Horizontal grinder with side tilt feed roller

摘要

A feed roller assembly for a horizontal grinder having a hammer mill and a conveyor moving material to be ground or processed toward the infeed side of the hammer mill includes a side tilt frame hingedly connected along a first axis to a hammer mill frame and a feed roller frame hingedly connected along a second axis to the side tilt frame. In a first position, the side tilt frame and the feed roller frame are downwardly hinged so as to engage the feed roller with feed material. In a second position, the feed roller frame is hinged upward about the second axis to disengage the feed roller from the feed material and the hammer mill frame. In a third position, the side tilt frame is further hinged outward about the first axis to pivot the entire feed roller assembly away from the hammer mill frame.

主权项

1. A horizontal grinder with a side tilt feed roller assembly comprising:
a hammer mill frame disposed around and supporting a hammer mill assembly rotating about a hammer mill axis; a side-tilt frame hingedly coupled to a first side frame assembly of the hammer mill frame above the hammer mill and pivotable about a tilt frame axis extending substantially transverse to the hammer mill axis and between a closed position extending across said hammer mill frame and above said hammer mill and an open position; a feed roller rotatably coupled to a feed roller carrier hingedly coupled to the side-tilt frame about a roller carrier axis extending substantially transverse to the tilt frame axis; said feed roller carrier pivotable about the roller carrier axis between a use position in which said feed roller is positioned in front of said hammer mill assemlby to engage material fed into the hammer mill assembly and a raised position in which said feed roller and said feed roller carrier are positioned over said side-tilt frame; said feed roller and said feed roller carrier in the raised position being pivotable with the side-tilt frame about the tilt-frame axis between the closed and open positions; wherein when the side-tilt frame is advanced to the open position, the center of gravity of the side-tilt frame, the feed roller and the feed roller carrier extends past a vertical plane through said tilt frame axis.
