Pneumatic Waste Extraction Systems

Advances in high speed finishing and converting equipment has lead to the need for continuous extraction of waste materials to improve production efficiencies, increase floor space, increase profit on recycled materials, and reduce materials handling activities.

Waste extraction technology is crucial for the efficient management of waste materials in the print, paper, corrugated, carton, board, and can industries. Waste extraction systems are designed to entrain waste materials at source, chopping if necessary, and conveying to a centralised collection point, using air as the conveying medium. The main components of a waste extraction system include:

• Purpose designed extraction hoods, feeders, or belt conveyors
• System of high-level, heavy gauge ductwork for material conveying
• Chopper fans for airflow generation and breaking down of waste materials
• Air separator to separate waste materials from the conveying air stream
• Compactor or baler unit for waste collection and compression
• Rotary airlocks to prevent pressurisation of collection unit
• Filtration plant for the filtering of dusts from the conveying air stream
• Air recirculation system for recovery of heat back into the facility
• Briquetter for compaction of filtered dusts
