A coal mill is also called a coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process.

Introduction. Replacing some of the coal by biomass is an effective way to reduce CO 2 emissions from pulverizedcoalfired power plants and integrated coal gasificationcombined cycle power plants. However, compared with coal, biomass has lower grindability in the existing roller mills 1 and a lower calorific value per weight. 2,3 The maximum biomass cofiring ratio for stable operation is ...

The coal mills are fed from different bunkers which may not be synchronized in terms of coal grades (Xia, Peng, Zhang, Yang, Chen, 2011). Secondly, coal change in a mill or a boiler is a gradual process which may take several hours (Tuttle, Blackburn, Powell, 2020) to transition from one coal to another. Both unintentional and planned ...

The effect of coal moisture and pulverized coal moisture on the pulverizing system was considered in establishing a mass and energy balancebased dynamic mathematical model of a coal mill. The parameters of the model were identified by using the genetic algorithm and later validated with measurements. An extended Kalman filter was designed to ...

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
