    Effect Of Ballmilling Process Parameters On Mechanical

    Nov 01, 2021 Importance of the ball-milling process parameters on the basis F ratio value from the ANOVA showed that ball-milling time contributed most, followed by the BPR and ball-milling speed. Optimum ball-milling parameters were found to be BPR of about 5, BMS of about 178 r.p.m and BMT of about 93 h.
