Air Balance In Cement Process

How Cement Is Made

The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains.

Cement Process & Energy Saving

Air leakage may bring about an increase of both fuel consumption and fan power consumption. Air leakage occurred in kiln and pre-heater increases fuel consumption in order for heating leaked cold air up to process temperature. However, air leakage in EP and raw mill does not normally increase fuel consumption, but it increases required power
