Abstract
A material reduction machine includes an infeed portion operable to receive material to be reduced, and a cutting mechanism operable to reduce material fed in from the infeed portion. An outlet chute has a first end operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends along a curved path. The outlet chute includes, along a radially-inner side of the curved path, a foraminous interior wall providing communication with a sound attenuation layer.
Claims23
A material reduction machine comprising:
- an infeed portion operable to receive material to be reduced;
- a cutting mechanism operable to reduce material fed in from the infeed portion;
- and
- an outlet chute having a first end operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends upwardly from the first end to the second end along a curved path,
- wherein the cutting mechanism has vanes or paddles configured to forcibly blow reduced material upward and outward into the outlet chute, and
- wherein the outlet chute includes, along a radially-inner side of the curved path, a foraminous interior wall providing communication with a sound attenuation layer, and wherein the foraminous interior wall is opposite an outer wall of the outlet chute that defines a primary impact area for reduced material blown from the cutting mechanism along a radially-outer side of the curved path.
A material reduction machine comprising:
- an infeed portion operable to receive material to be reduced;
- a cutting mechanism operable to reduce material fed in from the infeed portion;
- and
- an outlet chute having a first end operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends upwardly from the first end to the second end along a curved path,
- wherein the cutting mechanism has vanes or paddles configured to forcibly blow reduced material upward and outward into the outlet chute, and
- wherein at least one lateral side of the outlet chute includes a foraminous interior wall providing communication with a sound attenuation layer, and wherein the foraminous interior wall is adjacent an outer wall of the outlet chute that defines a primary impact area for reduced material blown from the cutting mechanism along a radially-outer side of the curved path.
A material reduction machine comprising:
- an infeed portion operable to receive material to be reduced;
- a cutting mechanism operable to reduce material fed in from the infeed portion;
- and
- an outlet chute having a first end provided by a base portion of the outlet chute and operable to receive the material reduced by the cutting mechanism and a second end operable to discharge the reduced material from the machine, wherein the outlet chute extends along a curved path,
- wherein the cutting mechanism has vanes or paddles configured to forcibly blow reduced material upward and outward into the outlet chute,
- wherein at the second end, the outlet chute includes a discharge deflector that is angle-adjustable with respect to the base portion to adjust the trajectory of the reduced material discharged therefrom, and
- wherein the discharge deflector includes an integrated silencer.
