That is, the time required for 50g powder to flow out of the standard flow rate funnel with the specified aperture, in s/50g, referred to as flow rate. flow ability is measured by funnel for measuring loose density. The flow ability of powder is affected by the properties of powder body and particles, the density of particles, the loose density of powders, and the adhesion between particles. Specifically, the powder particle are large, the particle shape is standard, and the proportion of extremely fine powder in the particle size composition is small, so the flow ability will become better. powder oxidation can improve flow ability. When the particle density is constant, the relative density increases, and the flow ability increases. The adsorption of water, gas on the particle surface or the addition of forming agent will reduce the powder flowability.
