Smelter drag conveyor modernization

The design of a drag conveyor has a major impact on the service life of both the conveyor and its chain.

In 2023, we modernized an existing conveying system for a European copper smelter by redesigning and supplying a new drag chain conveyor for boiler dust handling. The conveyor transports 30 t/h of metallurgical dust to the second level of the smelter at an inclination of 35°. The total conveyor length is almost 60 metres.

The conveyor is equipped with Kopar’s own boron steel conveyor chain. During an equipment inspection carried out in autumn 2026, the chain was found to be still like new after 3.5 years of continuous operation. Kopar’s boron steel conveyor chain has proven its performance in demanding smelter applications.

When operating conditions are taken into account in the design and every component is selected specifically for those conditions, the result is a durable, reliable system with a long service life.

Forged conveyor chains

In the conveyors of the heat recovery boilers of the smelters, the chain operates under constant tensile load, high temperature and often under an impact load of material. Under such conditions, design, material selection and sizing are of crucial importance.

We supplied two chain conveyors for the collection and transportation of metallurgical converter dust at a copper smelter in Chile in 2026. Demanding conditions and strict quality regulations led Codelco El Teniente to once again choose Kopar's robust chain conveyors, which are designed taking into account the special needs of smelters.
