Waelz Sustainable Products (WSP) has contracted Bruks Siwertell to supply a series of conveyors for its new zinc recycling facility.
WSP’s owners, Zinc National and Heritage Environmental Services, received permission in 2020 to go ahead with the plant’s construction in Logansport, USA.
The plant’s material handling arrangement calls for the delivery of 11 belt conveyors, a bucket elevator, and feed hoppers including all associated chute work.
Three of the belt conveyors will be installed inside lit and ventilated tube gallery structures to create a totally enclosed system.
Strategically located dust collection units have also been specified to ensure environmental protection.

The conveyor systems will handle steel mill by-product materials such as electric arc-furnace dust and pellets, carbon, and limestone, each at a typical capacity of 30 tonnes per hour.
The new facility is projected to process up to 120,000 tonnes of by-product materials annually using Waelz Kiln technology, which reclaims valuable zinc oxide from the steel dust.
Bruks Siwertell Area Sales Manager Christopher Duffy said strict environmental compliance, a proven track-record of reliable, efficient technology and the ability to deliver to a tight timeframe were critical factors in securing the order.
“Incorporating a totally enclosed system is critical because of the very dry and dusty materials,” Duffy says.
“The conveyors located inside buildings are covered and the transfer conveyors between buildings are installed in the gallery structures. This ensures environmental compliance and makes the entire material handling arrangement dust-tight to the atmosphere.”
“Zinc oxide has a number of uses from rubber and ceramics, through to lubricants and ointments. Its reclamation from industrial waste is a positive environmental step, and it is great to know that our systems are part of this sustainability move.”
