You may want to look into using HOLO-FLO units as an alternative for calcining gypsum. It is essentially a hollow flight design allowing the heat transfer medium to circulate around the flights and stem pipe. In your case, there is an indirect heat exchange between the product and heat transfer medium. The screws and jacketed housing are heated to the required calcining temperature. The equipment may be made from stainless steel or carbon steel material. Many gypsum manufacturers are already using hollow flight design. If you want to send your application info, I maybe able to help you with sizing estimates. Please send it to jiggger2003@yahoo.com. ■

I saw this ad in the thread at the bulk forum.

Do you have this need?

Do you have any budget or lay out of the plant on your plans.

Do you have pre project or a green field project?

I can quote to you base on your installation plant.

I need to know, feeders capacity, raw material feeder capacity, what type of process do you want, dry process or wet process.

Do you need a precalcination tower?

What type of burner do you have or are you willing to use.

I like to know material blane. Do you have raw meal mills?

Please let me know,

I appreciate your cooperation,

Thanks in advance and best regards,
