A ball milling process reduced the jatropha seed biochar size and converted it into micro-nano carbon biofiller. After ball milling, the biochar size was reduced from 1 to 3 mm to the 10 m to 600 nm range, which is around a 90 reduction in size.
Apr 03, 2013 The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating sun disk that rotate in the opposite direction around the disk centre. Because of this, the samples are quickly and effectively comminuted by impact, frictional and shear forces resulting from ball-to-wall and ball-to-ball collisions.
