Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

SYNTHESIS OF BARIUM HEXAFERRITE/IRON OXIDES

XRD results revealed that after 20 hours of milling, nano-composite of BaFe 12 O19 /Fe 3O4/Fe 2O3 was obtained. By extending the milling time to 40 hours, FeO was detected as the dominant crystalline phase with crystallite size of 22 nm. Composite of Fe/FeO/Fe 3O4 was synthesized by controlled heat treatment of the 40 hours milled sample.
