The circuit breaker can be operated separately or in combination with an ANDROMAT® manipulator system. The ingate to be broken is fed to the circuit breaker and fixed in a 3-point support. The crushing process is optimized in such a way that the outer ends of the circuit material bend downwards for safety reasons. In order to avoid the introduction of force feedback into the feeding mechanism, the bottom plate of the circuit breaker is supported on a combination of silent blocks. The ideal working position of the circuit breaker is directly above the feed chute.
