Thermodynamic Performance Analysis of a Raw Mill System

Thermodynamic Performance Analysis of a Raw Mill System

Jan 01, 2018 The thermodynamic properties of material flows in the raw mill system for cement production were determined using EES software . The EES code was also employed to investigate the performance of the raw mill system and its parts. The heat loss rate from the raw mill system into the ambient environment was calculated to be 14,414.285 MW. The exergy efficiency of the raw mill

Re: Mass Balance - Page 2 of 3

Oct 06, 2010 Re: Mass Balance. subtracting Ash in clinker form g we get Amount of feed required to produce on kilogram of clinker . For me, not exactly. Subtracting Ash in clinker from g, you get the amount of meal required to produce a kilogram of clinker and this is not equal to the amount of feed.To get the feed, you need to add the amount of dust that is leaving the top stage of preheater with the gases
