Germany: Aumund and Holcim have demonstrated an electric linear calcination conveyor (eLCC) at Aumund’s headquarters in Rheinberg, Germany. Initial tests of the eLCC have reportedly demonstrated efficient thermal activation of clay through a combination of radiant heat and material circulation. In 2020, Aumund Fördertechnik teamed up with Holcim for a project focused on the electrical calcination of clay using an Aumund pan conveyor.
The company stated that the eLCC system is fully enclosed and insulated, minimising energy requirements and heat loss, with its compact design allowing for expansion of production capacities. It can operate with electrical heating elements powered by 100% renewable energy sources like wind or solar. The first industrial plant utilising this technology will be constructed in 2025.
