The Necessity of Reforming Rotary Drum Cooler

In the middle part of cooler, we use the palace with broken structure system, this can change the big materials into small materials. It is easy to be dried. Because there is much dust in the processing of cooling, we should use the half a palace type circular feed plate in the end of cooler, this can promise that the materials can not falling in the air so that the dust can be reduced to half, and the dust collector will have less work, so the equipment will have a long life.

The rotary drum cooler is widely used for drying the materials, the drying material is second coal consumption process and also is the important part of the cement production process, this can have the direct effect on the quality and consumption. The rotary has the advantage of simple structure, stabile operation, easy to manage, but it has the disadvantages of big heating cost, low heat efficiency, not easy to control the water, much dust and so on. So reforming the rotary drum cooler is a important task in the future. This can make the rotary more between be used in the processing of production.

The main technology of rotary drum cooler fluidized bed:

1. Equal pressure wind box, two stage combustion, separation and collection using u-shaped combustion period can not fine carbon burnout and can prolong the burnout time again.

2. E coarse pitch varying hole hood ventilation device has the good fluidization quality and combustion process, reduce the edge not uniform effect of ventilation.

3. Using large excess air coefficient, strengthening the furnace air agitation, enhanced combustion, coal in furnace burning full, uniform temperature, easy to control.

4. Adopting the reasonable structure of suspension period, low flue gas flow rate, small amount of fine ash away and heating the smoke gas high temperature can reach 1050 ℃.
