ethulwini futhi athole izinto eziphazanyayo ezingafaneleke, njengalezi zibhengezelo nezimali. Kwezindleko zezinhloso, izinxenye ezithile zezikrini zisenza kube lula ukuthola izinto eziphansi kuzo ukuthi zizange zibe comphutha, zisenza kube khona amandla aphathelene kakhulu ekugcineni komphakathi wokugcina. Ukulungisa izinto ezifana nomkhawulo webheshi, amabhagi evibration, kunye nesilinganiso semandla sisenza siphume ngcono xa kusekelwa kumateriali ngamunye. Amakhampusi aninjalo angaba ngu-90% uma afuna izimo ezifanele zomfanekiso wabo.

Ukuphakamisa Ubungakanani Bekusetyenziswa: Ukulungisa Ukubandakanywa, Ukugcwalisa, nokuthwala

Izizathu kanye Nezinzo zokubandakanywa Kwesikrini Kwi-Scrap ezingavumelani

Kusetyenziswa okubandakanywa kumelela xa izinto ezinemibango eyedlule (0.8–1.2× usayizi wefuko) kufakwa emaphandleni, okuchitha indawo efanelekileyo yokusetyenziswa ngama-30–50% kumthwalo wokubuyisela. Umphuma unyusa le ngxenye kwiskrapi eningavumelani, okubangela ukuba izinto ezincane ziphakamise emayurhandleni. Iziphumo ezibaluleke kakhulu zilandela:

• Ukulungisa kwe-vibration : Ukuongeza kwebhola noma isivinini kushintsha imithombo yomsebenzi ukuhlukulula izinto ezibekelwe
• Igadethi engalungelanga ukubandakanywa : Izithebe ze-rubber zixhaxha i-media ngexesha lokusebenza; iziqhamo (2–4 L/min ngomethe nje ububanzi) zilungisa ukunqamleza kwezinto
• I-media eqhubeka ngaphezu : Izihlangothi ze-polyurethane ezicatha ngokujulile ngaphezu kwezibonakude zobumba zolungisa incinane ngama-40%

Ukugcinwa kwezinkinga ezihlukene kumakhasini e-screen kuyakhathazeka kakhulu futhi kuyaphazanyiswa, njengoba kuboniswa ngokuphazanyiswa kuka-30% kwenkinga yobulindi ebandleni lomphakathi [I-Journal yeMining Technology, 2022]. Lokhu kugcinwa kuyaqinisekisa ukuthuthana okuphathelene kumakhasini aphazanyayo aphathelana nendlela eyahlukene yokuphazanya.

Imipho Emya Yobuqiniso Nezempilo Yemikhumbi Ephazanyayo

Ukusebenzisa kwezivivinyo zokuvibisha kuletha izimali eziphethilene nokuphila kwemvelo kuzindawo zokubuyisela izinto ezasebandleni ngokujulile. Xa lezi zixhobo ziphakamisa izinto ezahlukene zonke, zakhula ubunjani bezoziswa nge-15 kuze kube ngu-30 iphesenti. Lokhu kusho ukuthi kuthengwa ngemali engele, kanti nezindleko zokulahla izinto emaphilakalini zingaphansi. Izinkampani eziningi zazithola izindleko zokuphatha ziphansi kwe-20 kuze kube ngu-40 iphesenti ngokuphethile njengoba kungaphansi kokudinga abantu ukuphakamisa futhi amashine angaphansi kokugcwaliseka. Ngokwemvelo, imiphumela iyisinkinga futhi. Izingqayizivele ziyakhokha kangakanani 95 iphesenti yezindleko zazo ezenziwa ngaphandle kwemaphilakalini nguye ngonyaka. Cabanga ngale dhlaka: ekulinganeni nothinta-thontha olufana nokuthintwa kwegumbi elingu-1.2 million ye-oli nganye indawo ngonyaka. Okunzima kakhulu, izinhlelo ezintsha ephathelene nemali etholakala zikhipha ukusetshenziswa kwamandla wamagugu ngeququ kabili kunazo ezintandazayo, okwenzekayo kancane kancane kunciphisa ukusungwa kwacarbon. Ngokujulile, izinkampani eziningi zibona ukuthi uhlelo lwabo luhlala libuyise izimali kubo phakathi kwe-6 izinyanga kuya ku-18 izinyanga, ngaphezu kwalokho bafakazeka kangcono ngokwemfundo yazo mayelana negunya lamandla.

Imibuzo Evame Ukubuzwa

Ivibrating screens zisetshenziswa ngani ekubeni kususwa izinto?

Izivivinyo zisetyenziswa ukwahlukanisa ngokuchaza ubungakanani kumsebenzi wokukhupha. Zisetyenzisa indlela esihlupheko esihle ukuze zihlanjise izinto ngokwesayizi yesithombe futhi zinikeze amandla okukhupha kakhulu kuzindlela ezikhulu zenzo.

Kunjani ivibrating screen ihlanganisa izinto?

Izivivinyo zihlanganisa izinto ngokuhlinzeka okuhle kakhulu okuvulela izithombe ukuthi zihlanganise ngokwesayizi, isimo, nombango. Izithombe ezincane zihlatshulwa ezinkatini, kodwa ezingaphezu kuzo zihamba endaweni yokunquma.

Yiziphi izici ezibalulekileyo ekulungiseni izivivinyo?

Izici ezibaluleke kakhulu ngu- mesh selection, frequency adjustment, ne-amplitude control. Umfanekiso uhlinza isayizi yesithombe, ukuguquka kuyaphatha inkambo yokuhlukaniswa, kanti amplitude ikhankanya inani lezinto eluhlaza kanye noluhlazo lwazo.

Yiziphi izintuthuko zokusebenzisa izivivinyo emathengelweni akhupho?

Amasikrini ahoxisayo ayakhula ubunjwala bokucaca, ayaphula izindleko zokuphatha, ayavutha izinguvo zokubuyisela, futhi ayasebenzisa umbono wempilo ngokuncipha okugcineni kwezimali nezimali.
