Kiln dust emission by preheater

we are interested to receive a solution for granulating the clinker dust to solve the enviroment problems . noting that the dust particle size is a round 0.1mm with temp.250C.

I presume that the clinker needs to be granulated in the kiln? If the clinker is dusty in the kiln then it is likely to be related to a sulphur cycle in the kiln. So the solution to the dusty clinker would be to solve the sulphur cycling problem.

Dear jalalco can you send me more kiln operation and other technological data for answering your question. I want to know:

1) What kind of raw materials you are using?

2) What are your raw mix & clinker modules (LSF, SF, AR)?

3) What kind of fuel are you using ?

4) Kiln dimensions and kiln system type.

5)Temperature of gases in the two ends of the kiln, before cyclones and after  preheater tower.

6) Rotation speed of the kiln, etc.

Thank you for the reply,,

mostly clinker dust hapen in north africa area ,  due to raw material contents. no problem in the design.

we are in the installation stage , and intend to install the granulator so we make the clinker dust into grains with more than 2mm size. The produces grains will be throughn away , and will not used . We need this to protect the environment.

Can any suggest manufacturers for such granulators ,

Thanks for the cooperation.
