Suspension block lining of the grate cooler vault in rotary kilns

The article describes a project involving block lining for the vault of a rotary kiln grate cooler. A special feature of the vault design is the use of blocks made from medium-cement mullite- siliceous concrete containing andalusite and silicon carbide. The heat-insulation layer was executed from selfswelling cellular concrete. The economic effect of the new lining is based on reducing the labour input, and the duration and periodicity of current repairs. The lining materials were made by OOO Metpromsnab.
