Apr 01 2014With these dryers moisture is on the surface of the solid Non-adiabatic dryers involve situations where a dryer does not use heated air or other gases to provide the energy required for the drying process Dryer classification can also be based on the mechanisms of heat transfer as follows: • Direct (convection) • Indirect or contact

Methods of Thermal Drying

Jul 22 2020Primary sludge is anaerobically digested first and then blended with thickened waste activated sludge The sludge mixture is then dewatered in centrifuges to about 26% solids and fed into four drying trains each comprising a rotary drum dryer Each dryer is sized to evaporate water from dewatered sludge at a rate of 8500 kg/h (18 700 lb/ hr)

Belt drum and fluid bed dryers

The dewatered sludge is granulated in a mixer tailored to the application It is then dried in the triple-pass drum (three concentric cylinders revolving around a joint axis) in a convective drying process to 10% residual moisture The sludge is conveyed pneumatically by the stream of hot gases ensuring an evenly dried pasteurized product
