Boston Gear Series 2000 Inline Drives for Mine Sedimentation Tanks
A mine operator in the Western US needed replacement gearboxes for its sedimentation
tank drives. The circular tanks have a rake or scraper arrangement at the bottom to
remove sludge, and a skimmer at the top to remove the scum. The scrapers and
skimmers rotate continuously at very slow speeds.
Positioned above the center of the tank, the speed reducers are mounted between the
electric drive motor and the vertical scraper/skimmer driveshaft that extends to the bottom
of the tank.
To meet the challenging slow speed application requirements, Boston Gear supplied a
triple reduction Model 2073 with a ratio of 136:1 and a rated output torque exceeding
7,700 lb.in. The unit features a coupling-style, NEMA C-Face motor input. The energy
efficient units replaced worn worm gear reducers.
Low maintenance Series 2000 models feature automatic magnetic entrapment of wear
debris and synthetic lubrication for extended gear life. Premium acrylic paint emulsion
pigmented with alloy 316 stainless steel flake provides high corrosion & abrasion
resistance for long term durability in this tough mine environment.
