Fluidization is a versatile process with a wide range of industrial applications, particularly in industries that require efficient mixing, heat transfer, or particle size reduction. It involves suspending solid particles in a fluid (gas or liquid) to create a fluid-like state, enabling processes like drying, coating, combustion, and chemical reactions. Fluidized bed jet mills, for example, are used in industries such as chemicals, minerals, metallurgy, ceramics, and pharmaceuticals for grinding and particle size reduction. This technology is valued for its ability to produce fine, uniform particles with minimal energy consumption. Below, we explore the key industrial applications of fluidization in detail.
