Ukubala Ukukhula Kwesikrashi Sasezindini Ngokusebenza Kwemithombo Yezindini

Kwizindawo zokukhishwa kwezintsholongwane nezokuproducwa kwezintsholongwane, ukukhetha isikhumba sezibambo esihlukileyo nokubala ngokulinganisa isivinini sakho kubizwa ngokuthi kubalulekile kakhulu kusukela ekutheni kuyaphatha ngokuhle, ukunciphisa izindlela zokuthengisa, nokubeka isikhathi sokuphatha kwezinye izinhlangano ngokuhlukileyo.

Kubazomkhakha njenge-Zhongyu Dingli, abaneminyaka eyingu-30 yokuqonda izinto zokukhishwa kwezintsholongwane nezokusebenza kwezinto zokwakha, nokusebenza kwezinkinga zokugcina (EPC), ukubala isivinini akuyi nje indlela yokubala ngokuthetheka; kuyi nje indlela yokusebenza okufanele ukuthi isikhathi sokuphatha kwenziwe ngokuhle nokuthola isiphumo esihlukileyo.

Le ngculazi iyachaza indlela yokubala isivinini sesikhumba sezibambo, izinto zokuthi ziyaphatha kanjani, nokuthi abasebenzi bokukhishwa bakayisebenzisa lezi zindlela kwezindlela zokukhishwa zokusebenza ngempela.

Ukuziqonda Isivinini Sesikhumba Sezibambo

Umthamo womshini wokuchoboza umhlathi ngokuvamile ubhekisela enanini lezinto umshini ongazicubungula ngehora, ngokuvamile elivezwa ngamathani ngehora (TPH). Nokho, umthamo wangempela awuyona inombolo eqondile; uyahlukahluka kuye ngezici zento, ukwakheka komshini, nezimo zokusebenza.

Ngokuvamile abakhiqizi banikeza amandla angokombono asekelwe ezimweni zokudla ezinhle. Ezimweni zangempela zokumbiwa kwemigodi, amandla asebenzayo ngokuvamile aphansi ngenxa yokungahleleki kokudla, umswakama nezimo zokugqoka.

Ifomula eyisisekelo yamandla omshini wokuchoboza umhlathi

Ifomula elula yemfundiso evame ukusetshenziswa emkhakheni wobunjiniyela yile:

• Amandla (Q) = (60 × isilinganiso sokudla × ububanzi bokuvula kokukhishwa × ukunciphisa isici)

Nokho, indlela yokusondela emkhakheni ongokoqobo yile:

• Q = A × B × C × D

Lapho:

• A = Indawo yokuvula yokudla noma isici sobubanzi

• B = Ubukhulu bezinto ezibonakalayo

• C = I-stroke kanye ne-speed factor

• D = Ifaktor yokusebenza (kubizwa ngokujwayelekile ku-0.6–0.8 emisebenzini yezinhlelo zokusebenza)

Nakuba izinhlelo zokusebenza zingase zisetyenziswa ngabaphambili, le ndlela yokuqondisa isikhundla esihle kusukela emaqhingweni okuqala wezinhlelo zokusebenza isiza abahayi endaweni yokubala ukukhula.

Izinkomba Ezibalulekile Zokuthintana Nokukhula

Usayizi Wokufaka Nomkhawulo

Usayizi wokufaka okuphezulu kakhulu kuyathintana ngqo nokusebenza kwesikhundla sokugcina. Kusukela kwezinye izindaba, umfanekiso wokufaka kufanele kube nomkhawulo othile futhi akufanele ukhulula ama-80–90% wezinhlelo zokufaka. Ukufaka okungafanani kungadlula ngokuphelele ukukhula.

Ubunzima Bomfanekiso Nobuhlebhu

Amasayizi amabi kakhulu njenge-granite noma basalt ayakhiwana ukusebenza kokugcina futhi ayakhula ukugcina kwezinhlelo zokugcina. Amasayizi amabi kakhulu njenge-limestone angavumela ukukhula okuphezulu.

Ubunzima Bemifula

Ukukhula kwezimithi eziningi kungasiza ukuthi umfanekiso uhlale futhi ugcine, okukhula ukukhula okusebenzayo. Emaphakathi engezinye ezingenamandla, kudingeka ukuthatha izindlela zokuhlola okunye noma ukusebenzisa izindlela zokuphela kabusha.

Isidingo Sokugcina Sasezantsi (CSS)

I-CSS ichaza ubukhulu besiphumo sokugcina futhi isebenzisa kakhulu ukubala kwesikhundla. i-CSS encane iyaproducisa imithombo emincane kodwa iyanciphisa ukubhukuda.

Ispeed yomshakathi wokuphatha nokuhamba kwejaw

Ispeed yomshakathi wokuphatha nokuhamba kwejaw kubangela ukuthi imithombo ihambisana kangakanani. Ispeed ephakeme kungakwazi ukuncipha isikhundla kodwa kungakwazi ukuncipha ukusebenza kwezinto zokuphatha nokunyusa ukusebenza kwamandla.

Indlela Yokubala Isikhundla Sokusebenza Ngokwemboni

Kumaphrojekthi wequarry, abengineya badelela indlela yokubala ngokulandela izinyathelo:

Inyathelo 1: Qinisa Iziphakamiso Zomthombo

• Uhlobo lwemithombo (isibonelo, i-limestone, i-granite)

• Ubulukhu bekhanda (t/m³)

• Usayizi ophezulu lwokunyanga

Inyathelo 2: Khetha Imodeli Yomshakathi Wokuphatha

Ngokwesikhundla esidingekayo nokubhukuda kokufaka, khetha imodeli yomshakathi wokuphatha wejaw ene-dimensions zokufaka ezifanele.

Isinyathelo 3: Sebenzisa Imboni Yekhapa Yesivuthi

Sebenzisa ikhapa yesibalo esinikwa ngumshayeli wemithombo ngemizamo eyisisekelo.

Isinyathelo 4: Sebenzisa Amaphakamiso Okuhlela

Hlela ikhapa yesibalo ngamaphakamiso okuhlela:

• Ifaktor yokubonakala kwesifundo (0.7–1.0)

• Ifaktor yokuphakeme kwezinto (0.5–1.0)

• Ifaktor yokumusha (0.6–1.0)

• Ifaktor yokusebenza kahle (0.6–0.85)

Isinyathelo 5: Bala Ikhepha Elinikezwe

Ikhepha yokuqhubeka = Ikhepha yesibalo × Amaphakamiso okuhlela akhiwe ngokuphelele

Isibonelo Sesilinganiso

Siyakhathazeka:

• Ukukhala kwe-theoretical = 300 TPH

• Ifaktor yokuthi isithunywa sikhona = 0.85

• Ifaktor yokuphakeme = 0.75

• Ifaktor yokumusha = 0.9

• Ifaktor yokusebenza ngokwanele = 0.8

Ukukhala okusebenzayo:
300 × 0.85 × 0.75 × 0.9 × 0.8 ≈ 137 TPH

Lokhu kubonisa ukuthi imithombo yezimo zokusebenza kwesikhathi esihlukene kungabuyisela ngokuphelele ukukhala okwenzelwe.

Umkhankaso we-System-Level Design

Ukukhokha kwe-Jaw crusher akufanele kube kubhekwa ngokwesibonelo. Kusetyenziswa kwesiquletho sokuphatha kwesiquletho, ukukhokha kufanele kube yilokho:

• Ukukhokha kwe-Vibrating feeder

• Ispeed yebhelti yekhonveya

• Ukukhokha kwe-Cone crusher noma kwe-Impact crusher ekuseni

• Ukukhokha kwe-Screening plant

Uma isikhathi esinye sikhula kancane, izibonko zizoba zisindisa ukusebenza kweziquletho zonke.

Lokhu ke ubunzima obukhuluma ngalo abaprofayili be-EPC njenge-Zhongyu Dingli bafuna ukuthi baphinde bakhetha ukuthi badele isistimu esiyinqanaba esihle ngakumbi kunokuthi badele imishini engamnye kuphela. Isiquletho esihle sokukhokha sisinika ukuphatha okuphelele nokuthula kwezindlela zokusebenza.

Izimbalwa eziphathelene nokukhokha

Abaprofayili base-siquletho abaningi bafana nezimbalwa zokuthi:

• Ukubazisa kuphela kwezinkundla zokugcina ngaphandle kokulungiswa

• Ukuhlonipha ukuchaphazeka kwemithombo kuzindawo ezahlukene zezindlu zokugcina

• Ukuqiniseka kakhulu ukusebenza kwe-crusher

• Ukuhlonipha isikhathi sokuvutha kwezinhlelo zokusebenza

• Ukudesigna ngaphandle kwezinkundla zokuphakama kusistimu

Ukuvikela lezi zimfushane ziyimpendulo ebalulekile ukufika emaphakathini okuphelele nokusebenza kahle ngeminyaka engaphezulu.

Isiphetho

Ukubala inkundla yomshini wokugcina we-jaw kumaprojekthi yezindlu zokugcina ayikho kuphela umfanekiso osheshayo. Kuyadinga ukuzijabula izindlela zokusebenza kwezinto, iziphakamiso zomshini, nezimo zokusebenza kwezinsuku. Ngokusebenzisa izifactor zokulungiswa futhi ngokuxhumana kwezinsuku zonke, abasebenzi bezindlu zokugcina bangafika emaphakathini amanani akhethekile nokubalwa kwezinhlelo zokusebenza.

Ngeminyaka eyingu-30 yokufunda ngokusebenza kwezinhlelo zokugcina, ukwenza izinhlelo zokusebenza zeprojekthi, nokunakekela izinhlelo zokugcina ezintsha, i-Zhongyu Dingli ibuyisepheka imiprojekthi yezindlu zokugcina ngokwesibonelo esihle, ukukhetha izinhlelo zokusebenza ezinconywa, nokunikeza izinhlelo zokusebenza zonke ezinconywa ukuthuthukisa ukusebenza kanye nokusebenza kahle.
