Abstract
The reason of the upper shaking of ZGM133 G-1 medium speed coal mill from a 1 000 MW unit is analyzed in this paper
A series of measures are put forward to solve the provlem by the adjustment of dynamic separator speed. The corresponding curve between separator speed and coal quantity is also provided
and the operation parameters of coal mill are optimized. Meanwhile the safe and stable operation of pulverizing system is ensured by these measures.
