Cement Clinker Quality Control During Clinker

In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker. 1. Lime Saturation Factor. The lime saturation factor (LSF) is a ratio of CaO to other oxides, it is used to control the proportion of cement raw meal.

Burning alternative fuels in cement kilns Cement

1 Suitability of cement kilns for the combustion of secondary fuels. Compared to other high energy-intensive production processes of cement clinker burning process allows a relatively high potential to use secondary fuels [1].This is due to the robustness of the clinker burning process and in its principal layout as a countercurrent process.

Clinker production increase and freelime standard

Cement manufacturing is a complex and energy-intensive process. A key operation in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker in the kiln. This operation, involving intensive heating up of raw materials in a conventional control of the cement kiln requires an experienced operator who
