5.4: Open Versus Closed Systems
We can also distinguish between open and closed systems: in an open system both matter and energy can enter or leave (we can keep track of both) whereas in a closed system the amount of matter is constant and only energy can enter or leave. Whenever we look at a system our first task is to decide whether the system is isolated, open, or …

Measuring the crusher setting
crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its open-side setting (OSS). However, the adjustment of your crusher is performed at its closed-side setting (CSS). OSS is measured while the crusher is stopped. CSS is calculated by deducting a certain amount (the average stroke) from the OSS.
