A twin augered feed table having troughs in its bottom supports counter-rotating augers which feed the material to be processed directly upwardly at an angle into the rotor and faces of the hammers.
Claims10
A hammermill comprising a housing defining a grinding chamber having a rotor with a plurality of swinging hammers and a removable screen;
- an open material-receiving trough forming a feed table on one side of the housing;
- at least one pair of counter-rotating augers rotatively supported within said trough and flighting disposed about said augers for feeding material to be processed directly upwardly at an angle into the rotor and grinding chamber of said hammermill;
- said feed table rigidly affixed to said rotor housing and residing in a plane passing through the plane of said rotor, and means for rotating said rotor and said augers.
In combination with a mixing tank having a mixing chamber and at least one screw conveyor adapted to mix fluent material discharged into said tank;
- a hammermill apparatus comprising a housing defining a grinding chamber having a rotor with a plurality of swinging hammers and a removable screen;
- an open material-receiving trough forming a feed table on one side of the housing;
- at least one pair of counter-rotating augers rotatively supported within said trough and flighting disposed about said augers for feeding material to be processed directly upwardly at an angle into the rotor and grinding chamber of said hammermill;
- said feed table rigidly affixed to said rotor housing and residing in a plane passing through the plane of said rotor, means adapted to rotate said rotor and said augers, and transfer means for conveying said processed material from said hammermill to said mixing tank.
