Dear Sir,

I am doing research in fluidization area and the title of work is "Continuous Segregation of Binary Mixtures in a Gas Solid Fluidized Bed".

Actually I have to separate the solids in fast fluidized mode. So for that I need the screw feeder with neoprene impeller, which should not bypass the air from fluidization the column through the screw feeder ie there should not be

any gap between screw impeller and the horizontal cylinder.

I hope you have understood my problem, so regarding this if any manufacturer is supplying the screw feeder, I request you send the addresses.

Thanking you,
