Patent ID: 11883828
Assignee: TORXX KINETIC PULVERIZER LIMITED
Field: Chemical engineering (Chemistry)
Classification: CPC B  Y | IPC B

Claim 0:
1. A process for treating construction and/or demolition (C&D) debris comprising:
providing a C&D fines stream comprising a frangible material and a ductile material;
providing a kinetic pulverizer comprising a pulverizing rotor assembly disposed within an interior chamber, wherein the pulverizing rotor assembly is configured to rotate to form vortices that subjects the C&D fines stream to self-collisions within the interior chamber;
subjecting the C&D fines streams to a kinetic pulverization stage wherein the C&D fines stream is fed into the kinetic pulverizer to produce a pulverized material comprising a size-reduced fraction derived from the frangible material and an oversized fraction derived from the ductile material;
withdrawing the pulverized material from the kinetic pulverizer; and
subjecting the pulverized material to a separation stage to produce a size-reduced stream and an oversized stream,
wherein the C&D fines stream comprises gypsum and wherein the kinetic pulverizer is operated such that individual particles of the size-reduced fraction are less than 2 mm in diameter.
