I made some progress with the truck dump and conveyor loading area at Specialty Minerals. The dolomite limestone in this scene is actually dolomite limestone from the prototype Specialty Minerals plant in Canaan, CT. They have an open pit quarry about 1.5 miles from the processing plant. The trucks come in from the quarry and dump the raw stone in the bulk unloading area. Bucket loaders then pile it up and also feed the conveyor pit to the crushers at the processing plant.
