Applications of Nano Pulverization
In the pulverization process, there are two types of particle destruction, which are "surface grinding" and "volume grinding". In the process of surface grinding, small pieces break off from a particle surface, which then gradually forms many fine particles. During grinding, the particle sizes often follow a bimodal distribution.
