PPT-FLOW OF POWDERS

Pharmaceutical powders may be classified as freeflowing or cohesive nonfree flowing Flow properties are significantly affected by changes in particle size density shape electrostatic charge and adsorbed moisture which may arise from processing or formulation. In particular the development of fine ceramic powders with unusual and superior properties will be of great in terest The principal driving force is essentially one of tec hnical and economical advantage th at can be achieved through the use of thes Terrick. .

While there are many methods of performing this task the best approach is usually dictated by the hazards associated POWDERS.
