29/04/2011· Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Ball milling is suggested as a novel method for enhancing filler dispersion in different matrices that is environmentally and economically sustainable . It is a solid-state mixing of powders, usually performed with ball mills, which enables intimate mixing of the constituents through repetitive plastic deformation. By applying
