Cooling Machine φ2.2x22 Rotary Clinker Cooler for Cement Production Line

The Cooling Machine 2.2x22 cools hot clinker and similar bulk materials by passing them through a slowly rotating cylinder against a counter-flow of cool air. The clinker tumbles down the inclined drum, and internal lifters spread it into a thin curtain that the air stream cools evenly and efficiently. Rapid, uniform cooling improves clinker grindability and cement quality, while the recovered hot air can be routed back to the kiln as secondary combustion air, saving fuel. The robust cylinder, riding rings and drive are built for continuous, high-temperature service, making this cooler a dependable part of cement and building material plants.

• Efficient Clinker Cooling: Air flowing against a thin, tumbling curtain of clinker cools the material quickly and evenly across the drum.
• Improved Clinker Quality: Rapid cooling improves clinker grindability and crystal structure, raising the quality of the finished cement.
• Heat Recovery: Hot air from the cooler can be returned to the kiln as secondary air, reducing fuel consumption and operating cost.
• Durable High-Temperature Construction: Heat-resistant shell, liners, riding rings and support rollers withstand continuous hot, abrasive duty.
• Adjustable Cooling Rate: Drum speed and air flow can be tuned to control the discharge temperature to suit downstream handling.
• Robust Reliable Drive: A sturdy drive and support system keep the drum turning reliably under a heavy, hot load.

Rotary cooling machines are used to cool cement clinker in cement plants and to cool lime, dolomite and other hot bulk materials in building material and metallurgical lines. The recovered hot air is commonly reused for combustion, improving the energy efficiency of the whole production process.

The cooler ships with the shell supported in sections and the drive, support rollers and liners crated separately. A full set of drawings and an operating manual are supplied, and each unit is inspected before dispatch. We provide a twelve-month warranty and a dependable supply of liners, rollers and drive parts to keep your cooling line reliable.
