Pressure nozzle spray dryer, high slurry solids content after pressure atomization granulation, dry spherical granular, dry, finished, free mobility, it can even quickly fill pressuremembrane. Residual water content and bulk specific gravity constant need isostatic molding products suitable for dry, comparable to the original mechanical granulation suppression of the molds used to improve the service life 4-8 times, and the pressing of the product, consistency, finish, can be used in the tiles, tableware, ceramic substrates, ceramic materials, ferrite magnetic materials and other industries.
