  • Apparatus and method for chipping wood debris
    Patent number: 6179232
    Abstract: A wood chipping apparatus includes a housing having a chipping chamber and an air chamber isolated by a fixed partition wall of the housing. A chipping drum is supported for rotation in the chipping chamber. A fan is supported for rotation in the fan chamber. The chambers have adjacent outlets that communicate with a discharge chute. Wood chips exiting the chipping chamber are received in the chute and are entrained by air issuing from the fan chamber to carry the chips along the chute. A baffle separates the outlets of the chambers and ensures that the air from the fan chamber does not backflow into the chipping chamber through its material outlet.
