Abstract
A method of homogeneously packing powder into a cell is in the process of being developed. In this paper, as a first step in the discusssion of homogeneous powder packing, the powder porosity in the interference region between two points feeding to a cell is experimentally observed and analysed by an X-ray radiograph. Especially, the effect of the powder feeding outlet diameter and powder feeding height on the powder porosity in the interference region are noticed experimentally.
The following results are obtained:
1) For silica sand, dependency of the powder feeding diameter on the powder porosity in the interference region is found to be larger than that of the powder feeding height. The powder porosity shows a lower value than that of the neighbouring region.
2) On the other hand, for alumina powder, the powder porosity in the interfernce region shows an almost constant value, which is larger than that of the neighbouring region, independent of the powder feeding diameter and the powder feeding height.
