Abstract: The abrasion of the vane wheel of pulverized coal exhauster in Shandong Bainian Electric Power Development Corporation Limited was not uniform, which caused the larger vibration of the bearing pedestal. The procedure of threepoint method for dynamic balance was introduced. After the balance weight block was added in accordance with the calculation, the vibration of the bearing pedestal was reduced to acceptable value, and which is helpful for safe operation of the pulverized coal exhauster.
