| Abstract: | The structure of ultracritical rotation speed mill has been introduced and the motion law of the balls and the ores in the mill has been analysed and studied. The motion locus expression and the highest crashing velocity of the balls have been deduced when the balls move along parabola locus. The results show that the parabola locus of the balls is mainly determined by the place of the low end of the guidance arc plate and the highest crashing velocity of the balls is determined by the rotation speed and the diameter of the mill. |
