The cement kiln segment held the largest rotary kiln market share in 2017, of 42% of the market. Cement kilns are used for the pyro processing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.
The cement clinker is ground with about 5% gypsum. Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the

Mar 25, 2017· Rotary kiln preheater is the usage of flue gas in the tail of the boiler through the internal heat sink will enter the boiler before the air preheated to a certain temperature heating surface. Used to improve the heat exchange performance of the boiler, reducing energy consumption. Vertical preheater has become an important equipment in the cement production line.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
The kiln is at the heart of your plant and plays a vital role in production. Timely, on-site kiln maintenance, such as hot alignment and resurfacing of rollers and tyres, as well as predictive online condition monitoring services can extend equipment lifetime and minimise wear and tear.
