2013-2-19 Mill Control The Mill Control is a set of logic that regulates each pulverizer on the unit and sets the amount of coal fed to the mill, the amount of primary air flowing through the mill, and the temperature of the coal/air mixture leaving the mill. The mill control strategy is dependent upon the type of mill being used on a particular unit.

2015-4-16 mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.

2021-8-28 The discharge valves prevent the boiler gas from returning to the mills. The flapper type valve uses a disc that is removed from the coal stream when the valve is open. Removing the disc during operation eliminates disc wear and maintains a positive barrier between the mill and boiler when the valve is closed. MILL CLEARANCES

2020-7-15 In most cases, coal mill feeders are smaller than raw mill or finish mill feeders with capacities of 10-100 tons per hour. The #1 issue for coal mill operators is stickiness or coal build-up on all the material handling equipment, including the mill feeder. Raw coal, which is usually 3-4” inches or smaller, can have inherent moisture in it.
