Phospho Gypsum Granulation

What are you doing with the gypsum now?

A simple drum dryer is an obvious choice. With rubber inserts or chains to prevent agglomeration on the internal walls. It should act as a granulator as well.

I have in my mind's eye a super phosphate dryer/granulator.

Dear Sir,

Currently we are sun drying to about 10 to 15% moisture content and bagging to sell for cement industry.

On trial we have taken in dryer of capacity 7.5tph at 15 to 20% moisture content at inlet (mixing with dolomite) and drying air flow rate of about 10000 m3/hr at 300 deg C with dryer outlet 65 deg C, but found heavy build-up dryer and material becomes powdery too.

regards,

SNA

Please advice me of the vendor for bagging machine you are use it, or you made it manually?
