The cement process subjects refractory systems to continuous abrasion, alkali vapour attack, thermal shock, clinker infiltration, and reducing atmosphere exposure. Each area of the plant demands a different monolithic design based on temperature gradients, dust load, rotation speed, CO levels, and chemical volatility to ensure reliable performance and extended lining life.

This zone faces high-velocity dust laden air and alkali chloride condensation. CO levels fluctuate and temperature cycling is frequent during plant startups. The lining must resist alkali salt attack, abrasion, and thermal shock to avoid spalling and duct blockages.
