A bowl mill for a coal pulverizer with an air mill for primary entry of air, comprising a substantially closed separator body (2) having a central axis and a bowl-like grinding table (3) mounted on a shaft (4) rotatable about said central axis, cooperating with a plurality of grinding rolls (6).The airmill is provided with multiple entry openings (17, 17 18, 18 21, 25) on the ... Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill puffs. Explosions in a pulverized coal system are normally called puffs.. A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

Bowl mills are very important auxiliaries for boiler units of thermal power plants, as they help to enhance the stability and efficiency of combustion process of coal by pulverization. This inadvertently increases the surface area of the coal, thus enhancing the combustibility in the furnace chamber of the boilers. Bowl mills The end result is that pulverizer fineness at the lower loads increases. On pulverizers with 75% passing 200 Mesh fineness at full load, minimum load fineness can be as high as 85% or more. In some instances, an excessive quantity of finely ground coal particles on the bowl acts as a powder lubricant between the roll and bowl.
