Ukuqhunyiswa kwesihlabathi kubizwa nangokuthi ukuvunguza kwesihlabathi kwezinye izindawo. Indima yayo ayikona nje ukususa ukugqwala, kodwa futhi ukususa amafutha. Ukuqhuma kwesihlabathi kungasetshenziswa ngezindlela eziningi, njengokususa ukugqwala ebusweni bengxenye, ukuguqula ingaphezulu lengxenye encane, noma ukuqhuma kwesihlabathi indawo ehlangene yesakhiwo sensimbi ukuze kwandiswe ukungqubuzana kwendawo ehlangene. Ngamafuphi, manje i-sandblasting ibalulekile embonini, i-abrasive esetshenziswa ekuqhumeni isihlabathi sezimboni ngokuvamile i-alumina ensundu. Lokhu kungenxa yokuthi ukusebenza okuqinile kwe-brown corundum, ukuguquguquka okuhle, kufanelekile kumamodeli ahlukahlukene omshini wokuqhumisa isihlabathi. Kodwa-ke, i-alumina ensundu ehlanganisiwe izoba nezinkinga ezithile ohlelweni lokuqhunyiswa kwesihlabathi.
1. I-nozzle yomshini wokuqhumisa isihlabathi ayikhiqizi isihlabathi: isizathu esiyinhloko ukuthi kunezidumbu zangaphandle ku-nozzle, okuholela ekuvinjweni kwe-nozzle. Uma usebenzisa i-brown corundum abrasive ye-sandblasting, kuyadingeka ukuhlanza umshini we-sandblasting njalo, ngenxa yomthamo omncane we-sandblasting, uthuli kanye nezinhlayiya ezincane eziphukile ezithwalayo zizovinjelwa kwezinye izikhala, ezithinta ukusetshenziswa komshini we-sandblasting.
2. Amandla omthelela womshini we-sandblasting awanele: uma amandla omthelela we-sandblasting enganele, i-corundum ensundu ihlale inamandla okugaya futhi ayikwazi ukususa izindawo zokugqwala kahle. Isizathu esiyinhloko salesi sigameko ukuthi ukucindezela komshini wokuqhumisa isihlabathi ngokwawo akwanele, okuholela ekunciphiseni ukushaywa kwesihlabathi.
Ngaphezu kwalokho, ubukhulu be-nozzle bunomthelela othile ekucindezelweni, okungukuthi, i-nozzle encane, ingcindezi enkulu, kodwa i-nozzle akufanele ibe mncane kakhulu, ngoba incane kakhulu izothinta ukusebenza kahle kokuqhuma kwesihlabathi. Eqinisweni, ukuze kutholwe umphumela omuhle we-sandblasting, kuyadingeka ukuthi opharetha abambe kahle inqubo yokusebenza kwe-sandblasting futhi abe nokuqonda okwanele kwemingcele ye-sandblasting. Ngamafuphi, umphumela wokuqhunyiswa kwesihlabathi uncike kwikhwalithi yomkhiqizo, ngakolunye uhlangothi kuncike kubuchwepheshe bomqhubi.
