Abstract
Abstract Apparatus for collecting waste material, such as dirt and trash from a cotton gin or similar source, and compacting the material to prevent atmospheric pollution. An air stream carrying the waste material is injected into a separation chamber, which contains deflection means to deflect the larger waste particles to a compacting screw conveyor. The air, and suspended fine particles, are extracted from the chamber by a blower, which reduces back pressure in the chamber and minimizes power requirements. The fine particles are collected in a condenser and added to the other compacted material for disposal or other use.
