Abstract
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.

A method of densifying a bulk particulate material, the method including
- at least partially confining the bulk particulate material;
- and
- mechanically severely agitating the confined bulk particulate material without significantly fluidising the bulk particulate material and without causing any stable cavities in the bulk particulate material, the agitation being with at least two elongate rotatable members submerged in the confined bulk particulate material, to provide a smaller average particle size and increased BET surface area, the rotatable members each having an axis of rotation and including a plurality of axially spaced agitating formations which project outwardly away from their axes of rotation, and the rotatable members being transversely spaced and arranged one above the other, thereby to densify the bulk particulate material.
