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.

Potential of preparing cement clinker by adding the

2021-2-5  The cement raw meal was provided by the local cement industry in Xi’an, Shaanxi Province, China. The chemical compositions were presented in Table 4. The pre-dried fluorine-containing sludge was then heated at 105 °C for 24 h until it had no moisture, and treated fluorine-containing sludge was milled to pass through #200 (75 μm) sieve.

The cement kiln Understanding Cement

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
