From the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric feeders.
In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.

The four most common coal pulverizers types 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.
Ball Mills: A ball mill is a cylindrical machine with a horizontal axis, some of which contain grinding media such as steel balls or steel rods. The mill receives coal feed and grinds it by the impact and friction of rolling balls. For grinding coal, ball mills are frequently used in cement factories and coalfired power plants.

The ball ring mill has a mill housing, a grinding track (6) and grinding balls (7) which are activated by an outside force and run on the grinding track. For each grinding ball a separate pressure mechanism (8) is provided for transmission of the outside force on the grinding balls. Each pressure mechanism has a ball dome surface as pressure surface acting on the grinding balls.
