GreyStone has a new, fully portable, Self-Erecting Screen Tower for sand, gravel and aggregate producers who move classifying equipment from site to site at least once a year. The screen tower, which uses a horizontal, vibrating, three-deck wet screen, is a more cost-effective and flexible alternative to permanent and stackable screen supports. It eliminates costs and production losses due to inactivity of some permanent screens, and assembly and take down time for stackable screen supports. It takes less than two days to tear down and set up, and can easily be moved by semi-tractor, allowing producers with a portable classification tank to utilize a completely portable classifying system. It can act as a primary screen for operations that screen six-inch minus material or as a secondary or tertiary screen for plants that screen larger material. Fed by either a dredge or conveyor, it feeds material 3/16-inch minus into a classifying tank and stockpiles up to three material sizes from the three decks for further processing.
The screen tower is raised and lowered at the touch of a button, using a winch-driven system with pulleys to move the tower up and down. It is available in custom screen sizes up to 6 by 20 feet. Heights range from less than 14 feet in the low position, up to a maximum height customized to each specific operation.
