Abstract
A material reduction apparatus for reducing materials having an admixture that resists reduction. The mechanism incorporated into the apparatus to provide a bypass of such admixture while avoiding shut down interruption of the materials reduction operation.
Claims12
A materials reduction apparatus, comprising:
- a rotor for having one or more features for reducing a material;
- a bypass arm proximally disposed to the rotor for causing reduction of the material passing there between, the bypass arm configured to pivot between a closed position whereat the material will be reduced and an open position whereat a passage is provided for a reduction-resistant component of the material;
- and
- a bypass control coupled to the bypass arm, the bypass control including a first force generating member adapted to provide a latching force to act on the bypass arm to resist movement of to the bypass arm from the closed position and a second force generating member adapted to provide a closing force adapted to urge the bypass arm towards the closed position once the latching force is overcome, the latching force being greater than the closing force.
1 more element
A materials reduction apparatus, comprising:
- a bypass arm proximally disposed to a rotor and configured to pivot between a closed position and non-closed position;
- and
- a bypass control configured to control pivoting of the bypass arm, the bypass control including a first resistance application mechanism adapted to hold the bypass arm in a closed position and resist an initial pivoting action until an ungrindable object is encountered, and a second resistance application mechanism adapted to allow pivoting of the bypass arm and urge the bypass arm towards the closed position.
