varies with mill types but are also largely influenced by coal feed rate, HGI variations, spring pressures, coal fineness, mechanical alignment of the grinding elements, bearing condition, optimum or reduced air/fuel ratios, etc. Our experience proves that monitoring mill HP/ton consumption for a given fuel HGI and/or mill fineness can
The coal goes through a moderate grinding process and then is stored in a coal bunker. afterwards the coal is typically delivered to a power plant via rail or conveyor belt. The coal is transported by conveyor and tripper cars to coal hoppers / silos. These hoppers feed ball mills which is turn fed the pulverized coal to the boilers.
ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
