1. Trommel design uses a 12 sided polygon, 46 inch diameter drum, 9 feet of pre-scrub area with reinforced drive rings for Trommel drives.

• Polygon allows maximum break up of materials.
• Plant is designed to operate level or at 1 degree slope and by design, requires material flytes, which move material and ads additional mixing and breaking action.
• A side benefit of using a polygon design is that replacement parts do not have to be Rolled.

2. Trommel has replaceable wear plates in
all wear areas including Flytes.

3. Trommel uses urethane screens with tapered relief holes which we recommend.

• Urethane Screens almost eliminates the plugging issues that haunt trommels.
• Urethane life can be up to 10 to 15 times
that of steel.
• Screens can be change in minutes instead of days.
• Trommel design allows for steel (flat) punch
plates if desired.

4. Trommel drive.

• We incorporate a 4-point live drive system (which eliminates the chain).
• Fully hydraulic.
• Full variable speed control.
• Oversized gear boxes, bearings and shafts.

5. Internal spray tube with interchangeable brassspray nozzles for
final rinsingaction.

GRIZZLY PAN VIBRATORY FEEDER & SCREEN

Our grizzly pan feeders and screen decks incorporate up to 6” drive shafts with oversized bearings and have adjustable throw. They are also reversible (testing shows that reversing an incline feeder in some materials applications may force a better scrubbing action), have variable speed drive system to completely fine tune the feeder or screen, are fully lined with bolt on hardened abrasion resistant wear plates, and have a water spray system that is not attached to the vibrating unit (no more broken spray bars).

• Bolt in wear plates for easy replacement.
• Hydraulic driven.
• Full variable speed control.
• Independent Spray bars (not attached to vibratory unit, eliminates spray bar breakage).
• Each spray bar has its own valve and interchangeable brass spray nozzles.
• Can use either tapered Grizzly bars or Punch plate in screening area.
• Full catwalks and stairs.
• Cross conveyor to discharge oversize material

NUGGET TRAP

• Material moves across a nugget trap prior to entering trommel.
• In most cases 40 to 60% of gold is caught here.
• Folds down for easy cleaning.

STRUCTURES

• Utilizes Wide flange high tensile beam.
