| Abstract: | The labyrinth packing device of the ZGM 95 medium speed pulverizer consists of drive shaft, labyrinth packing and packing ring. The device was liable to air inleakage and dust inleakage due to the abrasion of the labyrinth packing. The installation work was heavy at the same time. After the labyrinth packing was reformed into floating ring seal, the problem of air and dust leakage was solved. The maintenance time of the pulverizer is reduced, as well as the installation workforce. The operating condition of the polverizer is also improved. |
