Densifying of a bulk particulate material.

摘要

A method of densifying a bulk particulate material includes at least partially confining the bulk particulate material, and mechanically agitating the confined bulk particulate material with at least two elongate rotatable members (14), (15) of which at least one is submerged in the confined bulk particulate material. The rotatable members each have an axis of rotation and include a plurality of axially spaced agitating formations (40) which project outwardly away from their axes of rotation. The rotatable members are transversely spaced.
