The separator, to ensure safety for fuze, has many different shapes, such as a slider, rotating disc, and rotating ball. The ball rotor separator has a compact and simple structure. Thus, it is suitable for use with small-sized fuzes with high rotation speeds. In this article, the author has presented a mechanical model for an object rotating around a fixed point (geometric center of the separator), established a system of differential equations describing the motion of objects, and calculated and determined operating time for design research and testing.
