Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs. For example, water and chemicals, as well as energy enter and leave the boundaries of a watershed system. Outputs from one part of the system are inputs for another part.
There are many factors that impact on mill sizing and performance that you do not mention, particular grindability, desired product size, open or closed circuit, wet or dry grinding, what material you are grinding, and others. First off, a ball mill will generally draw less power than a rod mill, so that is not surprising.

The salt can be re-used once the heat is extracted in a closed-loop system. In some embodiments of the invention, the salt is conveyed down the well by a pneumatic conveyer system, or in other cases by using a mechanical system, such as a screw drive. Once returned to the surface, the molten salt can be used to heat graphite blocks for energy ...

Researchers pioneer viewing deep rock fractures for geothermal. Researchers of the Pacific Northwest National Lab in the U.S. have pioneered a new subsurface imaging technique that allows monitoring deep rock subsurface fractures for geothermal. Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock.

Open Loop vs. Closed LoopControl System. Dryer example. Timed Mode (open loop) Once you turn the dryer on it will run until the timer is finished. It doesn't matter how wet or dry the clothes are. Power wheelchairs are another example of an open loop system – the joystick controls rate/speed "More" or "Less" dry Mode (closed loop)
A great many open and closed loop controls can be found in the cement production, however, the proper control of the operation-triplet, i.e., proportioning — burning — grinding can ensure that the overall control aim is reached, and that the other controls are auxiliary ones. Therefore, these three areas are investigated next.
