An apparatus is described which will measure the flow of powder through a moving orifice (die). It is shown that this type of flow, denoted dynamic flow, differs in some respects from static flow, i.e. flow through a stationary orifice. In other respects, e.g. the relation of flow to orifice diameter, the relations found in dynamic flow are similar to the ones reported for static flow. The results are treated in such a fashion that extrapolations to speeds encountered in high speed tablet presses can be made. |
