Qhov kev ua tau zoo ntawm lub log abrasive yog txiav txim siab los ntawm nws qhov loj me, uas yog txhais los ntawm tus lej mesh (tus naj npawb ntawm qhov screen qhib ib nti). Qhov no ncaj qha cuam tshuam rau kev ua haujlwm:
** Coarse grit (24-36 mesh): ** Cov khoom loj, sib tsoo ceev tab sis ntxhib nto, haum rau deburring ntxhib qhov chaw los yog ntxhib sib tsoo ntawm welds.
** nruab nrab grit (46-80 mesh): ** Sib npaug efficiency thiab nto tiav; 46 mesh tshem tawm cov cuab yeej cim, thaum 80 mesh yog ze rau kev sib tsoo zoo.
** Fine grit (100 mesh thiab saum toj no): ** Cov khoom zoo, du nto, siv rau kev sib tsoo zoo lossis cov cuab yeej polishing.
Thaum xaiv, xav txog cov khoom siv: Brown fused alumina (siab hardness) feem ntau yog siv rau cov hlau, thaum silicon carbide (tiv thaiv kev kub nyhiab) raug xaiv rau cov hlau tsis yog -.
