     · The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in realscale grinding plants. In fact, laboratorygrinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement particle size distribution (PSD) curves.

  • Portland cement clinker

    Portland cement clinker overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

  • Energy Use – Cement

    Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
