| Abstract: | The process,principle and application of rotary flash dryer in zeolites production were reviewed. Compared with conventional blade dryer, rotary flash dryer features simpler operation, lower material consumption, higher yield and better product quality, with increased catalyst productivity（ 14.5 t ·d-1 to 17.5 t·d-1 ） ,decreased energy consumption （0.9 t · t-1 to 0.774 t·t-1 ） ,lower fuel gas consumption （0. 126 t ·t-1） and lower dust in emission stream（ 〈90 mg· m-3） |
