Advanced Control Algorithm for Coal Mill

The principal control of the coal mill is the raw coal in-feed according to the load variation, which is indicated by the variation of the main steam pressure The quantity of the in-feed raw coal is therefore the control variable and the steadiness of main steam pressure is the control target This papel­deals mainly with the control of the fan-type coal mill for the direct firing system of .Coal can be fed and removed from both sides of the mill Half mill operation for partial loads allowed Input coal size 25 mm white output is 70 to 90 microns.

ATOX coal mill

through the mill A variable amount of cleaned gas can be recycled from the grinding system filter to maintain the required flow for separation and convey- ing through the mill, independent of the amount of hot gas needed for drying The ATOX coal mill has a water injection system to compensate for low water content in the raw coal, which allows increasing the amount of hot gas instead of .Mill operating conditions including mill speed (for circuits with variable-speed drives), density, and total mill load The effect of feed hardness is the most significant driver for AG/SAG performance: with variations in ore hardness come variations in circuit throughput.
