Effect of Drying Temperature on the Output of Coal Mill
The grindability of coal represents the difficulty of crushing coal and affects the energy consumption of pulverizing system.This paper studied the effect of drying intensity on Hardgrove grindability index(HGI)of Datong bituminous coal and Yuanbaoshan lignite through a series of drying tests.The influence curve of drying intensity on HGI is collected.The influence of drying on grindability index is not only reflected in the change of moisture,but also in the change of coal structure during drying.It can guide the adjustment of parame-ters such as air volume and primary air temperature of various drying media during the opera-tion of coal mills in thermal power plants.By adjusting the drying strength of coal,energy-saving of the pulverizing system can be achieved.
