A particle reduction device with a housing containing an inlet for receiving paper material into a flow chamber, at least two adjacently spaced particle reduction stages through which paper material flows from one stage to the other for reducing the particle size of the material, and an outlet for outputting processed material with reduced particle size. Each particle reduction stage of the paper particle reduction device includes an impact member that rotates about a central shaft for impacting material into smaller particles. At least one of the stages has a screen, located downstream from the impact member, that includes perforations through which particles of a sufficiently small size can pass. |
