The rabble arm has blades (or rakes) which extend downwardly therefrom for contacting and raking particulate metalliferous material in a roasting hearth. The rabble arm cleaning device which is cooperably associated with said rabble arm comprises a hammer assembly pivotally mounted on said rabble arm, the pivotally mounted assembly having a weighted longitudinal member disposed below the pivot and extending longitudinally of said rabble arm in gravity contact with said blades, a cam-reacting member being disposed above said pivot with its free end extending above said rabble arm for making contact with a stationary cam disposed in the path of travel of said cam-reacting member, said cam-reacting member and said weighted member forming a coacting couple about said pivot.
