  • Method and apparatus for disintegrating wallboard
    Patent number: 5577672
    Abstract: Sheets of defectively manufactured wallboard are loaded in a stack on a conveyor and are advanced intermittently to a shearing station where a shear periodically cuts through the stack to sever successive leading end sections from the stack. Each cut-off leading end section drops into a shredder which reduces the wallboard into small particles and chunks capable of being recycled.
