Abstract
A material grinding mill of reversible character having hog-type hammers formed with chisel edges pivotally mounted on supporting discs, and further formed with landing areas positioned to contact the supporting discs so that the chisel edges are prevented from impacting upon or nicking the discs. The pivoting of the hammers allows them to rebound when encountering a body of hardened material so the hammer reverses direction, hence the landing area impacts on the discs and the discs are protected against being nicked by the chisel edges of the hammers.
