## Thermodynamic Performance Analysis of a Raw Mill

The energy efficiency equation of a raw mill system in the cement process is defined as: (44) η R M = m ˙ 2 h 2 + m ˙ 3 h 3 m ˙ 1 h 1 + m ˙ 4 h 4 36 Exergy Efficiency The exergetic efficiency analysis provides some significant indicators about the process and its parts for efficient useVertical roller mill for raw materials Application p rocess Raw material process Background Grinding raw materials needs lots of energy Tube mills had been used for grinding, but the energy efficiency level was lower Therefore, the introduction of highly efficient grinding equipment was anticipated DescriptionsVertical roller mill for raw Application p rocess materialsSo the material balance is now: Raw Materials = Products + Waste Products + Stored Products + Losses where Losses are the unidentified materials Just as mass is conserved, so is energy conserved in foodprocessing operations The energy coming into a unit operation can be balanced with the energy coming out and the energy storedCHAPTER 2 MATERIAL AND ENERGY BALANCES
