Solution: We will write an energy balance, with our control volume as the entire earth. For this system, our goal is to calculate annual-average temperatures. Over time periods of 1 yr, it is reasonable to assume that the system is in steady state, so our energy balance is simply The energy flux in is equal to the solar energy intercepted by ...

magnitude of these energy flows.But while "natural man" is in balance with these heat flows, "technological man"1 has used his mind, his back, and his will to harness and control energy flows that are far more intense than those we experience naturally.To emphasize this point we suggest that the reader make an experiment. Experiment1.1

Nowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process.

• Bar 4 – Energy Gap: Subtract the benchmark (Bar 3) from the energy use for your mill (Bar 2). This is the energy gap between your mill and the benchmark. Although using a "floating bar" is not customary graphics, in our case it better represents the difference between your mill and the benchmark mill because the horizontal axis is
