Vibrating fluidised bed dryers

Vίbratίng fluidίsed bed dryers (free-running oscillation or reso-nance systems)
are used for bulk materials with a wide range of grain sizes.
Their partίocular advantages are:

• The vibration enables optimum drying of products with fluctuating grain sizes even at low gas velocity
• The vibration prevents the formation of bubbles ίn fine-grained products thus ensuring enhanced energy efficiency
• When drying products with a wide range of grain sizes. The vibration prevents segregation of the material by loosening up coal’s grains
• The dryer can be emptied with ease as the particles are transported through the dryer by means of vibration. Changeover from one product to another ίs therefore quick and easy
•  Adjusting the vibration influences the product residence time and has a particularly beneficial effect on quality
