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 1.4 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 ...
Abstract: The ball mill coal-pulverizing (BMCP) system is a multivariable coupled system with long time-delay, large inertia and parameter uncertainties. This paper analyzes the dynamic characteristics of the BMCP system and proposes a control strategy based on a decentralized linear active disturbance rejection controller (LADRC).
