1.绪言粉体及粉体过程存在于生产的原料、中间体及产品之中。所谓粉体是指大量的固体颗粒的集合体,颗粒之间处于适当的相互作用状态。粉体和通常的固体、液体、气体均有不同,特别是粉体颗粒的形状、大小(粒度和粒径)及大小的分布、表面活性状态及宏观密度等变化幅度极大。因此粉体性状是千差万别的,与粉体关联的诸现象也是极其复杂的,而且粉体性质的波动很大。总之粉体几乎存在于一切工业过程之
1. Introduction Powder and powder processes exist in the production of raw materials, intermediates and products. The so-called powder refers to a large number of solid particles of the aggregate, the particles in the proper interaction between the state. Powder and the usual solid, liquid, gas are different, especially the shape of the powder particles, size (size and particle size) and size distribution, surface activity and macro-density and other changes of great magnitude. Therefore, powder properties vary widely, and the phenomenon associated with the powder is extremely complex, and the great fluctuations in the nature of the powder. In short powder almost exists in all industrial processes
