A mass and energy balance for a cement rotary kiln was developed. Process parameters were taken from a full-scale cement plant in Norway which produces around 3400 tons of clinker per day. Only the rotary kiln (main burner) was included in the main model, however a mass balance for the precalciner (secondary burner) was also carried out in order to determine the total
The entire production process of cement is summarized as "two grinding and one firing", in which "one firing" is the process of firing the raw material prepared by grinding into clinker under the high temperature of the rotary kiln. Therefore, the rotary kiln is the main engine in cement production, commonly known as the "heart" of the cement factory.
In a typical process for the manufacturing of cement, and as will be explained in more detail in reference to the drawings, the rotary kiln is typically at least 200 to 400 feet long and is inclined at an angle of about 1/2 inch to a foot from the horizontal to permit the feed to move through the kiln by gravity flow.
Specification of rotary kiln by various processes. It has been developed for use in cement calcining, but today rotary kilns are used in a variety of thermal processing applications such as mineral extraction, metal smelting, and waste incineration. The most commonly used field is limestone processing for raw material firing to produce cement. In recent years, kiln has
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. Hatch has developed a proprietary one-dimensional kiln model to
A Boateng, in Rotary Kilns (Second Edition), 2022. 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
Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.

Wet process kilns. 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 and the
