ABSTRACT:
Compressible material is compacted into a plug by a device including a housing, solid outer wall, and restricting adjustable portion at an outlet. A root wall is rotated about an axis and conveys the material to be compressed in a channel having solid sidewalls. Without significant extraction of liquid from the material, the material is compressed until discharged in a compacted plug form from the housing outlet. A pneumatic cylinder provides an adjustable force for effecting the compaction adjacent the housing outlet. Examples of compressible materials that may be acted upon in the practice of various industrial processes include wood chips, high consistency paper pulp (cellulose pulp), wax and fibrous waste (for making artificial fireplace logs), and mud and straw (for producing building blocks or bricks).
