2. The limestone is combined with clay, iron ore and sand. It is then ground in a crusher and fed into. 3. Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln. In the kiln, the powder is heated to 1500oC. This creates a new product, called clinker, which resembles pellets about the size of marbles.

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 ...

The process that cement raw materials is sintered in a kiln is the key to the quality of cement clinker. In the sintering process of cement raw material, the useful components decomposed by various raw materials at 1000 °C are mainly: calcium oxide (CaO), silicon dioxide (SiO 2), aluminum oxide (Al 2 O 3), and ferric oxide (Fe 2 O 3).
