A centrifugal separator system separates particulate matter from an air stream produced by an industrial shredding machine. The system includes a housing having a cylindrical conical shape defining an interior chamber. An inlet positioned tangentially near the top of the housing introduces an air and particle mixture to create a vortex flow that centrifugally displaces heavier particles where they slide downward to discharge aperture. Clean air reverses direction and exits upward through a central top outlet connected to a HEPA filter for removing residual dust. A first silo directs is used to decelerate separated particles which are directed through a rotary valve providing an airlock to maintain pressures for optimizing centrifugal separation of particles. A second silo receives a bag holder for ease of securing a collection bag. The system provides efficient separation of particles with minimal maintenance and allows continuous operation.
