ABSTRACT:
The invention is a mill rod puller which removes mill rods from hammermills or similar devices through the use of a reciprocating hydraulic action. The rod puller includes a support frame and a rod extension that attaches to an end of the rods of the hammermill. The rod extension has a number of attachment points for attaching the rod extension to a reciprocating force generator. The reciprocating force generator then moves away from the hammermill, and pulls the rod extension with it, and also pulls the rod to which the rod extension is attached, in increments.
