There is no clinker cooler baghouse or stack. Instead, some of the pre-heated air from the clinker cooler (tertiary air) provides combustion air to the precalciner. The rest is used in the in-line raw mill to dry the kiln feed materials. Therefore, all of the air from the clinker cooler eventually flows through the main baghouse and stack.

Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

Cement consists of a material called clinker which is formed when the raw material limestone is burned at high temperatures in a cement kiln [1]. In this process (called calcination) calcium carbonate decomposes and CO and CO 2 are produced [6]. Calcination is highly important from a climate perspective, since carbon bound in minerals is

What is Cement Clinker? Composition, Types & Uses

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
