Avimetal’s Steam Drier Module is a containerized rotary steam drying system designed for continuous drying of wet mineral concentrate, filter cake, and other moisture-bearing materials. The module integrates a screw feeder, rotary steam dryer, fabric filter, rotary valve, scrubber, fan, steam heater, and stack into one compact system. It is designed to reduce moisture content, improve material handling, support downstream smelting or refining, and provide rapid installation as part of Avimetal’s modular mineral processing plant.

Flow direction: Feed → Screw Feeder → Rotary Steam Dryer heated by Steam Heater → Rotary Valve dry product out. Off-gas from dryer → Fabric Filter → Wet Scrubber → ID Fan → Stack. The steam boiler is supplied by Avimetal's certified OEM partner with selectable fuel: natural gas, LPG, light diesel, or heavy oil. Total connected electrical load is approximately 25 kW; thermal load is approximately 325 kW delivered by boiler fuel.
