Document Type and Number:
Japanese Patent JPH06502686
Kind Code:
A
Abstract:
A process for the surface treatment of individual particles of a pulverulent material to improve the surface properties thereof. The process includes a plasma-generating apparatus for generating a plasma in a plasmagenerator while supplying an inert gas at a high drift velocity into the generator to form a low temperature plasma flame which is directed into a low pressure zone. Subsequently, the pulverulent material is injected into the high velocity inert gas or into the base of the plasma flame to disintegrate any particle aggregate present in the material. The low temperature plasma acts on the surface of each individual particle to improve the properties thereof. The treated particles can then be recovered from the zone.
