The effect of ball size on copper powder particle morphology in dry-type milling was studied using a planetary ball mill. Spherical copper powders were obtained by ball milling at a high rotation speed and with a ball diameter of 1 mm. The experimental results suggest that the particle size and morphology can be controlled by changing the milling conditions during the ball milling. Ball motion
