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.

IPC Classes  ?

• B29B 17/02 - Separating plastics from other materials
• B02C 19/00 - Other disintegrating devices or methods
• B02C 23/38 - Adding fluid, other than for crushing or disintegrating by fluid energy in apparatus having multiple crushing or disintegrating zones
• B29K 309/08 - Glass
• B29K 511/14 - Wood, e.g. woodboard or fibreboard
• B29L 31/08 - Blades for rotors, stators, fans, turbines or the like, e.g. screw propellers
