flow of coal into vertical spindle mill

  • Improving Coal Pulverizer Performance and Reliability

    The four most common types of coal pulverizers are: Ball-Tube 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 by aseries of

    dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through ple discharge coal pipes leading to the burners, while oversized coal particles are rejected and returned to the grinding zone for further grinding.

    also the pulverised coal in mill and the raw coal fed into the mill contribute to the variation of the pressure. From the working principle of a Tube-Ball mill [7], it is known that there is actually no rotation mechanism like paddles spinning inside of the mill. The mill outlet pressure is a compromised aerodynamic result among the mill inlet
