With the construction of more and more coal-fired power plants, the powder mill market is extremely hot in recent years, Clirik engineers give you a brief introduction of how to choose powder mill.
   
China's coal has the characteristics of change range wide, wear resistance and higher ash,to  solve these problems, while the introduction of foreign advanced technology, but also the introduction of powder mill output is calculated, the correction factor curve and mill thermal calculation software more suitable for our coal.
   
When you Select powder mill, pay attention to consider the pulverizing system design coupling relationship. To design a sufficiently flexible milling system to deal with power plant design coal and possibly somewhat less checking coal burning, and correctly grasp the the selection margin requirements of the medium-speed mill. Total moisture in coal, such as lignite, powder mill contribute generally able to meet the requirements of the boiler coal burning mill ventilation is limited, the boiler hot air temperature is limited, it can only be based on powder mill drying capacity to control the amount of coal powder mill.
    
In recent years, China's medium-speed powder mill availability factor, run coefficient has increased annually, and the availability factor of the medium-speed powder mill, run coefficient were higher than the low-and high-speed mill. With the large capacity thermal power units put into operation in recent years, the use of medium-speed powder mill more and more small, medium-speed powder mill initial investment costs, grinding coal power consumption low, low load operation, the unit consumption the power increase much, has become the preferred solution for large thermal power plant with a powder mill.
