The hammer is pinned to the rotor body and allowed to swing, and lay back to some degree. The centrifugal force keeps the hammers extended, and the inertia force unleashed on the material shatters the rock on impact. The particles rebound off the impact plates or breaker blocks back into the hammer circle.
