The blockage of the raw coal bunker often occurs in the thermal power plant. The wall vibrator and the air cannon can solve some problems, but cannot **** solve the blockage problem. For this purpose, our company has developed a new-generation blockage clearing machine - SSJ-5 type clearing machine. The product has been used in a number of power plants, and has been an ideal product for blockage clearing of the **** raw coal bunker, because of its ideal clearing effect and almost maintenance-free feature.
