摘要：The pulverization of single particle natural rubber ball was studied based on the cryogenic impact experiments.Through investigation of the size distribution of the crushed product, the influence of impact speed, grinding temperature, initial particle size and impact angle on the particle fragmentation were studied.It is found that the particle''s impact speed and grinding temperature influence the size distribution of crushed natural rubber ball most;when the impact angle ranges from 0° to 45°, the impact angle influences the size distribution non-significantly;The percentage of small size particles in the crushed product increases with the decrease of the initial particle size.
