Bonfiglioli HDO 170: The answer to a tight problem

A compact but powerful Bonfiglioli HDO 170 drive selected for its durability and reliability under all conditions is helping power a Transmin low profile feeder (LPF) for a Sun Metals zinc refining operation.

Bonfiglioli’s HDO 170 drive – which has been operating efficiently and productively since commissioning – was engineered and assembled in Australia to provide a space-saving solution for Sun Metals, who needed to fit the LPF with attached drive into a tight space in their existing pit. It features a 75 kW motor that produces 127,700 Nm of torque.

“The compact design was one of the major benefits of using a Bonfiglioli drive for Sun Metals’ LPF. Additionally, the service and support from the Bonfiglioli team is always prompt and professional,” says Tony Warren, lead design engineer, Transmin.

Transmin is a world-class provider of innovative engineered equipment, supplies and services to the manufacturing, mining, resources and bulk materials handling industries, with engineered equipment currently deployed in over 60 countries.

The Transmin LPF handles zinc concentrate at 400tph and is positioned beneath a large hopper, which is filled by side tipping trucks. The zinc concentrate is then fed into the process plant for refining into zinc metal.

“The reliability of Bonfiglioli’s drives is first-class. We’ve used their drives in numerous projects across Australia, including some in harsh conditions, and their durability and reliability have always been outstanding,” says Mr Warren.

“Transmin’s LPF is essentially a hybrid feeder delivering the advantages of both belt and apron feeders, plus additional unique benefits over conventional feeder technology, including the ability to change direction using a bend transition. A reliable drive is essential to power the LPF and provide consistent performance for our customers like Sun Metals,” he says.

Mr Warren adds that apart from the quality that is engineered into the heavy-duty drive, it’s the service from Bonfiglioli that sets it apart. “Their team worked with us from day one to provide a custom-tailored solution for Sun Metals, and they were there throughout the entire process. They have also been helpful and available for any after-sales service we have needed.”

HDO drives

Bonfiglioli’s HDO bevel helical gear reducer series optimises performance with compact dimensions and flexibility. The gear case is made from nodular cast iron to guarantee rigidity in all circumstances while the gears are integrally ground finished on their profile to ensure quiet and vibration-free operation even in the harshest conditions.

“The HDO series is ideally suited to Australian industry, because it is optimised for reliable performance in the harshest conditions and can be easily customised to suit individual applications,” says Fred Whalley, WA sales manager, Bonfiglioli.,
