Abstract
When compacting particulate material, such as granular or powdery material, the same is fed to a first section which determines the compaction degree. In a second section, the weight/volume ratio is further increased so that it determines further the ultimate compaction degree. Optionally the compaction degree is controlled a third time within a third section which is normally the final section. In order to influence and to control the compaction degree at least in the first and second sections, energy can be absorbed by means of separate drives within these sections.
