Manipulating fluidized beds by using internals: Fluidization with baffle

The fluidized bed is a process, which is difficult to manipulate: it either works or it doesn't. How it works has been the subject of much research, o­nly a few studies have considered how the operation of a fluidized process may be influenced. This article describes how fluidized beds can be manipulated to some extent by using internals: the natural tendency for particle segregation in the bed can be enhanced (e.g. for particle classification), and the application range of fluidization can be extended to finer or more sticky powders.
