CRITICAL MEASUREMENTS IN CEMENT MANUFACTURE

02 Temperature Measurements in Cement Manufacture The rotary kiln is the key component in a cement plant. It is a long steel cylinder, lined with refractory brickwork to protect the outer shell from the very high temperatures of the interior. Rotary kilns vary in size and typically have a ratio of width to length of 30 or 40:1.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing 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.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Rotary Kilns - KHD International

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.

Cement manufacturing - components of a cement plant

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.

Level and pressure instrumentation for the cement industry

To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air. Pressure

Thermodynamic Analysis of Cement Production Process

Previous work on exergy analysis of cement has sometimes been focused on the sub systems such as the rotary kiln [9], and the raw mill [10]. Most work has been on using only the operating data of the cement industry for the exergy analysis. This does not give room for parametric analyses that could give . suggestions for improvement of the process.
