Rotary dryers are ideally suited for large capacity applications where the feed has uneven particles size distribution. These dryers are vary robust and have low maintenance cost. The Rotary Dryer is essentially an inclined shell which is rotating . The feed is showed thoughout the shell by spirally mounted lifters into a stream of hot air

in a fluidized bed dryer. Here the wet sand particles are fed to the dryer through a conveyor. The hot air from the bottom of the dryer passes through the nozzles embedded in the dryer bed and rises up. This upwind do not allow the wet sand particles to settle down. Instead, the sand particles are in a fluidized state inside the dryer

The rotary drum dryer is the most common type of dryer used for this task [1, 2]. Depending on the moisture content of the biomass, the operating temperature for such dryers is around 300-600 C [3]. Such a high temperature maximizes the moisture evaporation rate and shortens the residence time of biomass in the drum

The methods used to measure the sizes of dried particles include sieving, microscopy, sedimentation and laser techniques. Pressure spray nozzles can produce particles ranging in size from 20 to 600 microns, depending on the nozzle type, feedstock properties and operating conditions

Oct 02, 2016 Three different sizes of particles are considered as diameter of 20 mm, half size 10 mm and fifth size 4 mm; so that the particle properties are shown in Table 3. In order to evaluate the effects of particle size distribution, three main cases (Case 1–3 in Table 4 ) are defined so that the mass of the bed remains constant at 156.6 g
