Sep 30, 2017 Closed-center systems are always under pressure but oil does not flow until you activate a lever asking the system to perform. Closed systems build and hold pressure, and, in the past, took some hits because the pressure held at high levels made initial power at start up more difficult.

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.
