As one of leaders of dust collectors for tbm industry, SBM always seeks innovation & excellence.
dust from the contaminated intake air and discharged clean air towards the front of the TBM. Workers on the TBM would then be exposed only to dust generated at the TBM rather than both TBM dust and intake dust. The result would be to produce dust levels below the exposure limit for all TBM locations except those close to the cutter head. The air
