Abstract:
The invention provides, inter alia, a method for producing granules from a powder, characterized in that compaction force is applied to the powder to produce a compacted mass comprising a mixture of fine particles and granules and separating and removing fine particles and/or small granules from the other granules by entraining the fine particles and/or small granules in a gas stream. Also provided are apparatus for use in the process and tablets formed by compression of the resultant granules.
