Surely; there are a number of plants using oxygen enrichment technique but still not commercially due to its high cost. If market demand exists with good prices for cement then oxygen enrichment can be a good option. Table-1 shows a number of kilns in the USA using oxygen enrichment of either the main burner or the precalciner.

Removal of this excess water necessitates the use of a longer kiln for the wet process. The total power consumption in this process is also higher and the output lower than in the dry process. However, blending is much easier in a wet state. Most modern plants opt for the dry process with preheaters and precalciners. Precalciners (see Figure 3) are useful because a part of the burning process ...

The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers which transport the materials and unload into hoppers ...
