A Fluidized Bed Classifier is an essential equipment used in the processing of minerals, coal, and other materials.
In a Fluidized Bed Classifier, a mixture of solid particles is introduced into a vertical column, where a liquid (usually water) is introduced upwards through the material bed. The particles are subjected to both gravitational forces and the upward force of the water stream. The bed is "fluidized," meaning that the solid particles are suspended within the water stream.
