Alkali Dust.

We, in our 7200t /day  plant, have Alkali bypass system wherein we extract about an average of about 24t of alkali powder daily.Now disposing it off is a huge problem because of the stringent pollution control over here.Can anybody have any idea how to tackle this problem?/We are collecting this dust in a truck and disposing of in some  remote area where we are getting objections from the local people over there.

Re: Alkali Dust.

Hello

Depending on the % of alkali / chlorine, it is possible to pneumatically dose this at small tonnages to the cement mill system. This can be dosing in to the cement mill bucket elevator or separator. Clyde Materials are currently doing this with a number of our customers, using our rotofeed dosing technology.

If you need any further information please do not hesitate to contact me.

Best Regards

Richard Sagar

Re: Alkali Dust.

May sound like an easy solution, but we were able to eliminate the bypass to landfilling operation by purchasing low magneisum limestone from adjacent quarries (and at a very low price). The purchased limestone was wasted by the quarries anyways.

Re: Alkali Dust.

Dear,

You can use the Alkali dust in cement mills.Keep some conveying system and add to the mills output.And if you have a number of mills you can keep one common hopper for collecting the dust and different lines for each mill.
