ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
capability can be used to increase the pulverizer and boiler capacity with the present coal or to maintain the present boiler load with a coal that is more difficult to pulverize. At Danskammer, the existing pulverizer capacity was increased by more than 15 percent while the coal particles larger than 50 mesh were essentially eliminated.
Coal mill is the equipment used for grinding and drying coal with different hardness and it is mainly composed of feeding device, principal axis, rotating the part, transmission part, discharging part, high-pressure starting device, and lubrication system.

This regulation, by sweeping pulverized fuel from the mill, is very fast; comparable with oil firing response, but needs the coal level to be maintained in the mill. A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a built-in ...
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
