Profile: Madden Steel Inc. designs and manufactures gold recovery & mining equipment. We also custom design gold recovery plants. Our products include gold recovery trommels, grizzly feeders, screens aggregate mining equipment, crushers, hoppers, conveyors and mixing tanks. Our gold trommels have a full power 4 point drive system and a full variable speed control. We have installed full rubber octagon screening media to help eliminate screen blockage. The screen media has 10 to 15 times the life of steel. It snaps into place in minutes, instead of long hours. Grizzly pan feeders & screen decks incorporate up to 6 drive shafts with oversized bearings & have an adjustable throw. They are reversible and have variable speed drive system to completely fine tune the feeder. They are fully lined with bolts on hardened abrasion resistant wear plates and have a water spray system that is not attached to the vibrating unit. Oscillating sluice boxes feature a true circular oscillation not just a back and forth motion. Our standard grizzly belt feeder has a 15 yard capacity with variable speed control to accommodate 50 to 400 ton per hour feed rates. The feeders also feature radio remote control grizzly dump.
