Ungasikhetha kanjani isikrini esidlidlizayo sezinto ezahlukahlukene

Ukuze ukhethe isikrini esidlidlizayo sento ethile, udinga ukucabangela inhlanganisela yezinto ezibonakalayo, umphumela oyifunayo, kanye nezidingo zokusebenza. Uhlobo lwempahla, ukusatshalaliswa kosayizi wezinhlayiyana, okuqukethwe umswakama, nokuminyana yizici ezibalulekile. Udinga futhi ukuchaza umthamo odingekayo (amathani ngehora), usayizi wokuhlukaniswa okufunayo, kanye nezinga lokunemba kokuhlola elidingekayo.

Ungasikhetha kanjani isikrini esidlidlizayo sezinto ezahlukahlukene

Hlaziya Impahla Yakho Ebalulekile

1. Ukusabalalisa Usayizi Wezinhlayiyana (PSD):

Bungakanani usayizi wezinhlayiyana ezinkulu? Lokhu kunquma usayizi wokuvula okuphakelayo namandla esakhiwo adingekayo.

Ungakanani usayizi wezinhlayiyana ezincane kunazo zonke? Lokhu kubalulekile ekukhetheni indawo yokungena esikrinini.

Ingakanani iphesenti lento elungile uma iqhathaniswa namaholoholo? Iphesenti eliphezulu lezinhlayiya ezinosayizi oseduze (izinhlayiya ezisondelene kakhulu nosayizi wokuvuleka kwemeshi) lilukhuni ukuliboniswa futhi lidinga indawo yesikrini eyengeziwe noma ukunyakaza kwesikrini okusebenza kahle kakhudlwana.

2. Ukuma Kwezinhlayiyana:

I-Cubical/Spherical (isb., igravel, ama-pellets): Okulula kakhulu ukukusikrini. Zigeleza kahle futhi zidlula ezindaweni ezivulekile kalula.

I-Flaky/Elongated (isb., ama-wood chips, shale): Kunzima ukusikrini. Lezi zinhlayiya zingawela ngobude ngembobo ebezingeke zingene kuyo uma kungenjalo, noma zingahlala kumeshi (ukupheqa). Isikrini esinesenzo sokujikijela esinolaka singadingeka.

Okungajwayelekile (isb., itshe elichotshoziwe): Isimo esivame kakhulu, esinobunzima bokuhlola obumaphakathi.

3. Ukuminyana Kwenqwaba (Isisindo ngevolumu ngayinye, isb., lbs/ft³ noma kg/m ³):

Ukuminyana Okuphezulu (isb., insimbi yensimbi): Idinga isikrini esindayo esinohlaka oluqinile, iziphethu ezinamandla, kanye nenjini enamandla kakhulu ukuze ibambe umthwalo.

Ukuminyana Okuphansi (isb., ama-wood chips, ipulasitiki): Okubalulekile kungase kuhambisane nomoya uma ukudlidliza kunolaka kakhulu. Isenzo sokuhlola esithambile singaba ngcono.

4. Okuqukethwe Umswakama:

Omile (< 1% umswakama): Kulula ukusikrini.

Umswakama (1-5% umswakama): Kungaba yinkinga. Izinhlayiya ezinhle zingase ziqale ukunamathelana kanye nasesibukweni.

Kumanzi (> 5% umswakama) noma Okuludaka: Lokhu kuyisici esikhulu. Umswakama ophezulu udala izinhlayiya ezinhle ukuthi zinamathele kwezikhudlwana futhi zivale inezikhala zesikrini (ukuphuphuthekisa). Ungase udinge isikrini esikhethekile sokususa amanzi, imigoqo yesifutho samanzi, noma isikrini esinezici ezivimbela ukungaboni.

5. Okubalulekile “Ukunamathela” kanye Nokubumbana:

Okugeleza mahhala (isb., isihlabathi esomile): Ilungele ukuhlolwa.

Okunamathelayo/okuhlangene (isb., ubumba, inhlabathi emanzi): Kunzima kakhulu. Okubalulekile kuzophuphuthekisa i-mesh yesikrini ngokushesha. Uzodinga izikrini ezinamandla amakhulu, imidiya yesikrini evimbela ukuvala (njengezintambo zokuzihlanza), noma ubuchwepheshe bokuhlola obuhlukile ngokuphelele (njengesikrini se-trommel noma isikrini senkanyezi).

6. Ukuthuthumela:

I-Abrasive Highly (isb., i-granite, i-quartz, i-slag): Izoguga ngokushesha i-wire mesh evamile. Kufanele usebenzise imidiya yesikrini engazweli njengensimbi enekhabhoni ephezulu, i-polyurethane, noma irabha.

I-Non-Abrasive (isb., ama-pellets epulasitiki, imikhiqizo yokudla): Insimbi engagqwali evamile noma i-wire mesh yanele.

7. Izinga lokushisa:

Izinto Ezishisayo (isb., i-asphalt, i-sinter): Idinga izingxenye ezikhethekile, ezimelana nokushisa, ikakhulukazi kumidiya yesikrini (imeshi yensimbi iyadingeka, hhayi i-polyurethane noma irabha).

Chaza Isicelo sakho Sokuhlola

Uyini umgomo oyinhloko wenqubo yokuhlola?

I-Scalping: Isusa kuphela into enkulukazi enkulu ekuphakeleni. Lokhu ukuhlukaniswa okulukhuni, ngokuvamile ekuqaleni kwenqubo.

Ukulinganisa (noma Ukuhlukanisa): Ukuhlukanisa izinto zibe izingxenye ezimbili noma ngaphezulu ezinosayizi othize. Lolu uhlelo lokusebenza oluvame kakhulu futhi ludinga ukunemba okuphezulu.

I-Dewatering: Ukukhipha uketshezi entweni eqinile. Lezi zikrini zivamise ukuthambekela ekukhuphukeni futhi zisebenzisa ukudlidliza okunemvamisa ephezulu ukunyakazisa amanzi.

Ukususwa Kwezinhlawulo (De-dusting): Ukukhipha izinhlayiya ezinhle kakhulu (uthuli) emkhiqizweni omahhadla.

Izinhlobo Zesikrini Ezidlidlizayo
Izinhlobo zezikrini ezidlidlizayo ezihlukene zenzelwe izinhlelo zokusebenza ezithile nezinto ezibonakalayo.

Isikrini Esindindizelayo Esiyindilinga: Lezi zikrini zivame kakhulu futhi zisebenza ngezindlela eziningi. Basebenzisa ukunyakaza okuyisiyingi okudalwe yisisindo esingama-eccentric, okulungele ukuhlola uhla olubanzi lwezinto ezomile, ezimahhadla ezifana nama-aggregate namaminerali.

Isikrini Esidlidlizayo Esilayini: Lezi zikrini zisebenzisa ukunyakaza komugqa oqondile, osebenza kahle kakhulu ekukhipheni amanzi nasekuhloleni izinto ezicokeme, ezimanzi, noma ezinamathelayo. Ukunyakaza komugqa kusiza ukuhambisa okokusebenza eduze kwedekhi yesikrini ngenkathi futhi uyihlunga ukuze uvumele izinhlayiya ezinhle ukuthi zidlule.

Isikrini Esinemvamisa Ephakeme: Njengoba igama libonisa, lezi zikrini zisebenza ngemvamisa yokudlidliza ephezulu kakhulu kanye ne-amplitude encane. Lokhu kuzenza zilungele ukuhlola izinhlayiya ezinhle kanye nokukhipha amanzi, njengoba ukudlidliza okusheshayo kuvimbela umswakama ekubangeleni ukuphuphuthekisa.

Isikrini sikabhanana: Lolu hlobo lwesikrini lunedekhi egobile, enemithambeka eminingi. Umqansa wokuqala owumqansa uvumela ukuhlukaniswa ngokushesha nokususwa kwezinhlawulo, kuyilapho izigaba eziyisicaba zinikeza isikhathi esengeziwe sokuhlukaniswa kokugcina. Lo mklamo muhle kakhulu ezinhlelweni zokusebenza eziphezulu ezinamaphesenti aphezulu ezinhlayiya ezinhle.

Isikrini se-Grizzly: Lezi izikrini ezisindayo, ngokuvamile ezimile noma ezine-stroke eqondile, ehlanganisa imigoqo ehambisanayo noma ama-rails. Asetshenziselwa “i-scalping,” okuyinqubo yokukhipha amatshe amakhulu kakhulu noma izinto ezimahhadla ngaphambi kokuthi ingene ku-crusher eyinhloko.

Okungenhla yisingeniso esiphelele sokukhetha isikrini esidlidlizayo esifanele sezinto ezihlukile. Ukukhetha isikrini esidlidlizayo esilungile kubalulekile ekusebenzeni kahle, ikhwalithi yomkhiqizo, nezindleko zokusebenza. Kuyinqubo enezinyathelo eziningi ehlanganisa ukuhlaziya okokusebenza, ukuqonda isimo sohlelo lokusebenza, nokuqonda izinhlobo ezihlukene zezikrini.
