Effect of size of a tubular mold on the density of a loosely poured powder mass

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

An analytical expression, verified by experiment, has been obtained for calculating the maximum density of a powder mass composed of single-fraction spherical particles loosely poured into a tubular mold. Curves of maximum density vs wall thickness of tubular parts have been constructed for the range of values of k=(Ro-Ri)/d which are usually employed in the manufacture of standard filter elements. It has been established that with increasing k the density at first grows up to a certain limit, but beyond this point no significant increase in density is observed. It has been demonstrated by experiment that, for a powder poured into a tubular mold at an optimum rate, the maximum density of the powder mass is independent of mold height.
