VIBRATING FLUIDIZED BED

VIBRATING FLUIDIZED BED PRINCIPLE Fluidization confers to a divided solid the properties of a fluid. Products with a wide particle size distribution or including large particles, cannot be processed in a static fluidization equipment. It is the same for products discharged from centrifuges which are sticky or include lumps and which will not permit treatment by direct fluidization. Comessa developed the vibrating fluidized bed to solve most of these delicate drying problems. In such case, vibration insures a better fluidization and allows transport of largest particles or lumps. ADVANTAGES OF THIS TECHNOLOGY H andling of sticky products (from centrifuges or filters) B reaking soft lumps eventually formed during process A dapted to a wide particle size distribution U niform product temperature, moisture and treatment Low attrition of particles High evaporation rate R educed footprint and simplified layout Easy adjustment (residence time, temperature, airflows) Multiple processing in one single equipment Adjustable fines removal ratio MAIN APPLICATIONS MAIN PROCESSES PILOT TEST LABORATORY All kind of powders, crystals, beads, granules for all industries (chemical, food, mineral, etc .) Drying, cooling, calcining, reaction, roasting, dehydration, solvant removal, etc. For determination of vibrating fluid bed parameters and possibility to perform semi industrial tests or rental of a complete pilot unit. 101, rue du Rhin-Napoléon 67100 STRASBOURG FRANCE
