Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%.

The Description and Function of Ball Mill： Ball mill is the key equipment for recrushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry.

10%Ball mill, providing grinded coal for the boiler, is an important role in a thermal power plant and consumes 15 ~ 25 % of the whole energy consumption of the thermal power plant. Therefore, ensuring the efficiency of ball mill operation is of consequence for the sake of energy.

Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in …

Abstract: A ball mill pulverizing system is a typical strongly coupled multi-input multi-output (MIMO) plant, which is also nonlinear and widely used in coal-fired power plants. A conventional PID control strategy is not effective for its regulation, so it becomes a difficult problem in thermo-power automation.

A ball mill efficiently operated performs a wide variety of services. In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the Steel-Head Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness.
