[Studies relationship between powder characteristic of kinds of granules and their hygroscopicity].
OBJECTIVE
To choose the granuling way for preparing granules that had low moisture-absorption characteristics.


METHODS
Granules were prepared by five ways, for studying the relationship between characteristics of powder and hygroscopicity were determined.


RESULTS
The prepared ways of granuling that had low hygroscopicity were dry granuling and secondary swinging granuling.


CONCLUSIONS
The hygroscopicity of granules can be explained by characteristics of powder, which are made in different granuling ways. The prepared ways of granuling that have low hygroscopicity are dry granuling and secondary swinging granuling.
