  • Anti-spin method and apparatus for conical/gyratory crushers
    Patent number: 6315225
    Abstract: An anti-spin mechanism includes fingers disposed at a bottom portion of a crushing gap. In this way, the anti-spin mechanism does not interfere with the crushing apparatus as do clutch-based, anti-spin mechanisms. The anti-spin mechanism relies on mechanical prohibition of rotation of the crusher head with respect to the bowl due to finger-on-finger engagement. The fingers can be mounted on mantles, bowl liners, bowls, housing, or crushing heads to achieve anti-spin functions.
