Аннотация
Ways to improve the efficiency with which materials are pulverized in impact centrifugal mills as well as ways of preventing wear of the blades are proposed. The problem is solved using equations that describe the motion of particles on the surface of the rotor in a polar coordinate system. It is discovered that the rate of impact of the particles against a blade increases linearly with increasing angular velocity. The angle of attack and radius of contact of a particle with the blade are independent of this velocity, though they are substantially affected by the initial position of the particles. The nature of the variation of the rate of impact and the angle of attack is determined, based on which possible wear of the blades may be predicted and measures taken to reduce wear.
