The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills. However if the primary air fan power is also taken into account, in the case of a pressurized mill the power consumption is lower only by about 15%.
Analysis is fairly straightforward, with the coal thoroughly burnt and the ash material expressed as a percentage of the original weight. Typical range Ash content is 5 to 40%. The fixed carbon content of the coal is the carbon found in the material which is left after volatile materials are driven off.

Abstract: Coal mill is an essential component of a coal-fired power plant that affects the performance, reliability, and downtime of the plant. The availability of the milling system is influenced by poor controls and faults occurring inside the mills.
Coal mill pulverizer in thermal power plants - SlideShare. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.

The fine performance of coal mill is essential for better combustion. Coal gets ground by grinding elements in stages. Hot primary air from air pre heater drives moisture from coal and acts as carrier to transport pulverized coal to the boiler through pipes.
2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner ...
On the contrary. correlation results (continuous line) is represented together with measured values of mill drive current. because the other option would lead to an excessive total coal flow. making air preheaters performance analysis more involved.
