CHAENG can not only supply the cooler,but also provides design,selection, installation and commissioning for the whole active lime production line
The cooler is one of the main equipment for quick lime calcining. It is widely used in building materials, chemical industry, metallurgy, etc and work as the matching facility of rotary kiln.
CHAENG can not only supply the cooler,but also provides design,selection, installation and commissioning for the whole active lime production line,this will make custom more convenient.
The main purpose of vertical cooler in lime cooling process:
It is based on the need of fast lime calcining & quick lime cooling. The vertical cooler would prevent the lime clinker from reacting when out of the kiln under the high temperature after the kiln, which can cause the crystal to get bigger, so change the activity performance. It is good for high productivity, fast delivery and storage. Through the rapid conversion of waste heat of material, high quality combustion air is obtained. it makes the cylinder with 3.5% gradient rotate in low speed. The material is feed from the top of cylinder, then it is lifted up, scattered by lifter blade.The cooling material discharge from the low end.

1. Cooler is used in lime rotary kiln, Reduced the secondary abrasion of lime clinker in the cooling process, and the lime clinker was cooled and discharged as a whole.
2. Shorten the cooling time. The cooling process needs about 40 minutes of the lime clinker. The discharge temperature < 100 ℃.
3. Increase secondary air temperature fast, and air temperature > 600 ℃.
4. The performance and physical chemical indexes of lime are effectively guaranteed. At the same time, it has the characteristics of less occupied area, optimized equipment structure and easy maintenance.
