For mining and smelting plants we mainly deliver transport screw conveyors, dosing screws, rotary valves, silo- feeders and dischargers.
The machines are produced in different steel qualities, depending on customers preferences and corrosion and wear characteristics of steels in different environments.
Hardox is widely used in this industry, but also common stainless steels such as AISI 304 and AISI 316. From time to time there are requirements beyond this in which we typically deliver machines in Duplex qualities of e.g. AISI 310 which is well suited for operations in high temperatures.
