TOMECO Successfully Restores D3000 Fan Impeller and Cone for Song Thao Cement Plant

Emergency Situation: Production Shutdown Due to Severe Industrial Fan Failure

Recently, TOMECO An Khang Factory received an extremely urgent request from Song Thao Cement Plant:
their critical D3000 fan impeller assembly and fan cone had suffered severe damage, including tearing, heavy wear, and serious corrosion. This incident directly threatened the production schedule, caused significant economic losses, and affected the livelihoods of hundreds of workers.

The urgent requirement was clear: The cement fan impeller had to be repaired and delivered in the shortest possible time.
