Looks like a cement plant, possibly the Lehigh facility. The dome keeps the dry ingredients dry. They are transported up the conveyors to the horizontal rotary mixer/kiln at the top center of the facility, and then stored in the silos on the right. The large building at bottom center is where the various items are bagged or put into other shipping containers. There are also some train loading/unloading facilities at the lower right portion of the facility.
