DENSIFYING OF A BULK PARTICULATE MATERIAL

摘要

A method of densifying a bulk particulate material includes at least partial ly confining the bulk particulate material, and rotating a rotatable member (14 ) submerged under the bulk particulate material about an axis of rotation (16) to cause movement of the material particles essentially towards or away from the axis of rotation, thereby to provide a densified bulk particulate material. The method is particularly suitable for densifying silica fume. Th e invention extends to apparatus for densifying a bulk particulate material.
