TBM Scrubber
Envirosystems has designed several TBM scrubbers for specific projects, and would welcome an opportunity to talk to you about yours. We have designed TBM dry scrubbers for TBM’s from 1M to 5.5M in diameter. We can design to locate outside the gantry or inside the trailing gear and are very flexible with regard to volume required. Volumes above 30,000 CFM are not out of the question. We can now provide both Dry and Wet collectors.
TBM Scrubber
The dry scrubber shown was used on a refurbished Robbins TBM and used a screw conveyor under the dust collection hopper which discharged collected debris to the invert, automatically, through a rotary air lock on an adjustable time schedule.
16K TBM Scrubber
This is a 16,000 CFM Dry Scrubber used on a refurbished 4M Atlas-Copco TBM used for a short section of the Bill Bishop Toronto City Airport Tunnel. It was mounted centrally on the trailing gear and since there was not enough overhead clearance to accomodate a screw conveyor and rotary airlock, it discharged automatically from a unique clamshell dump hopper, through the trailing gear floor to the invert. This scrubber collected dust from the cutter head as well as several conveyor drops.
