Abstract: The characterization of materials is a pacing factor to impor tantfeasibility in the process of pneumatic conveying. Realizing the pneu m atic conveying technique of powder is based on researches of powder’s characteristics.T he fundam entalcharacteristics of powder to assess pneu matic conveying and correlated parameter were analyzed roundly. It was found that the particle size, size distribution and shape were key parame ters to assess whether the materials would be conveying in dense phase flow. Other characteristics were related with these characteristics. Some classifications of powder’s pneumatic conveying characteristics used w idely were introduced and commented. The direction of research was presented.
