Rotary drum furnace / tilting drum furnace

Rotary drum furnaces and tilting drum furnaces require a lining with abrasion-resistant refractory material. Chemical resistance also plays a major role in the use of salt with this type of smelting furnace.

Here, very dense fireclay bricks, silimanite bricks or chemically bound bauxite bricks are used. In areas that undergo high mechanical stress on ramps and bridges, bauxite bricks with high abrasion resistance have proven themselves.
