There are two main types of kilns to produce cement: the Vertical Shaft Kiln and the Rotary Kiln. The Vertical Shaft Kiln or VSK is probably the first type of kiln that was used and it can be traced back to the 5th century A.C. in Greece, when they were used for limestone calcining (Reiter, AC, 11/1997, p. 23). In the 20th century, they have ...

Our High-Temperature Shaft Kiln sets the benchmark in the refractory industry. By utilising the preheated air as secondary air, which has previously been used for cooling the product at the discharge end of the kiln, we ensure that very little heat is lost in the process – and achieve superior thermal efficiency. Furthermore, thanks to the vertical kiln's high …

In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energy-efficient, eco-friendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.
These kilns are smaller than cement kilns and usually have three parts: a drying kiln or pre-heater, an expansion or burning kiln, and a cooler. Their typical capacity ranges from 15 to 30 t/h. The expanded clay kilns shown in Fig. 11 have successfully been repurposed to produce calcined clay.
However in the, U.S., vertical kilns have been largely replaced by rotarykiln systems mainly because they require less laborand have the highest output by reducing the amount of spalls. A summarized analysis of the two technologies is shown in Table 1. Technology comparison Vertical kilns Rotary kiln systems Capital Investment Lower Greater

Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...
