Chitsulo chosapanga dzimbiri grit ndi chitsulo chosapanga dzimbiri angular tinthu. Itha kugwiritsidwa ntchito m'malo mwamitundu yambiri yamchere komanso yopanda zitsulo, monga alumina, silicon carbide, mchenga wa quartz, mkanda wagalasi, etc.
Chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito makamaka kuyeretsa pamwamba, kuchotsa utoto ndi kutsitsa zitsulo zopanda chitsulo ndi zitsulo zosapanga dzimbiri, kupanga roughness pamwamba yunifolomu, motero makamaka oyenera pretreatment pamwamba pamaso zokutira. Poyerekeza ndi ma abrasives osapanga zitsulo, grit yachitsulo chosapanga dzimbiri imathandizira kuchepetsa ndalama zogwirira ntchito komanso kutulutsa fumbi komanso kukonza malo ogwirira ntchito.
Grit yachitsulo chosapanga dzimbiri imakhala ndi moyo wautali wautumiki komanso kuphulika kwamphamvu, kufewetsa njira yophulitsira, kupulumutsa mtengo, kukwaniritsa kuphulika kosasunthika, kuuma kofanana ndi mawonekedwe.
