We performed the phenomenological calculation of the distribution function of numerous particles which are in the process of fine exfoliating disintegration. As is well known, the fine disintegration method is one of the most important methods to get fine powders of various material, and so the precise analysis of this mechanism is interesting not only as a problem of physics but also from the industrial point of view. We confined our problem within the phenomenological theory because of the lack of knowledge upon the microscopic nature of the fine disintegration on various materials such as metals. The present result may be expressed as follows : 1. The general distribution function of particles can be derived as a function of time and mass of particles. 2. The narrowing or broadening of distribution function which were observed experimentally can be explained respectively as the special stage of disintegration process. 3. The physical characters of materials such as brittleness toughness and elasticity have no serious effect on the shape of distribution function but merely affect the velocity of disintegration. 4. Disintegration process by Bond's method (useful method for making the sphere of solid) is analized from the phenomenological point of view.
