Grate Cooler

Grate Cooler

Clinker grate coolers are kiln cooling machines used to cool large quantities of hot clinker material rapidly. Clinker is spread on the grate in a certain thickness after discharging into the grate cooler from the rotary kiln. The clinker progresses through the cooler by moving along the grate and so the direction of the cooling air is at right angles to the direction of the movement of the clinker. The grate cooler functions as a cross-current heat exchanger. By this method, the clinker is cooled from 1300-1400℃ to 100℃ in just a few minutes.

• Our grate coolers allow easy customization and assembly to fit various production sizes. This speeds up the manufacturing process and simplifies maintenance and installation.
• Each grate bed can be individually adjusted, ensuring optimal clinker distribution and adaptability, a key factor in maintaining consistent cooling performance.
• Equipped with automatic flow control valves, our coolers deliver targeted air supply to specific zones, preventing air from short-circuiting and ensuring stable and efficient cooling.
• Grate plates are designed to be covered by a static layer of clinker, protecting them from extreme heat and reducing wear. This innovative approach minimizes the need for frequent replacements.
• We use special grate plates with non-contact, leak-proof seals to prevent leakage, ensuring a cleaner operation and saving on maintenance costs for hoppers and conveying systems.
• The level design of the moving grate bed and the absence of hoppers significantly reduce the cooler's height. This design choice can lead to considerable savings in construction and operational costs.
• A unique sealing structure between the grate plates allows for easy adjustments and removal, making maintenance straightforward without removing the plate's material layer.

  The sloping row is in the support roller slot, which is fixed to the bottom surface of the movable frame by bolts. When the movable frame moves, the sloping row moves along the surface of the support roller slot, thus resulting in the reciprocating motion of the movable frame.
• Shell
  The shell is made of steel, and the purpose of the refractory mineral and refractory brick covering the inner surface of shell is to prevent heat loss.
