This is an active motion grizzly bar soil screener. It has 2.5" between screen bars and can remove most of waste rock to make soils much easier to work with.
8' wide x 6' tall x 4' deep makes it ideal to move to and from a job site with almost any trailer. The coil spring action allows deck to reduce angle temporarily when loaded with soils/rock and then bounce back to clear debris.
The screen deck is removable and we can customize screen size to fit your needs.
