Meeting demands

Mining and quarrying equipment, amphibious and multi-terrain vehicles and water taxis all have one thing in common when it comes to power transmissions — strength, durability and the capability to handle high power and torque in demanding environments.

The world’s highest capacity mobile sizing station, in Australia, features four power transmission gear units. Manufactured by world leader in mineral sizers, MMD of Derbyshire, the station can process over 10,000 tonnes/hr of overburden — the excess material removed when extracting minerals — and can rotate through 270º.

It has a slewing discharge conveyor and an apron plate feeder, which can be raised when the unit is moving. The whole unit weighs 1,760 tonnes, and its slewing conveyor is mounted on a turntable. The unit is also mounted on tracks, which allow it to move in conjunction with the large rope shovel feeding the unit. This, in turn, discharges on to a belt conveyor system.
