Isiphetho:Amaqoqo anobukhulu obungaphansi kuka-4.75mm, kodwa angabandakanyi amaqoqo alula futhi alinye, akhiqizwa emaqaqweni, emaphongweni noma ezinsalela zomsebenzi wezohwebo emva kokuphumela.
Izingcezu ezinamazinga okukhulu kwezicucu ezingaphansi kuka-4.75mm, kodwa zingafaki izingcezu ezimuncu nezizimele, ezitholakala emithini, ezitholakalayo noma ezisele zezindleko zezimboni ngemuva kokuthoshwa nokuhlukaniswa ngokomshini ngemuva kokuhlanzwa komhlabathi, okuyaziwa ngokuthi umhlabathi we-mashini. Izingcezu ezinamazinga okukhulu kwezicucu ezingaphansi kuka-75μm kumhlabathi we-mashini zibizwa ngokuthi i-stone powder.
Ingabe i-stone powder kumhlabathi we-mashini inezinzuzo? Indlela yokulawula inani le-stone powder? Nazi impendulo.
Izinhlobo ezine ze-stone powder kumhlabathi we-mashini
Imiqulu ye-khonkrithi yamafutha: Izingcezu ze-khonkrithi azinamathisela kuyo, futhi azinamathisa emhlabathini, futhi zingaqhubeka zizulazula ngaphansi kwemiphumela yemoto nethela.
(2) Iphuthu lephunga: Izicucu zephunga lomatshe zihlanganiswe ngamandla ukuba zenze iphuthu elikhulu lephunga lomatshe, futhi izicucu zihlanganisane futhi zihlanganiswe. Leli hlobo lephuthu lephunga lomatshe liyadida ukukhululwa yi-oyikheli yokukhetha iphunga ejwayelekile ngenxa yesiyonke sezicucu nekhulu lezihlanganiso.
(3) Iphutha le-adhesive: Kukhona izicucu zezitsha ezifakwe endaweni yomhlabathi olukhulu, okuqukethe izingqimba ezinkulu. Uma iphethini yomhlabathi inokukhanya, izicucu zezitsha zithatha kalula ngamandla okusebenza kwezinto ezibonakalayo, futhi uma iphethini yomhlabathi ingaqinile, izicucu zezitsha nomhlabathi zihlangana kahle, okwenza kube nzima ukuwahlukanisa ngezindlela ezijwayelekile zokusebenza kwezinto ezibonakalayo.
(4) Iphutha le-powder: Ngokuvamile kukhona izindawo ezimbili ezitholakala ngokwemvelo noma ezitshalwe ngokomshini ngokubanzi phakathi kwe-tens kuya kwe-hundreds of microns emhlabathini. Lezi zindawo zivame ukugcwaliswa yi-powder eningi yezitsha. Lokhu kuyindlela yokugcina eyiqinile kakhulu yokuxhuma i-powder yezitsha.
Umsebenzi we-powder yezitsha emhlabathini oqeqeshwe ngomshini
1, ukukhishwa kwamanzi
Izifundo zibonise ukuthi i-ettringite eyenziwe ekuqaleni kokukhishwa kwamanzi izoqanjwa i-monosulfur calcium sulfoaluminate esigabeni esilandelayo, okuzothusa amandla okwakha, kodwa ukwengeza i-powder yezitsha elwela i-ca **Note:** Zulu, like many languages, doesn't have a direct equivalent for the technical term "Crevice powder". The translation attempts to convey the meaning. Also, some technical terms are challenging to translate accurately without more context. The translation is a good starting point, but might require further refinement for a precise technical document.
2, umphumela wokugcwalisa
I- powder yesihlabathi samatshe ingagcwalisa izikhala ku-concrete futhi isebenze njengomfakisicelo we-concrete ukukhulisa ubukhulu be-concrete, ngalokho isebenza njengomxube ongasebenzi. Mayelana nezici zendawo encane yezinto zokubopha kanye nokusebenza okungalungile kwe-mixture, kungaxazululwa ngempumelelo ngokusebenzisa i-concrete enoshizi oluphakathi nokuphansi lwezihlabathi ezenziwe ngomshini.
3, ukugcinwa kwamanzi nokwanda kobukhulu
I-concrete ezenziwe ngomshini ihlanganisa i-powder yesihlabathi samatshe, enganciphisa ubungozi bokuhlukanisa nokuphuma kwamanzi ku-mixture ye-concrete. Ngoba i-powder yesihlabathi samatshe ingakwazi ukumunca amanzi ku-concrete, iyakwazi
Ngenkathi umthwalo wesihlabathi oqeqeshwe ngamakhulu udlalela indima ebalulekile emkhakheni wesihlabathi sekhonkrithi esenziwe yimishini, akuyona into eyiqhaza. Ucwaningo luthole ukuthi inani lomthwalo wesihlabathi kufanele libe ngokufanele. Ingxenye eyinhloko yomthwalo wesihlabathi emkhakheni wesihlabathi sekhonkrithi esenziwe yimishini yi-calcium carbonate, kodwa umphumela wokunwebeka akulona okungapheli futhi uqeqeshwe yi-composition yecementi. Uma inani lomthwalo wesihlabathi liphezulu kakhulu, akusiyo into eyiqhaza ekuhlanganiseni kwe-aggregate necementi, ngoba umthwalo wesihlabathi oqeqeshwe ngamakhulu oqondile uzobonakala ecementi noma esiqongweni sohlangothi, ngaleyo ndlela kunciphisa ukusebenza kwekhonkrithi.
Ukuphathwa kwesilinganiso sezinto eziqunyiwe zeqhwa esandleni elenziwe yimishini
Ngekhwalithi yokuhlolisisa kokwakhiwa, ukuze kufinyelelwe esilinganisweni esidingayo sezinto eziqunyiwe zeqhwa, lapha ngezindlela ezimbalwa zokulawula ukulinganisa kwezinto eziqunyiwe zeqhwa:
(1) Indlela yokuhlola ngokomile: Indlela yokuhlola ngokomile isebenziswa eworkshop yokuhlola yesibili, futhi isanti esincane kunama-5mm iqhunyiswa ngqo yimpahla yokuthutha nge-belt, okuthi ekugcinweni kwesanti eliphelele, kunciphisa ukulahlekelwa kwezinto eziqunyiwe zeqhwa. Ekusebenzeni kokuhlola, ingxenye yezinto eziqunyiwe zeqhwa ihlanganiswa emgodini futhi ilahlekelwa, bese i-dust collector i-
(2) Ukukhiqiza okuhlangene kwezindawo ezihlanganisiwe:i-sand making machinekunamikhuba emibili yezindawo ezihlanganisiwe endleleni yokusebenza: i-rock-on-rock kanye ne-rock-on-iron. Isiqubulo sesihlabathi esisuka ekuthuthukisweni kwensimbi ngomkhuba wokucisha i-rock-on-iron kuningi, kodwa ipheti yokuvikela yokunqoba ihlushwa ngokushesha futhi ixabisa okukhulu. Isiqubulo sesihlabathi esisuka ekuthuthukisweni kwensimbi ngomkhuba wokucisha i-rock-on-rock kuncane futhi ixabisa kancane. Ukuxuba lezi zindlela zokucisha kungalawula kahle isiqubulo sesihlabathi.
(3) Ukukhiqiza okuhlangene: Ukuhlanganisa umshini wokwenza isihlahla kanye nomshini we-rod mill emisebeni yokukhiqiza ukuze kwandiseswe isihlahla
(4) Indlela yokukhiqiza eomileyo: Iprosesi eyinhloko yokukhiqiza i-santi yemfuyo ngendlela eomileyo ukuthi ama-aggregate ngemva kokucwiliswa nokwenziwa kwe-santi, athunyelwe ngqo kwisikrini esijikijwayo, lapho okuhlukileyo okukhulu kunama-5mm kucwelwa khona, futhi i-santi encane kunama-5mm iqhutshelwa ngqo ebini le-santi egediwe nge-belt conveyor, okuholela ekunciphiseni ukulahlekelwa kwe-stone powder.
(5) Ukubuyiselwa kwe-powder yezitsha: Sebenzisa izixazululo zokubuyisela i-powder yezitsha ukuze kubuyiselwe i-powder yezitsha elahlekile emsebenzini wokusiba, ukopha, nokulungisa okomile, bese uhlanganisa i-powder yezitsha ebuyiswe ngokulinganiselayo ebhokisini le-sand egqokile.
Ngenxa yokusebenzisa izindlela ezishiwo ngenhla, inani le-powder yezitsha emvelweni ye-sand lingalawulwa ku-10-15%.
