Abstract
A system is provided for pelletizing particulate raw matter having a first density, and thereafter subjecting the pellets to a milling process to obtain a powdered form of the particulate. During pelletizing steam can be added. The resulting powder is denser, or more granular or has better flow with less dust than the pre-pelletized particulate matter having the first density. The powderized particulate has applications for pharmaceutical, nutritional and herbal end products.
