Coal Handling Plant And Coal Mills & Coal Feeder
Mill Feeders Feeders for coal mill are generally installed directly under hoppers with rod gate in between. The feeders are generally 2 to 3 m long and discharge on to conveyor or feeding chute to mill. For coal mill feeding, table feeders, belt feeders, chain feeders and weigh feeders have been used.
Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, complete drying of coal can be achieved in the mill. This results in increased mill exit temperature.

Coal feeders offered by us are manufactured from qualitativeraw material and are used to feed coal to pulverizing mills in power stationsand other industrial installations. Special attention is given to offer longlasting range. These enables controlled flow of coal from bunkers and pass itto Pulverizing Mills.
During conditions of a mill overload, the feeder speed demand signal should be reduced until the overload condition is resolved. Pulverizer Coal-Air Control System The primary control for a pulverizer is the coal flow demand to the primary air fans. The sec-ondary control is the coal-air mixture temperature.

Coal characteristics are integral to pulverizer system selection, sizing and performance. The production capaci- ty for each mill depends upon the following feed properties In general,the coal entering a mill system should be crushed to a size no larger than Maximum Feed Size —.
Three (3) 18 RPI drum-type coal feeders. When converting to P RB coal, the required mill coal flow rate for full load increased by 33 due to the relatively low heating value of P RB coal. In addition, the high moisture content in P RB coal resulted in a mill grinding capacity reduction by 17 . Both lower heating value and higher moisture.
