rotary breaker
A breaking machine for coal, rock, or minerals. It consists of a trommel screen with a heavy cast steel shell fitted internally with lifts that progressively raise and convey the coal and stone forward and break it. As the material is broken the undersize passes through the apertures, so that excessive degradation does not occur.
