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 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln.

In the cement industry coal mill fans are used to supply the required air for burning coal and remove the exhaust gases produced after burning. This is where the coal is grinded into the proper size to be fed into the burner. The coal mill fan moves the coal into the grinder. Thus these fans help ineffective burning of coal inside the mill.

Extraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
