Mar 15, 2016· Open circuit: The circuit is in an open state and there is no current in the circuit; That’s to say, it doesn’t work. Closed circuit: The circuit is in a closed state and there is current in the circuit. In other words, it works as normal.

### Closed or Open Circuit Grinding

Apr 01, 2017· A circuit is considered to be closed when electricity flows from an energy source to the desired endpoint (and back to the source) of the circuit. In other words, a closed circuit has a complete path for current to flow, whereas an open circuit doesn't, which means that it's not functional.

Reply: Hi Magee. Thank you for your question. Open circuit system means that materials pass through grinding machine one time. But if unqualified materials should be reprocessed by classifying equipment and powder satisfied requirements can be final products, this case can be called closed circuit system.

### Closed Circuit Grinding VS Open Circuit Grinding

You need a closed path, or closed circuit, to get electric current to flow. If there’s a break anywhere in the path, you have an open circuit, and the current stops flowing — and the metal atoms in the wire quickly settle down to a peaceful, electrically neutral existence. A closed circuit allows current to […]
