Grate Cooler

Process Description

Grate cooler machine of CHAENG, adopts the new efficient grid plate structure which with very few leakage occurring, less abrasion and longer service life.

The grate cooler is the main equipment in calcining system of the cement plant. Its main function is to cool and transport the cement clinker. It also provides hot air for rotary kiln and decomposing furnace, and it is the main equipment for heat recovery in calcining system.

Grate cooler of CHAENG is new energy-saving clinker cooling equipment, which adopts international advanced flow-control technology, makes continuous optimization and development relying on advanced thermal technology. Its output can be improved by 20% compared with traditional grate cooler. Heat consumption can be saved more than 10%.

1. Intelligent control of cooling air volume, energy saving

The optimized grate bed is separated for providing air, and the air volume of each cooling area is controlled accurately to achieve efficient cooling and high heat recovery. The energy saving effect is remarkable.

2. Good wear resistance and easy maintenance

Unique external supporting roller and guide device. The grate bed is support by a separate carrying support roller, which has high surface hardness and good wear resistance. It can effectively prevent the grate bed from sinking, and make the maintenance very convenient.

3. Convenient installation without leakage

4. Long working time

It is made, with a special machining process, by the material of alloy casting steel, which has character of high strength, high temperature resistance and anti-oxidant wear. Thus the machine has high airflow penetration and long service life.
