Cement Clinker Quality Control During Clinker Production

The following are several important factors affecting the cement clinker quality. 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. In the operation of the

What is Cement Clinker? Composition, Types & Uses

Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by c ement manufacturers when raw materials are found to be scarce or unavailable.

Minimization of variation in clinker quality

Abstract: Cement quality is typically assessed by its compressive strength development in mortar and concrete. The basis for this property is a well-burned clinker with consistent chemical composition and free lime. The main reason for the clinker free lime to change in situation with stable kiln operation is variation in the chemical composition of the kiln feed. This variation in

Predictive Model for Cement Clinker Quality Parameters

The quality of the clinker determines the property (such as compressive strength) of the cement made from it; the basis for this property is reported to be the result of a well-burned clinker with consistent chemical composition and free lime [1] . Keeping the quality of the clinker within acceptable range requires that measurement of the quality parameters be done from time to

Cement clinker

Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can be easily handled by ordinary mineral handling equipment, clinker is internationally traded in large quantities. Cement manufacturers purchasing clinker usually grind it as an addition to their own clinker at their cement plants.
