If a switch is added to the circuit but is open, no current ﬂows.

##### What is Closed Circuit Crushing?

Reply: Closed-circuit crushing is a means of controlling product top size by screening the product and then returning oversize material to the feed end of the crusher for another pass through the machine. While it may be possible to obtain a specified top size from crushers without using a closed-circuit system, it is not always desirable.
