Boston Gear Series 2000 Inline Drives for Mine Belt Filter Press
A mine facility needed a reliable gearbox to replace a competitor model that failed on its
belt filter press. While mud/slurry sewage from the mine is pumped into the press, the
liquid is filtered out under pressure through fabric membranes. The remaining caked solid
material is dumped as it exits the machine. A synchronous belt drive is used to power the
continually-rotating filter membrane belts. The gearbox is positioned between the 1 HP
electric drive motor and the belted drive sprocket shaft.
Boston Gear provided a triple reduction Model 2073 inline drive with a ratio of 136:1
and a rated output torque exceeding 7,700 lb.in. to meet the challenging slow speed
application requirements. The unit features a coupling-style, NEMA C-Face motor input.
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 environment.
