GreyStone’s portable Self-Erecting Screen Tower is ideal for producers that move classifying equipment from site to site. This horizontal, vibrating three-deck wet screen eliminates production losses of inactive permanent screens and assembly and take down for stackable screens. It can act as a primary screen for 6-inch minus material or a secondary or tertiary screen for larger material. Raised and lowered by one button, it feeds material into a classifying tank and stockpiles up to three material sizes. Available in custom screen sizes up to 6- by 20-feet, it takes less than two days to tear down and set up.
