The feed pipe lining is exposed to substantial abrasive actions associated with a large amount of undersized materials and thermal loads. High-aluminous and andalusite-based materials with silicone-carbide (SIC) admixtures, concretes based on high-aluminous fire-clay grog or bauxite are suitable for the lining of these assemblies. Heat insulation is made of calcium silicate slabs; however, considering installation complexity for this unit, is it highly recommended to use lightweight concretes applied by smearing technique. Use of lightweight concrete substantially reduces the time of installation and enhances the overall lining resistance.
