An apparatus for extracting fibers free from contaminants in a substantially dry processing environment. Generally, the present invention provides an apparatus for extracting fibers of varying sizes and free from contaminants in a substantially dry processing environment. The apparatus for extracting fibers according to the embodiments of the present invention uses a separator system that receives a mixture of fibers and fine particulate matter, for disassociating fibres from fine particulate matter and contaminants. The separator system includes at least one screen having a specific mesh size for trapping/blocking fibres that are blown in to the separator system. The fine particulate matter pass through the screen and are collected. A sweep system is activated to physically remove any fibers pressed against the mesh, such that the freed fibers can be collected and stored in a container. The apparatus can include a material dry processing and/or defibering stage for receiving reduced paper and dry pulp material for separating out large particulate waste, and passing the defibered fibres and fine particulate contaminants to the separator system.
