Abstract:

The influence of semi-coke grain size on density of briquetted coal and strength of briquetted coke is studied.It is found that,as the grain size of semi-coke breeze decreases,the strength of briquetted coke increases,and then declines after reaching the peak where the grain size of semi-coke is below 3mm.The strength of briquetted coke produced can be increased significantly when the best blending ratio is adopted.
