The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from to with a typical value of An air to fuel mass ratio of produces a primary stoichiometric ratio of approximately, or 16% of the air necessary for complete combustion of the coal.
In this technical article electrical systems in cement plant will be touched upon. All machines are driven by electric motors. Majority of the motors are 400 440 volts. A selected few motors of higher ratings are MV motors with 3300, or 6600 or 11000 volts. Most motors are fixed speed and unidirectional motors.
Coal mill. The coal mill uses coal, coke or grinded pet coke with different size of balls. Larger sized balls are used for impact grinding and the smaller balls are used for attrition grinding. Cement mill. This is the final step in a cement manufacturing process. In this step, the clinker is ground together with additives in a cement mill.
