This week’s video is of the portable wash plant at Four Corners Materials‘ (an Oldcastle Materials company) Animas Glacier Facility in Durango, Colo. A loader picks up material from the stockpile and feeds it to the wash plant. The belt on the wash plant has a variable drive that can speed up or slow down, depending on the feed stock. Five sprayers in the wet box soak the material before it hits the screen, then it goes through screws before hitting the dewatering screen that shakes out close to 50 percent of the water. The sand isn’t completely dry when it comes out of the dewatering screen, but needs only a day and a half for the rest of the water to leach out before it’s ready for use.
