The waste heat of 200 ° C or more generated chemical processes is utilized for the drying process, so that the energy consumed in drying can be used at no additional cost

• Byproduct smelting sludge/slurry using waste heat of smelting process

• The existing discarded waste heat can be recycled, minimizing the energy required for drying.
• Minimizing equipment costs because the post-treatment equipments for exhaust gas treatment after drying can share existing waste heat treatment plants.
