The user simply defines his target chemistry for the raw meal by using the cement moduli LSF Lime Saturation Factor),SM (Silica Modulus) and AM (Alumina Modulus). Further constraints like

Raw Meal fineness x kiln output Page 1 of 3

Re: Raw Meal fineness x kiln output. Hello Rodrigo, Raw meal fineness directly influences product quality rather than production rate. However if raw meal finess is excessively coarse, or excessively fine, it can indirectly effect production rate.. Very coarse raw meal, especially containing substantial amounts of coarse quartz (>40 microns) and coarse calcite (>100 microns) will invariably

The cement kiln

However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the

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.
