difference between open and closed circuit jaw crusher. Open or Closed Circuit Crushing. High-speed, short-throw crusher, such as the Type R or cone, will reduce practically all of its product to a one-way dimension not exceeding the close-side setting of the crusher; hence, in a closed-circuit operation, if the crusher-setting is anything less than the square-opening product size, practically ...
Most modern closed-loop CNC systems are able to provide very close resolution of 0.0001 of an inch. Closed-looped systems would, naturally, require more control devices and circuitry in order for them to implement both position and velocity control. This, obviously, makes them more complex and more expensive than the open-loop system.
