Reinforced ring hammer

摘要

A ring hammer for a reducing machine includes an annular body and tooth projected radially from the annular body and arranged in two rows, with the teeth of the one row being spaced axially from the teeth of the other row and further being offset circumferentially from the teeth of the other row. A reinforcing ring extends around the annular body in the space between the two rows of teeth and is formed integral with the annular body and the teeth of the two rows. The reinforcing ring tapers downwardly to the side faces of the annular body in the spaces between successive teeth of each row so that the teeth possess greater depth at their outside faces than at their inside faces. The reinforcing ring strengthens the ring hammer and renders the teeth less susceptible to breakage.
