Heavy-duty drives for the Bonfiglioli feeder

Bonfiglioli Heavy-duty drives

Space-saving heavy-duty gearbox for zinc refining.

Large gearboxes are used in a wide range of application areas. The gearboxes should be as strong and robust and with the longest service life possible, however be small and variable for integration in the machine. These were exactly the criteria that were important when selecting the Transmin Low Profile Feeder (LPF) gearbox, which is used by the company Sun Metals for zinc refining. The selection for the gearbox was made quickly for the Bonfiglioli Heavy Duty HDO gearbox as it satisfied the requirements.

The LPF of the Western Australian company Transmin is a hybrid feeder, which not only combines the many advantages of belt and apron feeders but also delivers additional unique benefits the Transmin feeder has over conventional feeder technology. These include, for example, the possibility to change the conveying direction from horizontal to slanted within the same conveyor unit. The LPF is also used by the Australian company Sun Metals, in the very space-limited zinc pit. For this reason, only one compact feeder solution that fulfilled the conditions was suitable.

The lowest possible profile of the high performance feeder has, from the top surface of the belt to the bottom side of the foot plates, a vertical height of not even 1.0 m. “For these compact sizes, a compact and yet reliable gear reducer is indispensable for the LPF in order to guarantee continuous operation to our customers such as Sun Metals”, explains Tony Warren, Lead Design Engineer, Transmin.
