Abstract
A method and system for recycling wind turbine blades. A scalper scalps off balsa wood and foam from recycled composite chips, a lump breaker shatters the chips produced by the scalper, a hammer mill breaks fiber chips produced by the lump breaker to reduce the chips to strand clusters, a vibratory screen and cyclone air classifier or circular vibratory screener separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, another vibratory screen and cyclone air classifier or circular vibratory screener further separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, and a granulator pulverizes the resulting fiber strand into micro-fibers that can be used as reinforcement fibers.
