Summary: Ekuhleleni kwesitimela sesitimela esikhungweni, ukuhlela kwezinto eziphuma kukho kufanele kube yisikhawu kubukhali bokuhlanganiswa kwe-asphalt, futhi futhi kusho isimo esiyisisekelo esithinta ikhwalithi yokwakha...

Ekwakheni emgwaqweni wezindlela ezisheshayo, ukuhlukaniswa kwezinto zokuhlanganisa kuyisihluthulelo esibalulekile ukuqinisekisa izinga lezingxenye ze-asphalt, futhi futhi yisici esiyisisekelo sokuphatha ikhwalithi yokwakha. Lesi sihloko sabelana ngomgomo wenqubo, ubuchwepheshe obubalulekile, ukukodwa kwemishini, nezin points zokusebenza zesihlabathi nosayizi wezinto zokuhlanganisa.

Imiphumela yokusebenza

(1) Khetha umthombo wempahla yomgodi bese ukhulula umhlabathi oqoshwe phakathi, izitshalo ezimhlophe, njll., ukuqinisekisa ukuthi impahla esisisekelo ifanelekela izidingo;

(2) Hlela indawo yokusebenza ngokuhlakanipha bese ubeka ama-crusher nama-vibrating screen;

(3) Qinisekisa izinga lokukhiqiza kanye nokhutshwa kwemishini yokucrusher ngokuhambisana nezindinganiso nemikhuba yempahla ngayinye;

(4) Ngokuhambisana nezibalo zokuhlola kanye nokuhlolwa kabusha, qinisekisa uhlobo lwescreen, ubukhulu bezinhlayiya zescreen, indawo yokubeka i-screen, isimo sokuhlelwa kwe-mesh kanye nobukhulu ukuze kuhlangabezane nezidingo.

(5) Ukuqhaqhwa kwezinto ezibonakalayo, ukwenza izivivinyo njalo, nokulungisa nokugcinwa kwemishini yokukhiqiza ngokwesimo sangempela.

Ikhono elibalulekile lokukhiqiza ama-aggregate

Izindlela ezisemqoka zenkqubo yokukhiqiza i-aggregate zihlanganisa kakhulu izinto ezintathu: ukuhamba kwenqubo, ukulungiselela amasihlabahla ashintsha isithombe, nokuhlolwa kwezigaba zemishini. Lezi zindlela ezintathu ezisemqoka futhi yizona eziyinhloko ezithinta ikhwalithi yokulinganisa kwezinto zegolide. Ukulawulwa kwenqubo okuhambisana nakho kuhlaziywa kanje.

(1)Ukucaciswa kwekhwalithi yokushicilela

Kukhona izinhlobo ezintathu zezindlela zokusebenza ezivame ukusetshenziswa ekukhiqizeni ama-aggregate emgwaqweni oqhubekayo:

  • one is two-stage crushing: jaw crusher → impact or cone crusher→ vibrating screen;
  • the second is three-stage crushing: jaw crusher → impact, hammer or cone crusher → impact or hammer crusher (particle shaping) →vibrating screen;
  • third is four-stage crushing: jaw crusher → impact, hammer or cone crusher → impact or hammer crusher (particle shaping) → impact crusher → vibrating screen.

(2) Ukuqondisa uhlobo lomaciki

Kukhona izinhlobo eziningi zamaciki wemithombo, ezisetshenziswa kakhulu yi-jaw crusher, i-cone crusher noma i-hammer crusher, i-impact crusher, njll. Ngalomaciki ngalinye linezinzuzo zalo, okuqondisiwe ngokusekelwe ezidingweni zolwimi lwempahla ephathelene nomsebenzi, isimo somthombo kanye nezici zokusebenza endaweni.

Ngesikhathi esifanayo, ukuze lawulwe ukuba khona kwe-dust ezimvelweni ezithuthukisiwe ngesikhathi sokuthuthukisa izinto eziqinile, okufanele kongezwe yikho isixazululo se-induced air dust removal emsebenzini noma esimvelweni esiphelile.

(3) Uhlobo lwesikrini

Izinhlobo ezivame ukusetshenziswa zesikrini ziyisikrini esijikijaka, isikrini esibuthwa kanye nesisikrini esimnyama, zonke lezi zinethonya elihle lokukrinja. Ngesikhathi sikhetha uhlobo lwesikrini, kufanele sizicabangele izimo zendawo.

Ngemva kokubona uhlobo lwesikrini, kudingeka kuqondile ukulinganisa isivinini sokujikeleza kwesikrini esijikijaka kanye nomqondo wokunamathisela kwesikrini ngokuvumelana nenani lokukhishwa okubekwe. Umqondo wokunamathisela oqine kanye nesisivinini esikhulu sokujikeleza kwesikrini, okukhulu ukukhishwa kwezinto ezihlanganisiwe, futhi okuphambene nalokho.

(4) Ukubonaqaphela ipharamitha ngayinye ye-vibrating screen

Ukuvulwa kwesihlungi sekhasi kusethwa ngokuhambisana nezici ze-aggregate, okuvamile kungaba ngu-2-5 mm kunukhulu kwenani lezinkuni ezenzakalelayo le-aggregate elifunwa yisakhiwo. Ukusetha okukhethekile kufanele luhlelwe kahle ngokuhambisana ubukhulu, okuqukethwe kwe-aggregate kanye nejubane lokushukuma kwesihlungi esiphakeme. Uma i-aggregate ingamashizi futhi okuqukethwe kukhulu, kufanele wandise ngokufanele ukuvulwa kwesihlungi; uma i-engeli yokushukuma kukhulu, kufanele wandise ngokufanele ukuvulwa kwesihlungi. Ngokuqhathanisa, nciphisa ukuvulwa kwesihlungi sekhasi.

Ngasikhathi esifanayo, ubude benethi yesikrini kufanele sibekwe ngokweqiniso nasekuqukeleni kwengqayizivele ngayinye ye-aggregate. Okokuqala, thatha ingxenye ye-aggregate ku-conveyor belt yesigaba sokuqala (okuyiyo i-conveyor belt yokuqala emva kokubhidliza), uyihlunge ukuze unqume okuqukethwe nosayizi wenqayizivele ngayinye ye-aggregate. Uma okuqukethwe kwe-grade ethile ye-aggregate kuphezulu, khulisa ubude benethi yesikrini ngokufanele; ama-aggregate amancane ngokhaphazi nawo kumele aminywe ubude benethi yesikrini. Ngesinye isikhathi, ukuba mfushane ubude benethi yesikrini. Indlela yokumisa inethi yesikrini ukuthi yamukele amascreen amancane eduze nokungenisa i-aggregate futhi ahlele izinkanda zesikrini ukusuka kumancane ukuya kokukhulu. Bese, inani lezakhiwo zesikrini kufanele linqunywe ngokutshalwa kwemali ukukhiqiza.

Izakhiwo zokugcina ezizalwa ngezakhiwo ezingenhla azikhohlwa ngumthelela ofakthali abalandelayo, kodwa zihlobene futhi zihlanganisa. Ngakho-ke, ekusebenzeni kokuhlela, kuyadingeka ukuba kube nokuhlelwa okuningi okuhlangene. Ngokwezimo zokuhlolwa kwangempela, omunye noma amaningi ama-parameter ahlolwa kuze kube yilapho izakhiwo ezifanele zikhona.

Ukubuyekezwa kwezinhlelo

Izakhiwo ezizalwa azikhohlwa kuphela ngokuhlolwa kwesikrini esijikijwayo, kodwa futhi zihlobene kakhulu nenkambiso ye-mechanical yokucisha umonakalo.

Kunezindawo ezimbili zokuthinta ezincishiseni zokuthinta ukuze zenze amaqembu amabili okucisha. Ukulungisa inqola yensimbi kungashintsha isikhala phakathi kweplate yokuthinta nenqola yokuthinta, ngaleyo ndlela kwashintsha izinga lobungako bemicu evelayo. Ngokuvamile, ipuleti yokuqala yokuthinta inesiqephu esikhulu njengesigaba sokuqhekeza okukhulu; ipuleti yesibili yokuthinta inesiqephu esincane njengesigaba sokuqhekeza okulinganayo nokulinganiselwe.

Lungisa ibanga phakathi kwezindawo ezimbili zomthelela ngaphambi kokukhiqiza ngokusemthethweni, ukuze ama-aggregate akhiqizwayo ahambisane nesilinganiso esinqunyiwe sokuphumelela kokudlula usayizi weqoqo.

Ngokuvamile, lapho kusetshenziswa izendlalelo eziphakathi nezansi zokuqukethwe kwe-aggregate ye-epresiway, indawo phakathi kwephutha lokuthinta lokuqala nekhelisi lokushaya liyashintshwa laba yimitha engama-35mm, futhi indawo phakathi kwephutha lokuthinta kwesibili nekhelisi lokushaya iyashintshwa ibe yimitha engama-25mm; lapho kusetshenziswa izendlalelo eziphezulu ze-aggregate ye-epresiway, indawo phakathi kwephutha lokuthinta lokuqala nekhelisi lokushaya iyimitha engama-30mm, futhi indawo phakathi kwephutha lokuthinta kwesibili nekhelisi lokushaya iyimitha engama-20mm.

Ezinye izimboni zokucwilisa amaqhwa nokususa amatshe zilungisa umkhumbi phakathi kwe-impact plate ne-blow bar ukuze khulisa amathuba okukhishwa kwamatye ahlakazekile.

Izindawo zokusebenza

(1) Hlola imvelaphi yezinto, futhi ubambe umthombo wekhwalithi kanye nesikhathi sokuhambisa nokunye ulwazi.

(2) Indawo iqinisiwe, futhi amabhamuza okucutwa komfula asethelwe ukuphatha ukungcola okwesibili kwama-aggregates.

(3)Uma uhlela ibhithi yokugcina yomshini wokugaya ukhwezi kanye nebhethi lokugcina endaweni, kufanele kubhekwe ngokuphelele ibanga lokuhamba kwe-aggregate yomkhiqizo iye endaweni, futhi kufanele kuphaketheke ngokufanele ibhithi lokugcina ngokuphakathi kokukhipha ngakunye kwe-aggregate eyodwa.

(4) Ngokohlelo olwakhiwe, lungisa ngobunono usayizi wenethi kanye nobude besikrini ukuze kuqinisekiswe ukuthi i-aggregate ngayinye yosayizi oyedwa ihlangabezana nezidingo zemfuneko.

(5) Ukuze kuncishwe uthuli futhi kuphothulwe ukuhlukaniswa, faka yomisa umoya wokuhlanza uthuli, futhi ungeze inani elilungile lamanzi uma kudingeka.

(6) Ngesikhathi sokukhiqiza ngesikhathi sezulu elivayo, valela isikrini esiqothulayo kahle ukuvimbela ukungahlukanisi okuphelele ngesikhathi sokuphahlazeka.

(7) Ama-aggregates aphelile azobekwa ungqimba noma afakwe isigxobo ukuze agcinwe emanzi, ukuze kugcinwe amandla ekuqhubekeleni nokucutshungulwa okuzayo.

(8) Ngesikhathi sokwenza umsebenzi we-aggregate, ukuphathwa kokukhiqiza kufanele kwenziwe ngokuvumelana nokukhiqiza ngesikhathi sokuhlolwa, ukuze kuqinisekiswe izindinganiso ezimele ze-aggregate eyenziwe.
