S7 or S8 Gold Trommel

Our 300 tons per hour rated S8 gold trommel and 200 tons per hour rated S7 gold trommel have a full power four point drive system, which eliminates the chain drive, and has a full variable speed control. It has an extra heavy shell and is completely lined with abrasion resistant plate in all wear areas. It also features additional reinforcement in drive locations, incorporates oversized shafts, and incorporates oversized bearings.

Testing showed that some of the biggest complaints with trommels is screen blockage, so we have taken and installed full urethane tapered relief octagon screening media to help eliminate this issue, an expensive but needed adaptation. Another advantage with this screen media is it has 10 to 15 times the life of steel. Additionally, the screen media snaps into place, which takes only minutes instead of days, or even weeks, as with other systems.
