Heavy-Duty Bar Grizzly Screen Valve
HSX Bar Grizzly Screen Valves feature independent heavy alloy steel finger rods that penetrate large rock columns individually. Engineered for mine ore pockets and quarry dump chutes where solid plate gates fail due to huge trapped boulders.

Individual Finger Insertion Technology
Allows each bar to weave around boulders without getting stopped.
Independent Bar Penetration
Individual rods slide through natural voids between large rocks, avoiding the dead stop resistance of solid flat plates.
High-Impact High-Manganese Alloy
Forged and heat-treated alloy steel finger rods withstand extreme impact from falling 5-ton rock boulders.
Emergency Feeder Maintenance Isolation
Provides 100% safe physical barrier above vibrating feeders or apron conveyors during downstream maintenance.
Customizable Rod Gap Pitch
Bar spacing can be tailored to act simultaneously as a coarse pre-screening grizzly to bypass fines.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Underground Ore Bins
Primary crushing stations, ore pass chute cutoff isolation.
Open-Pit Quarry Dumpers
Truck dump hopper throats, grizzly feeder maintenance gates.
Steel Plant Scrap & Ore
Blast furnace skip hoist loading hoppers, heavy scrap iron chutes.
Cement Limestone Crushers
Hammer crusher feed throat emergency shutoff.
