IMPROVEMENTS IN POWDER COMPACTION

摘要

An agitator device for an apparatus for enrobing powders. The agitator device comprises a rotatable agitator (56) having an axis of rotation and housed in a chamber defining a flow path for powders that is transverse to that axis of rotation. The agitator (56) comprises at least one agitator member (60, 60E) arranged such that, in use, rotation of the agitator causes the at least one agitator member to impart reciprocating forces to powder passing along the flow path. The reciprocating forces act in the general direction of the axis of rotation.
