Flow index of powder
WebPowder which the flow ability stays stable under the stress effect. This powder is not affected by the rotating speed (electrolytic copper). So, at each rotating speed, as high is the flow angle, as high is the adherence behaviour (static component of the flow). Figure 4: Cohesive indexes versus the rotating speed stress for different metal powders WebThe flowability characteristic of a powder is directly related to both the physical properties of the material itself, as well as the specific processing conditions in the handling system. Consequently, for such a complex …
