60% Al2O3 Pallet Side Retainer Brick is essential refractory material in the annular cooler trolley, installed on the inner and outer sidewalls of the trolley.The annular cooler (ring cooler) is a critical piece of equipment in the sintering process used to cool high-temperature sintered ore. The grate plate bricks of the trolley are key components of the trolley structure, forming the sidewalls of the trolley container. These bricks withstand the thermal load and mechanical stress of high-temperature sintered ore while ensuring the sealing and cooling efficiency of the trolley.

As a cooling device for pellets, the annular cooler subjects its sidewall bricks to cyclic thermal shocks as they travel with the pallets from high-temperature zones to low-temperature zones repeatedly. Additionally, these bricks endure constant scouring from materials falling from the kiln discharge. Therefore, pallet sidewall bricks must exhibit exceptional thermal shock resistance and high mechanical strength.

Through years of research and practical experience, our company:Shandong Luming New materials Technology Co.,Ltd has developed high-strength sidewall bricks with outstanding thermal shock stability. These bricks deliver a service life exceeding two years, earning widespread acclaim from our customers.

Key Features:

Superior thermal shock resistance – Withstands repeated temperature fluctuations.

High mechanical strength – Resists impact and abrasion from falling materials.

Long service life – Over 24 months in demanding conditions.

Proven performance – Trusted by pellet plant operators worldwide.

Our high-performance sidewall bricks ensure reliable operation, reduced downtime, and lower maintenance costs for your pellet cooling system.

Function of Grate Plate Bricks

Grate plate bricks are essential refractory materials in the annular cooler trolley, installed on the inner and outer sidewalls of the trolley. Their main functions include:

Seal: Prevent hot air and fine materials from escaping from the sides of the trolley, ensuring cooling efficiency.

Bear Load: Support the weight of the material and absorb impacts during operation.

Insulate Heat: Block heat dissipation to the outside, protecting the trolley's steel structure and extending its service life.

Resist Abrasion: Withstand the abrasive forces of material and airflow.

Characteristics of Annular Cooler Trolley Side Plate Bricks

Due to their specific working environment, annular cooler trolley side plate bricks typically possess the following characteristics

High-Temperature Resistance: Refractoriness typically needs to exceed 1500°C to handle the high temperatures of sintered ore.

Abrasion Resistance: Material sliding, tumbling, and cool air blowing on the trolley can cause wear, so excellent abrasion resistance is required.

Thermal Shock Resistance: Material temperatures fluctuate drastically during annular cooler operation, so the side plate bricks must be able to withstand these temperature variations without cracking.

Corrosion Resistance: Sintered or pelletized materials may contain corrosive substances like sulfides and alkali metals, which can chemically corrode the refractory bricks.

Good Structural Stability: Must maintain structural integrity under high loads, high temperatures, and vibrations, resisting deformation or collapse.

Precise Dimensions and Shapes: To ensure proper sealing and overall integrity between trolleys, side plate bricks are often custom-made into specific shapes, such as L-shaped or curved bricks.
