Isiphetho:Kukhona abaningi abafuna ukufaka imali emashini yokwenza isethwe ngenxa yokuqhubeka kwemboni yezinto ezakhiwayo kule minyaka edlule.</hl>

Kuyadingeka wazi inqubo yokwenza isanti ngaphansi kwesimo sezulu esishisayo sokwenza isanti ngokomshini emkhulu. Njengoba sonke siyayazi, inqubo yokukhiqiza isanti eyenziwe ngokomshini ikakhulukazi ihlanganisa inqubo yomshini oqeqeshwe ngomoya, inqubo yomshini oqeqeshwe ngomoya osemnyama kanye nenqubo yamanzi. Abasebenzisi bangakhiqiza izinhlobo ezahlukene zesanti eyenziwe ngokomshini ngokuya ngezinqubo ezahlukene zokukhiqiza. Kodwa kusekhona abaningi abangaziqondi lezi zinqubo ezintathu zokwenza isanti, ngakho-ke, ngezansi sizokwethula eminye imibuzo mayelana nalezi zinqubo.

Yiziphi izinzuzo zokwenza isanti ngendlela yomkhuba oqondisayo?

  • Umquketho wamanzi wesihlabathi esenziwe ngokukhiqiza okuyisiqalo ngokomkhuba oqeqeshwe ngokomkhuba uvamise ukuba ngaphansi kwe-2%, i-mortar yempahla noma i-mortar yomkhuba ingasetshenziswa ngqo.
  • Ukuqukethwe kwamanzi e-powder esiqeshini esiphelile kungalawulwa futhi kuphinde kusetshenziswe ngokusebenzisa isistimu eyodwa, futhi ukukhishwa kwe-dust kunganciphisa.
  • Indlela yokukhiqiza i-sand ngokomkhuba oqeqeshwe ngokomkhuba ingasindisa imithombo yamanzi hhayi kuphela amanzi (amanzi amancane noma angaphili), kodwa nezomthombo zemvelo ezinye.
  • Kubalulekile ukuthi abasebenzisi balawule izinhlobo eziningi zokusebenza ngokomkhuba oqeqeshwe ngokomkhuba, okungcono kakhulu ekusebenzeni ukuphathwa okuzenzakalelayo.
  • Umsebenzi wokukhiqiza umlotha omomile awuqondiswa yimiphumela yendawo, ixesha lobusika nobukhulu.

2. Kungani kusetshenziswa kancane inqubo yamanzi?

  • Okokuqala, inqubo yamanzi idinga amanzi amaningi.
  • Ukulinganiselwa kwamanzi emlotheni oqediwe kukhulu, ngakho kudingeka ukuba uhlanzwe.
  • I-modulus yokulinganisa umlotha oqediwe (nginqubo yamanzi) iphezulu, futhi kungase kube khona ukulahlekelwa komlotha omncane ngenqubo yokuhlambulula umlotha, okholela ekuphumeleni okuncane komlotha.
  • Kuzobe khona inani elikhulu le-silt nama-sewage ngenqubo yokukhiqiza umlotha wamanzi, okuyinkinga ngokuthi kuyadlayo ngokomzimba.
  • Izinga lokusebenza kwe-wet process akulona olujwayelekileyo ngesikhathi sezulu elomile, elomile noma elomkhathi.

3. Izici ze-semi-dry sand process

Uma kuqhathaniswa ne-wet sand production process, isanti eliqedwe yi-semi-dry process alisadingi ukucwilwa, ngakho ukusetshenziswa kwamanzi kungaphansi kakhulu kunokwenzeka nge-wet process, ukunciphisa ngokusebenza i-stone powder kanye nokuqukethwe kwamanzi kwesanti eliphelile.

Ixabiso lokusebenza kwesanti semi-dry process liphezulu kunokwenzeka nge-dry sand production process, kodwa linguphansi kunokwenzeka nge-wet sand production process. Ukuqukethwe kwe-stone powder kwesanti eliphelile kanye nezindleko zokusebenza nazo zihlushwa.

4. Ikhwalathi, elomile, elamanzi, i-semi-dry isandla, yini indlela yokukhetha?

(1) Khetha ngokuvumelana nezidingo zokukhiqiza

Okokuqala, abasebenzisi kufanele bakhethe isixhumi esenziwe umshini wokwenza isanti ngokuvumelana nezinto ezifana nemithombo yamanzi yendawo, izidingo zokuba khona kwamanzi, nokuqina kwesanti eyenziwe, kanye nokululama kwempahla yokuqala.

Kucatshangelwa ukuthi abasebenzisi bangakhetha indlela yokukhiqiza isanti esomileyo kuqala, indlela yengxenye-omileyo ingasetshenziswa njengesinqumo sesibili, bese kuthi indlela yamanzi ibe yesinqumo sokugcina.

(2) Izindleko zokukhiqiza

Ekuqondeni izindleko zokufaka izixhumi zensiza yokwenza isanti kanye nezindleko zokusebenzisa isanti nezinsimbi, kanye nobunzima bokwenza izinto ezihlukahlukene.

Ngeminyaka engu-30 yokwenza isithwathwa, i-SBM iye yaziswa imikhuba ephambili yasemzini, iqhuba isikhululo sokwenza isithwathwa esifana ne-VU Tower. Isithwathwa esenziwe yi-VU Sand-making System sinomkhiqizo oqeqeshwe kahle futhi inqubo yokukhiqiza ayikhiqizi i-sludge, amanzi ashiyekile noma uthuli, okuhlangabezana ngokuphelele nezidingo zokukhuseleka kwendawo. Kuyaletha izinzuzo ezinkulu nezithuba zokuthuthuka emikhiqizweni yesithwathwa, ukuxuba okomile, ukuxuba okwengqalasizinda, amapayipi, imikhiqizo yecimenti nakwezinye izakhiwo.
