ABSTRACT:
This invention provides an apparatus for the preparation of dry-medicament granulation. The apparatus comprises an enclosed-circular mixing chamber containing mixing means with a separate air inlet means and air outlet means, both of which are in flow communication with the chamber. The air outlet means is provided with a collecting bag for collecting the dry-fine particles of the medicament granulation and is equipped with a vibrator for returning them to the mixing chamber. The apparatus provides a means for a one step preparation in a batch process of medicament granulations, whereby the granulations may be directly compressed into solid-dosage forms without further processing.
