In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12 , and its moisture content should be controlled within 1.0 . The machines that are usually used to dry the coal fines are rotary dryers.

Clinker grinders are provided in boilers to grind large pieces of clinkers into small ones so that choking of the exhaust hole may be avoided but it is observed in many thermal power plants that clinker grinders are out of service due to negligence or being considered a redundant feature.
Clinker Formation Coal Mill Ppt - wallpaperpoets. Nov 15, 2017 reference Avoiding Clinker Formation in Thermal Power Plant Boilers Clinker or slag is a fused mass of non-combustible residue (ash) from coal. All coal has some amount of ash content bad coal has ash, that's all. Oxidation of the minerals. Kiln .This results in partial melting and formation of granular clinker. The length of each zone depends on the composition of raw material, the type of rotary kiln, and the cooling system employed. The clinker formed in the kiln drops into the clinker cooler where it gets cooled to a temperature between 120C to 200C.
Grinding grinding all materials into required fineness by cement mill. Cement ball mill and vertical cement mill are two common types. Homogenizing homogeneous kiln feed is the precondition of clinker production, so homogenization of raw materials guard a.Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker. Besides, the rapid cooling of the clinker in this process is convenient for cement storage and transportation.
