  • Method and apparatus for compacting powders
    Patent number: 9180641
    Abstract: An apparatus for compacting a powder includes a feed section (20), a compaction section (21), a discharge section (22), and a conveyor belt (103) extending through the feed, compaction, and discharge sections to convey powder through those sections. The feed section receives an incoming powder onto the conveyor belt. The compaction section compresses the incoming powder on the conveyor belt between two plates (8, 9) to provide a compacted powder. The top plate (8) may be pressed downward toward the bottom plate (9), the bottom plate may be pressed upward toward the top plate, or both. The discharge section receives the compacted powder from the compaction section on the conveyor belt. End plates (16) and side plates (11) confine the incoming powder during compaction.

  • Apparatus for compacting powders
    Patent number: 8641980
    Abstract: Fluffy powders, such as calcined kaolin clays or air floated clays, can be compacted using a process which comprises applying increasing amounts of pressure to a powder moving through a confinement area. The compacted product has an improved bulk density and improved wet out and slurry incorporation times as compared to the non-compacted starting material feed.

  • Process for compacting calcined kaolin clay
    Patent number: 6761763
    Abstract: Calcined kaolin clay having a high bulk density, improved wet out and slurry incorporation times is produced by using pressure to compact the clay. Other properties of the compacted clay are improved or equivalent to the non-compacted starting calcined clay material.
