To obtain the outcome precisely, the study varied working volume under constant other processing parameters i.e., ball-to-rice straw ash, milling speedrotation, temperature, ball size in the batch-typed conventional ball-milling process. The results showed that the ball-milling process is effective to reduce particle sizes to several ...

Surface coating copper powder with carbon

The results revealed that CNT coating of a metal powder surface can be achieved with a dry ball milling process using both the TBM and SBM. The most important factor in CNT particle coating based on a metal matrix, is subjecting the sample to low grinding ball impact force over a longer time period, rather than greater force over a short time.
