large number of viable design and operating candidates. Introduction Rotary kilns (Figure 1) are used for a range of mineral processing operations. Kilns range in size from 2–6 m in diameter and can be 50–225 m long with an operating mass of up to 3000 t. Two of the most common applications are for cement production and sponge iron production.

The cement kiln

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated ...

Rotary Kilns

Rotary kilns are a critical component in manufacturing of cement, lime and mineral products. With over 35 years of experience servicing these industries, A-C Equipment plays a critical part in the ongoing design, fabrication and repair of these rotary kiln installations.

A. A Boateng, in Rotary Kilns (Second Edition), 2016. 10.4 The Cement-Making Process. Rotary kilns are synonymous with cement making, being the workhorses of this industry. There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing environmental ...

Combustion of large solid fuels in cement rotary kilns

rotary kiln material inlet end, kiln riser duct and lower cyclone stages. Clinker quality may also be affected by minor compounds from the fuel ashes or from unburned carbon leaving the rotary kiln with the clinker. This thesis provides an insight into the utilization of solid alternative fuels in the material inlet end of rotary kilns.

Cement Kilns: Design features of rotary kilns

Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.


Table 2.2: Cement production and cement consumption in 1995 (Figures in 1,000 tonnes) In the European Union cement is produced in 320 plants of which about 70 are grinding plants without kilns. See Table 2.3. The total number of kilns in the EU countries is 437. They are not all of them currently in operation. Only very few kilns
