The state of Virginia needed a carbon steel, Green Saw Dust Material Handling System to transport green sawdust. They contracted Green Globe Services to custom design a material handling system that would transport their green saw dust to a holding silo. This system was required to meet strict customer-provided specifications, including approximately 800 pages of supplied engineering requirements, and included specific safety components including explosion panels and an automatic power off system that would trip at any fault. Since this system was going to be installed in an operating facility, we were required to integrate our drawings with 40 sets of existing plant drawings to design the final system.

Upon review of the models for this turnkey system, we observed an engineering issue that resulted in our designing of a new bridging beam to allow for placement of a bucket elevator system.

As part of our design process, we created 3-D models of the processing system and generated 2-D CAD assembly drawings. We were responsible for component procurement, PLC programming, training, and transport of the freight to the jobsite.

Twelve weeks after drawing approval, we delivered a completed design for a system that could receive material directly from live bottom trailers, included screw type conveyers that delivered the media to the bucket elevators, two continuous chain-type bucket elevators to carry the sawdust to the silos, reclaim augers that undercut the entire mass, delivering material to the center hopper, all at a delivery rate of 15cf/m.
