Bradford Breaker
The Pennsylvania Crusher Bradford Breaker is a rotary crushing and sizing machine. Lifters raise material inside the rotating cylinder and let it fall, breaking it by gravity impact. Sized material exits through openings in the cylinder. With no hammers or blades, this method limits overcrushing and is particularly suited to brittle materials such as coal.
