The Calciner plays an important role in the cement manufacturing process being the first step of the clinker production process. The main property of the calciner''s refractory lining is to withstand to the chemical attacks coming from the hot gases of the process. Refractory materials must have low porosity and good thermal stability.

Cement applications Concepts for calciners. Task The calciner is installed under the lowest cyclone stage. In this plant section, the raw meal is calcined (deacidified) by up to about 95 %. The energy input required by this stage (about 60 % of the plantʻs overall heating demand) is provided by means of special calciner burners, which can be ...
Jan 05, 2019· Total flow precalciner: In total flow precalciners, combustion takes place in a mixture of kiln exit gases and tertiary air. Combustion therefore starts in gases with about 10% to 14% oxygen and ends in about % to % oxygen. Raw meal from the preheater is fed into the bottom of the precalciner and is conveyed [.]

Since calciner technology was introduced in the 1960s, there has been no comparable leap in the pyroprocessing technology for the manufacturing of cement. Steinbiss in [1] provides a good overview of earlier developments in calciner technology, as well as a prediction of the economic prospects of burning residual materials.
The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. A calciner is a steel cylinder that rotates inside a heated ...
