Grizzly bar support

Bar Support

Any support beams between or directly under the grizzly bars will empede material flow and result in clogging and reduced production rates. Rock Tough's grizzly bar support is recessed below the grizzly bars, ensuring free flow of material down the screen face.

When larger grizzly bar openings are required Rock Tough's recessed lower spanner beam prevents damage as material moves off the screen deck. This option is available on our adjustable and fixed bar Extreme series separators.
