The mills used for coal grinding and drying are either tumbling mills or roller mills. Tumbling Mills. The tube mill or ball mill is especially suitable for the indirect firing system, i.e., where there is no direct connection between mill and kiln and where the pulverized and dried coal is stored in an intermediate bin of ample capacity. Thus the mill can be operated economically at a ...
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.
