Summary: Amatshe egranite anga setshenziswa ukwenza imbewu nengqayi ngokuhambisana nemigomo ehlukene yamatshe. 1-2, 2-4, no-4-8 yizimiso ezivamile zamatshe. I-China...

Amaqhwaqhwaba e-granite angasetshenziswa ukwenza umthunzi kanye neconcreti ngokuvumelana nezindinganiso ezahlukene zamaqhwaqhwaba. Izindinganiso ezivamile ziyi-1-2, 2-4, kanye ne-4-8. Ukwakhiwa kwezinsizakalo eTshayina akuyona into eyingqayizivele, futhi isikhangiso somtlambi wamaqhwaqhwaba e-granite elizweni lihlala livuthiwe, okwenze ibe yisici esikhulu esenza umkhiqizo wezixazululo ze-granite eTshayina ukukhula.

Igranite gravel yitshe eliphezulu kakhulu lokwakha ngokuvamile lisetshenziswa. Lokhu kungaba ngenxa yomumo onzima wegranite, okunzima ukuthi lichithwe yi-asidi noma i-alkali noma yindawo yomoya. Lugcwele izinsiza zegranite futhi luhanjiswa kabanzi. China inezinga elingu-9% lendawo (cishe ama-800,000 okwemitha km). Zonke i-granite, futhi i-granite isetshenziswa kabanzi emigwaqweni emikhulu, emabhasi, ezifundeni eziphezulu zokwakha, nasekuthuthukisweni kwezindlu.

Okwamanje, inqubo yokuhlava ikhonkco yasekhaya nesisebenza sohlelo lokukhiqiza ikhonkco lesimanje segranite sekhono sezobuchwepheshe sekhonkco lokukhiqiza legranite sekuyiminyaka eminingi sekuphumelela ngokuphelele. I-Shanghai Shibang Sand and Stone Project Department: Nginohlelo lokukhiqiza lokukhiqiza okuningi kwegranite e-China. Inqubo yokuhlava ikhonkco legranite ingajwayele ukusebenzisa inqubo yokuhlava ngokuphindaphindiwe kwamaqoqo amabili. Isigaba sokuqala sikhetha umshini wokugaya ophiko. Isigaba sesibili ukhetho lwe-Isithuthutha sezinto ezinkulu . Ngokuqinisekileyo, isikrini esivuthayo ngokujikeleza singasetshenziswa ukuhlukanisa amatshe angama-1–2, 2–4, kanye na-4–8 cm (noma mm) ukuhlangabezana nezidingo ezihlukahlukene zokwakha.

Ukukhetha kwe- Isithuthutha sezinto ezinkulu kubaluleke kakhulu. I-Isithuthutha sezinto ezinkulu iveza ukusebenza okuhle, izinga eliphezulu lokubilisa nokusebenza okukhulu kwemveliso. Ukukhetha umbhobho wokuthinta kubaluleke kakhulu, ngoba umbhobho wokuthinta uwumphako wempahla olimaza okudingeka ukugcwaliswa njalo. Izingxenye zokugqoka zomshini wokugabha zithinta ngqo izindleko zokulungisa u-impactor esikhathini esizayo. Kunconywa ukukhetha i-Shanghai Shibang, umkhiqizi odumile wasekhaya wezingxenye zokugqoka ezingangeni emhlambini. Izingxenye zayo ezivikeleka ekuqhelweni njengomumo wokuzungeza, umbhobho wokuthinta, umbhobho wokugabha, ithebhu yemlomo nebhodwe lokufaka sekunqamuleuthiwe futhi kuthole udumo oluhle.

Ngaphandle kokukhiqiza i-gridhi yesihlabathi negravel, kukhona imigqa yokukhiqiza inqwaba yesihlabathi negravel esetshenziswa ngezinto ezahlukene, njengezikwele zosobizi, i-limestone, ibluestone, kanye nemigqa yokukhiqiza ithumba, ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene wokwakha. Ngokwesibonelo, ukwakha izakhiwo eziyisisekelo kungasebenzisa i-limestone enobunzima obuphansi uma kuqhathaniswa nokuhlangabezana nemfuneko; kuyilapho amaphrojekthi wezindlela zokuhamba nezitimela ezisheshayo adinga inqwaba yesihlabathi nosobizi obunzima. Njengoba izakhiwo zezinto ezibonakalayo zihlukene, izinqubo zokukhiqiza ezihambisanayo kanye nezinhlelo zemishini nazo ziyahlukana. Umkhiqizi omkhulu wekhontrakthi ye-line ye-sandstone e-China, i-Shanghai Shibang Engineering Sand and Stone Project Department, uneminyaka eminingi yokuhlangenwe nakho okujabulisayo ekukhiqizeni i-crushing yezinto ezahlukahlukene. Isethulo semigqa yokukhiqiza amathumba eshibhile futhi esizwakalayo singahlelwa ngokususelwa usayizi we site kanye nesabelomali semali yokutshala. umshini.
