  • Pulverizing Mills | Thermal Power Plant

    Pulverizing Mills Each of the six units at Drax has ten pulverising fuel mills, each capable of pulverising 36 tonnes of coal per hour Inside the mills, ten giant hollow steel balls, each 14 tonnes in weight and approximately 730 millimetres in diameter, crush the coal into a fine powder Crushing the coal into a fine powder makes it easier to burn it more completely When the hollow millThis mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table As the table rotates, the raw coal is pulverized as it passes underneath the rollers Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out theCoal Pulverizer Pallmanufacturers of coal pulverizing equipment The four most common types of coal pulverizers are: BallTube Mills This type of mill consists of a rotating tube filled with cast alloy balls Coal is introduced through two hollow trunnions on each side of the tube As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it Impact Mills Grinding Action is carried out byImproving Coal Pulverizer Performance and Reliability
