Rotary cooler
The cooler is one of the main equipment in the rotary kiln production system.
Its role is to cool the 1000~1300°C clinker from rotary kiln to 200°C and below by heating exchange of moving materials and airflow inside the rotating barrel.
The quality and grindability after cooling down is improved. The air from the cooling clinker is injected into the kiln as secondary circulating air, raising the thermal efficiency of the kiln.
Rotary cooler working principle
In the natural situation, the slope of the Cooler cylinder is 3.5% to 5%, keeping low-speed rotation. The material is fed from the end of the Cylinder (high side), and a circular lifting plate keeps the materials scattered, lifting and moving down. Cooling material is discharged from the low end, and preheated air is sent into the rotary kiln for calcinations.
