KÖLLEMANN heated screw conveyors have been developed for the thermal treatment of challenging bulk and conveyed materials. They are particularly suitable for petroleum coke, dusts, pastes, slurries and similar products. Through the targeted application of thermal energy, materials can be heated, melted, dried or conditioned for subsequent process steps.
