Comessa - Static Fluidized Bed - Brochure

The fluidization is a state of dynamic balance of a divided solid in an ascending moving gas. It confers hydraulic properties to solids (angle of repose equal to zero, easy spreading, total filling of a receiver in which the product is fluidized). Such method of bringing in contact a solid with a gas, allows high mass and heat transfers. Mechanical energy transferred by gas to the particles is low enough to prevent attrition. Crystals for instance will remain bright and will keep sharp edges.
