IMPACTS OF LOW RANK COAL UTILIZATION IN THE
Low rank coal utilization in sub-bituminous coal power plant will increase the quantity of coal consumption. Power consumption and fuel cost in coal handling activities will be higher than sub-bituminous coal. The mill performance is based on the variation of mill power (kW) as a function of mill capacity (C, kg/s) times product fineness (FThe energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are Energy-Efficient Technologies in Cement Grinding

Rod Mill Product Control and Its Relation to Energy Consumption
Energy consumption and pollution are current strategic issues that need to be addressed in the mining industry. Both have an economic and environmental impact on production, so their optimization, control, and mitigation are, at the very least, mandatory. Although rod milling has fallen into disuse in recent decades, some companies still use it The electric power sector has accounted for the majority of U.S. coal consumption since 1961. U.S. coal consumption by consuming sector and by amount—in million short tons (MMst) —and percentage share of total coal consumption in 2022 was: 1. Electric power—469.9 MMst—91.7%; Industrial total—41.9 MMst—8.2%; Industrial coke plantsUse of coal U.S. Energy Information Administration (EIA)

How to Calculate the Coal Quantity Used in a Power Plant
The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit. The cost of fuel is the main factor in the cost of a unit of electricity.4. ROLE OF MILLS • Produces Pulverized coal 80% of which passes through 200 mesh • Air mixed with Pulverized coal (PF) is carried to the coal nozzle in the wind box assembly. • PF from coal classifications and working of mills in a power
