In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At ''A,'' the raw meal largely decarbonates; at ''B,'' the temperature is 1000 C 1200 C and intermediate compounds are forming and at ''C,'' the burning zone, clinker nodules and the final clinker minerals form.
Mills are used for grinding raw material ball mill and vertical roller mill (VRM). The VRM combines the drying, grinding and separation processes into just one unit. In VRM, raw material from the feed mouth fells into the center of millstone, which moved to the edge of mill under the action of centrifugal force and is ground by
