Isici esiphezulu soketsheziumshini wokuqhuma isihlabathiilawulwa kahle ukungcola kothuli ngesikhathi se-sandblasting, ithuthukisa indawo yokusebenza ye-sandblastingukusebenza.
Ngokuvamile, uketshezi olupheleleumshini wokuqhuma isihlabathiimvamisa yakhiwa yizinhlelo ezinhlanu, okuyizinhlelo zesakhiwo, amasistimu anikwa amandla ngabezindaba, amapayipi amasistimu, amasistimu wokulawula, nezinhlelo ezisizayo.
Isimiso sokusebenza Uketshezi lwesihlabathi esiwuketshezi ngamandla okuphakelayo esigayo njengegayo, futhi isigayo sokuxuba silethwa esitshalweni sokufafaza ngepompo lokugaya. Umoya ocindezelwe njengamandla okusheshisa okusila, ukusheshisa isibhamu ngepayipi lomoya, ukusheshisa ukugaya komoya ongena ngesibhamu, futhi kujovwa endaweni yomshini ukufeza inhloso yokulindelwa ebusweni bendawo eyenziwe ngomshini.
