Difference Between Open Loop & Closed Loop Circuit Globe

One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action. While in the closed loop system the desired output depends on the control action of the system. The other differences between the open and closed loop system are shown below in the comparison chart.

the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry reporting as fresh feed to the second milling circuit will increase.

Open loop and closed loop circuits Open loop and closed

Open loop and closed loop circuits Open-loop: Pump-inlet and motor-return (via the directional valve) are connected to the hydraulic tank. The term loop applies to feedback; the more correct term is open versus closed "circuit". Open center circuits use pumps which supply a continuous flow. The flow is returned to tank through the control valve's open center; that is, when the control valve is

Ball Mill Operation -Grinding Circuit Startup & Shutdown

Feb 01, 2016 The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
