Transmin approached A-Ward™ to design and manufacture four custom container unloaders that would enable a nickel mining customer to safely unload steel balls into their ball mills. A ball mill is a type of grinder that is used to grind and downsize mined materials such as copper, gold, iron ore and nickel. These container unloaders were required to receive full 20ft containers via large forklifts and tilt containers to 20 degrees so that the 40mm and 70mm steel balls could be unloaded into concrete storage hoppers. Transmin challenged A-Ward to supply a solution that would eliminate all operator safety risks and integrate seamlessly with their ball mills.


A-Ward™ supplied four slightly customised Flat Deck container unloaders. A-Ward’s standard container unloaders tilt to a maximum angle of 70 degrees, however, to fulfil Transmin scope requirements, this product was designed to be limited to a 20-degree tilt, due to the low angle requirement to shift steel balls. The tilt angle can also be locked at any stage for guaranteed stability. Other upgrades added for this project included a high-specification pebble grey paint finish, a WEG electric motor, with IP66 electrical rating, and a safety sensor package to integrate with the end user’s PLC system.


  • Eliminated safety risk (ball unloading and milling totally enclosed and hands free).
  • Reduction in labour (one operator)
  • Increases in productivity and profit.
