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.In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, than 80 of raw material is limestone.
Additive) are proportioned and ground in Cement mill (one Closed circuit ball mill in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard. For instance (Clinker+Pozzolana+Gypsum) are proportioned and milled.2 The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process.
Ball mills (Fig 1.1) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as grinding media and driven by side or central drive.Cement mill . The cement mill subject of the loss described in this article is a ball mill and consists of a horizontal cylinder, closed at both ends by heavy cast walls (Fig. 1).
