In thepresentwork,we investigate the destruction efficiency of hexachlorobenzene (HCB) by milling with various reagents in a planetary ball mill under different milling conditions. Under the same conditions of mill rotary rate and charge ratio, the mixture of magnesium powder and aluminum oxide (Mg/Al2O3) was found best in promoting the destruction of HCB, which can be completed destroyed after...

Abstract We have carried out numerical simulation of the flow in jet mill ejector. The features ejector are an annular unit for supplying additional gas form a confuser section at inlet to accelerating tube, as well outlet tube. In course study, we varied length and angle supply. established optimal parameters ejector, which it has been most uniform distribution velocity use scheme under study ...

For smaller mechatronic device, especially for micro Electronic system, a micro machining is a must. However, most investigations on vibration of a mill have been limited to the traditional type mill. In this article, vibration and dynamic characteristics of a micro mill were investigated in this study. The trend towards higher precision manufacturing technology requires producing miniaturized ...
