With the construction of more and more coal-fired power plants, the powder grinder market is extremely hot in recent years, Clirik engineers give you a brief introduction of how to choose powder grinder.
   
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 grinder output is calculated, the correction factor curve and mill thermal calculation software more suitable for our coal.
   
When you Select powder grinder, 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 grinder 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 grinder drying capacity to control the amount of coal powder grinder.
    
In recent years, China's medium-speed powder grinder availability factor, run coefficient has increased annually, and the availability factor of the medium-speed powder grinder, 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 grinder more and more small, medium-speed powder grinder 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 grinder.
