Increased grinding pressure, for example, immediately results in an increased grinding rate and consequently an increase in the coal mass flow following an increase in primary air. Based on the assumption that the feeder rate, or coal fed into the mill, remains constant, the level of coal in the mill will decrease.
Coal is the mainly energy consumption, so it is the main problem to improve coal fired efficiency for thermal power plant. Traditional ball bill has large power consumption in the process of production, and fineness of pulverized coal is not up to the standard. Great Wall Machinery put forward coal vertical roller mill solution for power plant, which can effectively improve …
