Coal Fineness: It is understood generally that the finer we grind, the easy it is for burning. However, the fineness required will always be directed by where to fire and what type of coal it is and lastly the fineness will be dictated by the risk factor involved in finer grinding high volatile coals. ... Coal Mill Safety parameters: Position ...
The coal vertical mill adopts the temperature detection device, the online gas analyzer and other explosionproof measures to ensure the safe operation of the equipment. An explosion proof valve is arranged on the upper shell to prevent the explosion of the pulverized coal in the mill and ensure the safe use of the equipment.
This test method provides a means for assisting in the evaluation of pulverizers and pulverizer systems in terms of fineness specifications. It may also be used to confirm the influence of coal fineness on combustion performance and to evaluate carbon loss. By consent among interested parties, it may be used for evaluation of coal fineness in preparation, pneumatic transfer systems, etc.
Dec 13, 2011· Coal parameters affecting pulverizer output: While selecting a pulverizer, the coal characteristics play an important role. The Hard grove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output.
Coal mill is used for grinding and drying coals with high, middle and low hardness, with reasonable structure and high grinding efficiency, and it is one ideal equipment for coal powder making.
