We produce Waelz oxide in our rotary kiln plant.
The zinc-containing input materials are enriched in our rotary kiln using the so-called Waelz process to form Waelz oxide with a zinc content of at least 56 %. For this purpose, the input materials are introduced into the 40 m long rotary kiln together with other additives and handled at approx. 1,200°C.
