Experimental study on improving cement quality with oxygen .

in firing too long, the clinker burns too much, leaving the liter weight too high and reducing the clinker quality. As the chemical reaction of material in the kiln remains incomplete, most of the clinker particles are small with a fine powder and low liter weight indicating that the temperature in the kiln is low. Therefore, liter weight.
