| Abstract: | This article introduced two kinds of granulating technologies abroad,namely rolling method and spray method. Meanwhile, this article studied the characteristics of granulated metal powders. The test analysis indicated that the flow rate of granulated metal powders is increased greatly and the bulk density of granulated metal powders is decreased. The pattern of granulated metal powders is also observed through SEM (Scanning Electron Microscope). This article analysed the application of granulated metal powders in making diamond tools, and indicated that the granulated metal powders are specially applied to automatic production of volume filling cold pressing of multi-layer segment. The granulation of metal powders can effectively improve the homogeneous distribution of diamond particles in bond metal powders. |
