Is fluidized bed granulation widely used in the fertilizer and industrial salt industries?
Thread Content
What are the main methods currently used for granulating fertilizers and industrial salts? Squeeze? Tall tower? Crystallization? Will the fluidized bed process have a market in this field? If you know any, please share
Since the introduction and promotion of urea, there has been no fluidized bed process or high-tower granulation; as for other salts, it is not clear
Fluidized beds can produce particles that are uniform and free of dust, with a dense surface structure; they have reduced hygroscopicity and are easy to store. They have many applications in the field of industrial salts, but they have not yet been widely adopted in China, where extrusion granulation seems to be more common. It can be granulated from a solution or from a powder.
Currently, drying is the main method, with granulation also being widely used. There is a lot of drying done, whether it’s organic or inorganic. Only a 18-meter version has been designed for granulation.
