摘要： The present disclosure relates to the treatment of streams derived from construction and/or demolition (C&D) debris, such as C&D fines streams, asphalt shingles, drywall, or wood. The process can include a kinetic pulverization stage through a kinetic pulverizer where the frangible materials are size-reduced and the ductile materials are liberated and remain as an oversized fraction. The feedstock can include infrangible materials that also remains as an oversized fraction. The pulverized material is then subjected to a separation stage, which may include mechanical and/or magnetic screening, to separate the oversized material comprising the ductile material, and optionally larger particles of the infrangible material, from the size-reduced material comprising the frangible material, and optionally small particles of infrangible material.

摘要： A process for treating a fines stream in a material recover facility (MRF), comprising: providing an MRF fines stream comprising breakable material and ductile material: subjecting the MRF fines streams to a one-pass kinetic pulverization stage to produce a pulverized material comprising a size-reduced fraction derived from the breakable material and an oversized fraction derived from the ductile material; withdrawing the pulverized material from the kinetic pulverizer; and subjecting the pulverized material to separation to produce a size-reduced stream and an oversized stream. Also provided is a system comprising a kinetic pulverizer, a pulverizer conveyor and a screen operatively coupled to the pulverizer conveyor to receive a pulverized stream and produce a sized-reduced stream and an oversized stream. The system can also include a magnetic separator and a dust collection system respectively located upstream and downstream of the kinetic pulverizer.
