Rotary Cement Kiln Refractories

High-quality magnesia bricks and refractory solutions for all cement kiln zones

Reliable Refractories for Cement Kilns

The refractory lining is a critical component in rotary cement kiln operation. It protects the steel kiln shell from temperatures exceeding 1,450°C in the burning zone and withstands chemical attack from raw materials and fuel.

Alzar FZE represents MGC for supplying high-quality magnesia bricks for cement kilns in the UAE and GCC countries. We offer a complete range of refractory products for all kiln zones, with technical support for material selection and lining design.

Our Refractory Products

Magnesia-Spinel Bricks

Designed for the burning zone of rotary cement kilns where temperatures exceed 1,450°C. They provide excellent resistance to chemical and thermal corrosion. Supplied by MGC.

Magnesia-Chrome Bricks

Used in transition zones of cement kilns where high resistance to mechanical and chemical wear is required. Suitable for areas with significant thermal fluctuations.

Dolomite Bricks

Used in specialized kiln sections where high alkali resistance is required. They provide reliable performance in environments with high alkali and sulfate content.

Castable Refractories

Monolithic refractories for preheater cyclones, calciner, cooler, and auxiliary equipment. Includes insulating materials and anchoring systems.
