SHORT DESCRIPTION: Cast iron ball set in a wooden plaque. NOTES: This item was used in the coal pulverizer.Efficient coal combustion requires that all the carbon particles in coal should get sufficient air to burn and release the heat. When coal is burned on grates without any change in size or pulverizing its large size means that some of the carbon particles do …

As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.

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.
